- 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.
-55°C ~ 155°C - Series
In electronic components, the "Series" refers to a group of products that share similar characteristics, designs, or functionalities, often produced by the same manufacturer. These components within a series typically have common specifications but may vary in terms of voltage, power, or packaging to meet different application needs. The series name helps identify and differentiate between various product lines within a manufacturer's catalog.
RN73R - Size / Dimension
In electronic components, the parameter "Size / Dimension" refers to the physical dimensions of the component, such as its length, width, and height. These dimensions are crucial for determining how the component will fit into a circuit or system, as well as for ensuring compatibility with other components and the overall design requirements. The size of a component can also impact its performance characteristics, thermal properties, and overall functionality within a given application. Engineers and designers must carefully consider the size and dimensions of electronic components to ensure proper integration and functionality within their designs.
0.126 L x 0.063 W (3.20mm x 1.60mm) - Tolerance
In electronic components, "tolerance" refers to the acceptable deviation or variation from the specified or ideal value of a particular parameter, such as resistance, capacitance, or voltage. It indicates the range within which the actual value of the component can fluctuate while still being considered acceptable for use in a circuit. Tolerance is typically expressed as a percentage or a specific value and is important for ensuring the accuracy and reliability of electronic devices. Components with tighter tolerances are more precise but may also be more expensive. It is crucial to consider tolerance when selecting components to ensure proper functionality and performance of the circuit.
±0.25% - Number of Terminations2
- Temperature Coefficient
The resistance-change factor per degree Celsius of temperature change is called the temperature coefficient of resistance. This factor is represented by the Greek lower-case letter “alpha” (α). A positive coefficient for a material means that its resistance increases with an increase in temperature.
±50ppm/°C - Resistance
Resistance is a fundamental property of electronic components that measures their opposition to the flow of electric current. It is denoted by the symbol "R" and is measured in ohms (Ω). Resistance is caused by the collisions of electrons with atoms in a material, which generates heat and reduces the flow of current. Components with higher resistance will impede the flow of current more than those with lower resistance. Resistance plays a crucial role in determining the behavior and functionality of electronic circuits, such as limiting current flow, voltage division, and controlling power dissipation.
2.49 kOhms - Composition
Parameter "Composition" in electronic components refers to the specific materials and substances used in the construction of the component. It encompasses the chemical and physical elements that make up the component, influencing its electrical, thermal, and mechanical properties. The composition can affect the performance, reliability, and durability of the component in various applications. Understanding the composition is essential for optimizing the design and functionality of electronic devices.
Thin Film - Power (Watts)
The parameter "Power (Watts)" in electronic components refers to the amount of electrical energy consumed or dissipated by the component. It is a measure of how much energy the component can handle or generate. Power is typically measured in watts, which is a unit of power that indicates the rate at which energy is transferred. Understanding the power rating of electronic components is crucial for ensuring they operate within their specified limits to prevent overheating and potential damage. It is important to consider power requirements when designing circuits or selecting components to ensure proper functionality and reliability.
0.25W, 1/4W - Failure Rate
the frequency with which an engineered system or component fails, expressed in failures per unit of time. It is usually denoted by the Greek letter λ (lambda) and is often used in reliability engineering.
- - Features
In the context of electronic components, the term "Features" typically refers to the specific characteristics or functionalities that a particular component offers. These features can vary depending on the type of component and its intended use. For example, a microcontroller may have features such as built-in memory, analog-to-digital converters, and communication interfaces like UART or SPI.When evaluating electronic components, understanding their features is crucial in determining whether they meet the requirements of a particular project or application. Engineers and designers often look at features such as operating voltage, speed, power consumption, and communication protocols to ensure compatibility and optimal performance.In summary, the "Features" parameter in electronic components describes the unique attributes and capabilities that differentiate one component from another, helping users make informed decisions when selecting components for their electronic designs.
Automotive AEC-Q200, Moisture Resistant - 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.
0.028 (0.70mm) - Ratings
The parameter "Ratings" in electronic components refers to the specified limits that define the maximum operational capabilities of a component. These ratings include voltage, current, power, temperature, and frequency, determining the conditions under which the component can function safely and effectively. Exceeding these ratings can lead to failure, damage, or unsafe operation, making it crucial for designers to adhere to them during component selection and usage.
