Specifications
- TypeParameter
- Factory Lead Time4 Weeks
- Mounting Type
The "Mounting Type" in electronic components refers to the method used to attach or connect a component to a circuit board or other substrate, such as through-hole, surface-mount, or panel mount.
Surface Mount - Package / Case
refers to the protective housing that encases an electronic component, providing mechanical support, electrical connections, and thermal management.
Module - Operating Temperature
The operating temperature is the range of ambient temperature within which a power supply, or any other electrical equipment, operate in. This ranges from a minimum operating temperature, to a peak or maximum operating temperature, outside which, the power supply may fail.
-20°C~85°C - Part Status
Parts can have many statuses as they progress through the configuration, analysis, review, and approval stages.
Active - Moisture Sensitivity Level (MSL)
Moisture Sensitivity Level (MSL) is a standardized rating that indicates the susceptibility of electronic components, particularly semiconductors, to moisture-induced damage during storage and the soldering process, defining the allowable exposure time to ambient conditions before they require special handling or baking to prevent failures
Not Applicable - Voltage - Supply
Voltage - Supply refers to the range of voltage levels that an electronic component or circuit is designed to operate with. It indicates the minimum and maximum supply voltage that can be applied for the device to function properly. Providing supply voltages outside this range can lead to malfunction, damage, or reduced performance. This parameter is critical for ensuring compatibility between different components in a circuit.
3V~3.6V - 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.
2.412GHz~2.484GHz - Data Rate
Data Rate is defined as the amount of data transmitted during a specified time period over a network. It is the speed at which data is transferred from one device to another or between a peripheral device and the computer. It is generally measured in Mega bits per second(Mbps) or Mega bytes per second(MBps).
54Mbps - Protocol
In electronic components, the parameter "Protocol" refers to a set of rules and standards that govern the communication between devices. It defines the format, timing, sequencing, and error checking methods for data exchange between different components or systems. Protocols ensure that devices can understand and interpret data correctly, enabling them to communicate effectively with each other. Common examples of protocols in electronics include USB, Ethernet, SPI, I2C, and Bluetooth, each with its own specifications for data transmission. Understanding and adhering to protocols is essential for ensuring compatibility and reliable communication between electronic devices.
802.11b/g/n - 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.
16dBm - 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.
WiFi - Antenna Type
There are several different types of antennas in three broad categories: omni-directional, directional, and semi-directional.
PCB Trace - Sensitivity
Sensitivity in electronic components refers to the degree to which the output of a device responds to changes in input. It indicates how effectively a component translates a specific input signal into an observable output. High sensitivity means that even small variations in input can produce significant changes in output, making the device more responsive to signals. Sensitivity is crucial in applications where precise measurements or signal detection are required.
-90dBm - 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.
ADC, I2C, PWM, SPI, UART - 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.
11.1mA - 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.
64-QAM, BPSK, CCK - RoHS Status
RoHS means “Restriction of Certain Hazardous Substances” in the “Hazardous Substances Directive” in electrical and electronic equipment.
RoHS Compliant
