Overview
The B82502WC8 is a fixed inductor from the EPCOS B82502W series, classified as a common mode choke. It features a rectangular plastic case with resin potting and horizontal mounting via four PC pins. The component has a rated inductance of 3.3 mH and handles a maximum DC current of 1 A. Its typical DC resistance is 1.9 Ohms. The device supports a rated AC voltage of 500 V and a DC voltage rating of 600 V.
Feature Summary
- Constructed with an I-core design housed in a rectangular plastic case with resin potting for durability.
- Designed for through-hole mounting using four horizontal PC pins to secure the component on printed circuit boards.
Applications
- Power line filtering in electronic equipment
- EMI suppression in single-phase power supplies
- Common mode noise reduction in signal lines
Procurement Notes
Verify the specific suffix WC8 against official EPCOS documentation to confirm pin configuration and tolerance. Ensure the selected variant matches the required 3.3 mH inductance and 1 A current rating for your circuit design. Cross-reference the datasheet for exact dimensional constraints and thermal performance limits before finalizing procurement.
Selection Notes
Select this component when a 3.3 mH common mode choke is required for 500 V AC applications. Confirm that the 1 A current rating meets the operational load requirements. Verify that the through-hole package style fits the available PCB layout space and mounting orientation constraints.
Part Context
This part belongs to the B82502W series of power line chokes manufactured by EPCOS, now part of TDK Electronics. The series offers various inductance values and current ratings within a standardized rectangular housing. These components are designed for robust performance in industrial and consumer electronics environments requiring reliable electromagnetic interference suppression.
Replacement Considerations
Consult official EPCOS substitution guides for compatible alternatives. Verify that any replacement maintains the same 3.3 mH inductance, 1 A current handling, and 500 V AC voltage rating. Ensure physical dimensions and pin configurations match to avoid PCB redesign.
