Procurement Notes

Verify the specific datasheet version and manufacturer documentation before finalizing design-in decisions. Confirm that the +100%/-10% inductance tolerance aligns with circuit requirements. Ensure the 250 mA rated current meets the application's load demands. Check for any phaseout status or end-of-life notifications directly from Taiyo Yuden official channels prior to procurement.

Selection Notes

Select this component when through-hole assembly is required for AC line filtering. Consider the 8 mH inductance value for low-frequency noise attenuation. Evaluate the 4 Ω DC resistance impact on voltage drop. Verify compatibility with the -25°C to +105°C operating environment. Compare physical footprint against available PCB space constraints.
