Overview
The B82623G0001A011 is a ring core choke manufactured by EPCOS (TDK Electronics). It features an iron powder core and provides an inductance of 33 µH with a rated current of 3 A. The component is designed for through-hole mounting and supports a rated voltage of 250 V AC or 350 V DC. It includes two windings and is RoHS compliant.
Feature Summary
- Utilizes an iron powder ring core for stable magnetic performance
- Designed as a common mode choke for noise suppression
- Supports high current ratings suitable for power applications
Applications
- Power Factor Correction (PFC) circuits
- Common mode noise filtering in power supplies
- Electromagnetic interference suppression in industrial electronics
Procurement Notes
Verify the specific suffix against the official TDK datasheet to ensure correct inductance and current ratings. Confirm that the through-hole package matches your PCB footprint requirements. Check for RoHS compliance status if required by your manufacturing standards. Ensure the rated temperature and voltage specifications align with your circuit's operational limits before procurement.
Selection Notes
Select this component when a high-current common mode choke with an iron powder core is required. The 33 µH inductance and 3 A rating make it suitable for PFC stages. Consider the through-hole mounting style for mechanical stability. Verify that the 250 V AC / 350 V DC voltage ratings meet your system's isolation needs.
Part Context
This part belongs to the B82623 series of ring core chokes from EPCOS (TDK). These components are widely used in automotive and industrial applications for electromagnetic compatibility. The iron powder core material offers good saturation characteristics, making them distinct from ferrite-based alternatives in high-current scenarios.
Replacement Considerations
Consult the official TDK replacement guide for verified substitutes. Cross-reference inductance, current rating, and physical dimensions. Ensure any alternative maintains the same core material properties and mounting style for direct compatibility.
