WE-PD2SR Self-Centering Shielded Power Inductors Würth Elektronik WE-PD2SR Self-Centering Shielded Power Inductors are magnetically shielded and feature a low leakage field and stable inductance current due to the self-centering shielding ring construction. They are a pin-to-pin replacement in an EMI-optimized design for this unshielded family compatible with the PD2 size 7850 and are ready to solder and test. The WE-PD2SR series is trimmed to have high saturation currents for its compact size of 7.8mm x 7.8mm and has a wide range of different inductance values available. The recommended solder profile is reflow. The operating temperature range is -40°C to +125°C.
