0.5mm - Depth
In electronic components, "Depth" typically refers to the measurement of the distance from the front to the back of the component. It is an important parameter to consider when designing or selecting components for a project, as it determines how much space the component will occupy within a circuit or device. The depth of a component can impact the overall size and layout of the circuit board or enclosure in which it will be installed. It is usually specified in millimeters or inches and is crucial for ensuring proper fit and functionality within the intended application.
4mm - Frequency
In electronic components, the parameter "Frequency" refers to the rate at which a signal oscillates or cycles within a given period of time. It is typically measured in Hertz (Hz) and represents how many times a signal completes a full cycle in one second. Frequency is a crucial aspect in electronic components as it determines the behavior and performance of various devices such as oscillators, filters, and communication systems. Understanding the frequency characteristics of components is essential for designing and analyzing electronic circuits to ensure proper functionality and compatibility with other components in a system.
2.4GHz - Power Supplies
an electronic circuit that converts the voltage of an alternating current (AC) into a direct current (DC) voltage.?
3V - Power - Output
Power Output in electronic components refers to the amount of electrical power that a device can deliver to a load. It is typically measured in watts and indicates the effectiveness of the component in converting electrical energy into usable work or signal. Power Output can vary based on the component's design, operating conditions, and intended application, making it a critical factor in the performance of amplifiers, power supplies, and other electronic devices. Understanding the Power Output helps in selecting appropriate components for specific applications to ensure efficiency and reliability.
0dBm - RF Family/Standard
The parameter "RF Family/Standard" in electronic components refers to the specific radio frequency (RF) technology or standard that the component complies with or is designed for. RF technology encompasses a wide range of frequencies used for wireless communication, such as Wi-Fi, Bluetooth, cellular networks, and more. Different RF standards dictate the frequency bands, modulation techniques, data rates, and other specifications for communication systems. Understanding the RF family/standard of a component is crucial for ensuring compatibility and optimal performance in RF applications.
General ISM > 1GHZ - Data Rate (Max)
Data Rate (Max) refers to the maximum rate at which data can be transferred or processed within an electronic component or device. It is typically measured in bits per second (bps) or megabits per second (Mbps). This parameter is important for determining the speed and efficiency of data transmission or processing in various electronic applications such as computer systems, networking devices, and memory modules. A higher data rate indicates that the component is capable of handling larger volumes of data at a faster pace, leading to improved performance and responsiveness in electronic systems. It is crucial to consider the Data Rate (Max) specification when selecting electronic components to ensure compatibility and optimal functionality for specific applications.
2Mbps - Serial Interfaces
A serial interface is a communication interface between two digital systems that transmits data as a series of voltage pulses down a wire. Essentially, the serial interface encodes the bits of a binary number by their "temporal" location on a wire rather than their "spatial" location within a set of wires.
SPI - Current - Receiving
Current - Receiving refers to the amount of electrical current that an electronic component or device is capable of accepting from a power source or another component in a circuit. It indicates the maximum current that can be safely received without causing damage or malfunction. This parameter is crucial for ensuring compatibility and reliability in electronic designs, as exceeding the rated receiving current can lead to overheating or failure of the component.
11.1mA~12.3mA - Current - Transmitting
Current - Transmitting is a parameter used to describe the maximum amount of electrical current that an electronic component can handle while in the transmitting mode. This parameter is crucial for components such as transistors, diodes, and integrated circuits that are involved in transmitting signals or power within a circuit. Exceeding the specified current transmitting rating can lead to overheating, component failure, or even damage to the entire circuit. Designers and engineers must carefully consider this parameter when selecting components to ensure the reliability and performance of the electronic system.
7mA~11.3mA - Modulation
In electronic components, modulation refers to the process of varying one or more properties of a periodic waveform, known as the carrier signal, in order to encode information. This modulation technique is commonly used in communication systems to transmit data efficiently over long distances. By modulating the carrier signal, information such as audio, video, or data can be embedded onto the signal for transmission and then demodulated at the receiving end to retrieve the original information. There are various types of modulation techniques, including amplitude modulation (AM), frequency modulation (FM), and phase modulation (PM), each with its own advantages and applications in different communication systems.
GFSK - Sensitivity (dBm)
Sensitivity (dBm) is a parameter used to measure the minimum input power level required for an electronic component or device to operate effectively. It is typically expressed in decibels relative to one milliwatt (dBm), which is a common unit of power measurement in the field of electronics. A higher sensitivity value indicates that the component can detect weaker input signals, making it more responsive and capable of functioning in low-power conditions. Sensitivity is an important specification for devices like receivers, sensors, and transducers, as it directly impacts their ability to detect and process signals accurately. Manufacturers often provide sensitivity ratings to help users understand the performance capabilities of the component in different operating conditions.
-85 dBm - Length4mm
- Height Seated (Max)
Height Seated (Max) is a parameter in electronic components that refers to the maximum allowable height of the component when it is properly seated or installed on a circuit board or within an enclosure. This specification is crucial for ensuring proper fit and alignment within the overall system design. Exceeding the maximum seated height can lead to mechanical interference, electrical shorts, or other issues that may impact the performance and reliability of the electronic device. Manufacturers provide this information to help designers and engineers select components that will fit within the designated space and function correctly in the intended application.
0.95mm - Radiation Hardening
Radiation hardening is the process of making electronic components and circuits resistant to damage or malfunction caused by high levels of ionizing radiation, especially for environments in outer space (especially beyond the low Earth orbit), around nuclear reactors and particle accelerators, or during nuclear accidents or nuclear warfare.
No - RoHS Status
RoHS means “Restriction of Certain Hazardous Substances” in the “Hazardous Substances Directive” in electrical and electronic equipment.
ROHS3 Compliant
