B82747S4203A020

Overview

The B82747S4203A020 is a current-compensated ring core choke manufactured by EPCOS (TDK Electronics). It features a rated current of 20A and an inductance of 1.3 mH at 10 kHz. The component has a maximum DC resistance of 5.2 mOhm. Its physical dimensions are 59.00 mm in length, 28.00 mm in width, and 60.00 mm in height. This power line choke is designed for general-purpose applications requiring effective common-mode noise suppression.

Feature Summary

• Current-compensated ring core design for efficient magnetic field cancellation
• High rated current capacity of 20A for robust power line handling
• Low DC resistance to minimize power loss and heat generation

Applications

• Power line filtering in industrial equipment
• Common mode noise suppression in AC power inputs
• Electromagnetic compatibility enhancement in power supplies

Procurement Notes

Verify the exact ordering code B82747S4203A020 against manufacturer documentation to ensure correct specifications. Confirm that the 20A rated current and 1.3 mH inductance meet your circuit requirements. Check for RoHS compliance status as indicated in official datasheets. Ensure mechanical fit within the 59x28x60 mm envelope. Validate supplier authenticity through authorized TDK Electronics channels.

Selection Notes

Select this component when high current handling up to 20A is required alongside significant common-mode noise attenuation. The low DCR makes it suitable for efficiency-sensitive power stages. Consider the physical size constraints given its 60mm height. Compare with other B82747 series variants if different inductance or current ratings are needed. Ensure the operating temperature range aligns with your application environment.
