B82725A2143N020

Overview

The B82725A2143N020 is a current-compensated ring core double choke from the EPCOS B82725A series, designed for power line filtering applications. It features a nominal inductance of 1.2 mH and supports a continuous current rating of 14 A. The component operates within an ambient temperature range of -40°C to +125°C and utilizes a horizontal through-hole mounting configuration with four pins. Its physical dimensions are 44.00 mm in length, 42.40 mm in width, and a maximum height of 25.00 mm.

Feature Summary

• Current-compensated ring core construction for effective common mode noise suppression
• Designed specifically for power line filtering in two-line configurations
• Capable of handling high continuous currents up to 14 A

Applications

• Power line filtering for industrial equipment
• EMI suppression in AC mains input stages
• Filtering solutions for IT mains supply systems

Procurement Notes

Verify the specific suffix N020 against official EPCOS documentation to confirm pinout orientation and packaging details. Ensure that the 14 A current rating aligns with your thermal management design, as self-heating at high loads may affect performance. Cross-reference the 1.2 mH inductance value with your circuit requirements to guarantee adequate attenuation characteristics for your target frequency range.

Selection Notes

Select this component when high current capacity is required alongside significant inductance for power line applications. The 1.2 mH value offers a balance between filtering effectiveness and size constraints compared to higher inductance variants. Consider the through-hole package for robust mechanical stability in environments subject to vibration or thermal cycling, ensuring compatibility with standard PCB layouts for 4-pin horizontal mounts.

Part Context

This part belongs to the B82725A series of power line chokes manufactured by EPCOS (now TDK). The series covers a wide range of inductances from 0.56 mH to 82 mH and currents from 1 A to 16 A. These components are engineered for reliability in demanding industrial and automotive environments, providing consistent performance across the specified operating temperature range.

Replacement Considerations

Check for other B82725A variants with similar inductance and current ratings if exact matches are unavailable. Verify that any substitute maintains the same 4-pin horizontal through-hole footprint and dimensional constraints to ensure board compatibility without redesign.
