Procurement Notes
Verify the specific part number RB6522-50-0M3 against official Schaffner documentation to confirm electrical ratings and physical dimensions. Ensure compatibility with PCB layout requirements regarding lead pitch and hole size. Check for RoHS compliance status if required by project specifications. Confirm voltage ratings match the application's peak operational conditions.
Selection Notes
Select this component when high current capacity and low DC resistance are critical for minimizing power loss in power line filtering. The radial package suits through-hole mounting where mechanical stability is needed. Consider the 250 µH inductance value for the target frequency range of noise attenuation. Verify that the 1000 V rating exceeds the system's maximum operating voltage.
