Overview
The B82721S0562A030 is a surface-mount common mode choke manufactured by EPCOS - TDK Electronics. It features a current-compensated ring core design with a ferrite core and polycarbonate case. The component provides an inductance of 768 µH and supports a maximum current of 5.6 A. It has a DC resistance (DCR) of 18 mOhm. The device utilizes sector winding for high resonance frequency and low stray inductance.
Feature Summary
- Current-compensated ring core double choke construction
- High resonance frequency due to special sector winding technique
- Flame-retardant case and potting compliant with UL 94 V-0 standards
Applications
- Data and signal line chokes
- Common-mode filters
- Power line interference suppression
Procurement Notes
Verify the specific ordering code against official TDK-EPC documentation to ensure correct inductance and current ratings. Confirm package type and pin configuration match the target PCB layout. Check for RoHS compliance status if required by project specifications. Ensure storage conditions adhere to manufacturer guidelines to maintain component integrity prior to assembly.
Selection Notes
Select this component for applications requiring symmetrical interference suppression with low stray inductance. The 5.6 A current rating suits moderate power data lines. The surface mount format facilitates automated assembly. Evaluate thermal performance under load to ensure the 18 mOhm DCR does not cause excessive heating in dense layouts.
Part Context
This part belongs to the B82721 series of current-compensated ring core double chokes. These components are designed for power lines and signal integrity protection. The series offers various inductance values tailored for different noise filtering requirements while maintaining compact surface-mount dimensions.
Replacement Considerations
Consult official cross-reference lists for verified substitutes. Ensure replacement parts match the 768 µH inductance, 5.6 A current rating, and 18 mOhm DCR specifications. Verify mechanical footprint compatibility before substitution.
