Procurement Notes

Verify the specific suffix N021 against official TDK/EPCOS documentation to confirm pinout orientation and tolerance class. Ensure the selected variant matches the required 37 mH inductance and 1.4 A current rating for the target circuit. Cross-reference the RoHS compliance status with the latest manufacturer declarations before finalizing procurement orders.

Selection Notes

Select this component when high inductance values are required in a compact through-hole form factor. The current-compensated architecture makes it suitable for applications where common-mode noise suppression is critical. Verify that the physical footprint fits the PCB layout constraints and that the operating temperature range meets the environmental requirements of the end device.
