Overview
The B82721A2602N020 is a current-compensated ring core double choke manufactured by EPCOS (TDK Electronics). It features a rated voltage of 250 V AC and a nominal inductance of 200 µH. The component supports a maximum DC current of 6 A with a maximum DC resistance of 280 mΩ. It operates within a temperature range of -40 °C to +125 °C. The physical dimensions are 17.9 mm in length, 17.3 mm in width, and 12.6 mm in height. Termination style is radial through-hole.
Feature Summary
- High resonance frequency achieved through special winding technique
- Approximately 1% stray inductance for symmetrical interference suppression
- Suitable for wave soldering processes
- Complies with EN 60938-2 (VDE 0565-2) design standards
Applications
- Suppression of common-mode interferences
- Electronic ballasts in lamps
- Switch-mode power supplies
Procurement Notes
Verify the specific suffix N020 against official TDK/EPCOS documentation to confirm terminal configuration and packaging details. Ensure the selected variant matches the required thermal and electrical ratings for the target application environment. Cross-reference approval agencies such as ENEC, UR, and VDE if regulatory compliance is mandatory for the end product.
Selection Notes
Select this component when designing circuits requiring high current handling up to 6 A with low stray inductance for effective common-mode noise reduction. The wide operating temperature range makes it suitable for industrial and automotive environments. Consider the radial leaded package for through-hole mounting constraints and wave soldering compatibility during assembly.
Part Context
This part belongs to the B82721A series of current-compensated ring core double chokes. The series offers a broad range of inductance values from 0.2 mH to 47 mH and rated currents from 0.3 A to 6 A. These components are designed for power line applications, providing robust electromagnetic interference filtering in compact form factors.
Replacement Considerations
Consult official TDK/EPCOS substitution guides for verified alternatives. Generic equivalents may not match the specific 1% stray inductance or high resonance frequency characteristics.
