The recommended PCB land pattern for the 4922R-31L can be found in the API Delevan application note AN-013, which provides a detailed layout and footprint recommendation for optimal performance and reliability.
While the datasheet specifies an operating temperature range of -40°C to +125°C, the 4922R-31L is designed to maintain its inductance and Q factor within a reasonable tolerance up to 150°C. However, it's essential to derate the component according to the specific application and environmental conditions.
The SRF of the 4922R-31L is not explicitly stated in the datasheet, but it can be estimated using the inductance and capacitance values. Typically, the SRF of this inductor is around 500-600 MHz, but this may vary depending on the specific application and PCB layout.
Yes, the 4922R-31L is compatible with lead-free soldering processes, including RoHS and WEEE compliance. The component's termination is made of a lead-free, tin-silver-copper alloy that meets the requirements of these regulations.
To prevent damage and ensure reliability, it's essential to store the 4922R-31L in a dry, cool place, away from direct sunlight and moisture. Handling should be done with anti-static precautions, such as using an ESD wrist strap or mat, to prevent electrostatic discharge damage.
