PM1812-221J-RC Details

The recommended land pattern for the PM1812-221J-RC can be found in the Bourns Application Note S-8151, which provides a detailed guide for PCB layout and land pattern design.
The PM1812-221J-RC has a maximum operating temperature of 125°C. Ensure proper thermal management by providing adequate airflow, using thermal vias, and keeping the component away from heat sources.
The SRF of the PM1812-221J-RC is not explicitly stated in the datasheet. However, it can be estimated using the inductor's inductance and capacitance values. For a more accurate calculation, consult with a Bourns application engineer or use a simulation tool like LTspice.
While the PM1812-221J-RC is a high-quality component, it may not meet the specific requirements for high-reliability or aerospace applications. Consult with Bourns or a qualified engineer to determine the suitability of this component for your specific application.
The saturation current of the PM1812-221J-RC can be determined by consulting the inductor's datasheet and using the specified inductance and DC resistance values. You can also use a simulation tool or consult with a Bourns application engineer for guidance.
