The component has a typical DC resistance of 8.4 mOhm and utilizes a through-hole mounting type. Its physical dimensions are 52.00 mm in maximum length, with a vertical package configuration containing four pins. The device operates within a temperature range of -40°C to 125°C and is intended for filtering noise on two-line power circuits.

Feature Summary

• Current-compensated ring core design for effective common mode noise suppression
• Dual-line filtering capability for AC power line applications
• Through-hole mounting for robust mechanical integration

Applications

• Power line EMI filtering
• Industrial equipment power supplies
• Consumer electronics power inputs

Procurement Notes

Verify the specific suffix N020 against official TDK documentation to confirm pin configuration and tolerance specifications. Ensure the required inductance value of 3.3 mH at the standard test frequency aligns with the circuit design requirements. Confirm that the 12 A rated current capacity meets the operational load demands without saturation. Check compatibility with the specified through-hole mounting style and PCB layout constraints.

Selection Notes

Select this component when high current handling up to 12 A is required alongside significant inductance for power line filtering. The current-compensated architecture minimizes magnetic field interference, making it suitable for sensitive environments. Consider the vertical package profile and through-hole termination if surface-mount alternatives are unsuitable for the mechanical stress or thermal management needs of the application.

Part Context

This part belongs to the B82726 series of current-compensated ring core chokes from EPCOS (TDK). These components are engineered for power line filtering, offering high current ratings and stable inductance characteristics. The series is widely used in industrial and consumer applications where reliable electromagnetic interference suppression is critical for system stability and compliance.

Replacement Considerations

Consult the official TDK replacement guide for direct substitutes within the B82726 series. Verify that any alternative part matches the 3.3 mH inductance, 12 A current rating, and 8.4 mOhm DCR specifications. Ensure the replacement maintains the same through-hole package and operating temperature range.
