B82502WC5

Overview

The B82502WC5 is a two-line through-hole common mode choke manufactured by EPCOS (TDK Electronics). It features a fixed inductance of 15 mH and supports a maximum current rating of 500 mA. The component exhibits a typical DC resistance of 8.5 Ohms. Designed for power line filtering applications, it operates within a temperature range of -40°C to +125°C.

Feature Summary

• Provides effective attenuation of common mode noise in dual-line circuits
• Utilizes a robust construction suitable for high-temperature environments up to 125°C
• Offers reliable electromagnetic interference suppression for sensitive electronic loads

Applications

• Power supply input filtering
• Data processing equipment noise reduction
• Industrial control system signal integrity protection

Procurement Notes

Verify the specific ordering suffix against the official EPCOS/TDK datasheet to ensure compatibility with required lead lengths and terminal configurations. Confirm that the 500 mA current rating meets the operational requirements of the target circuit to prevent saturation or excessive heating during continuous use.

Selection Notes

Select this component when a 15 mH inductance value is required for common mode noise suppression in low-current applications. Ensure the PCB layout accommodates the through-hole mounting style and provides adequate clearance for the physical dimensions of the cylindrical package.

Part Context

This component belongs to the B82502 series of common mode chokes from EPCOS. These devices are engineered for general-purpose electromagnetic compatibility (EMC) filtering in consumer and industrial electronics, providing a balance between performance and cost-effectiveness for standard power line applications.

Replacement Considerations

Consult the official EPCOS replacement guide for direct equivalents. Verify that any substitute part matches the 15 mH inductance, 500 mA current rating, and 8.5 Ohm DC resistance specifications to maintain circuit performance.
