Overview
The B82721S0272T040 is a surface-mount common-mode choke manufactured by EPCOS (TDK Electronics). It features a dual-line configuration with a nominal inductance of 3 mH at 10 kHz. The component supports a maximum rated current of 2.7 A and exhibits a DC resistance of 65 mOhm. Designed for data and signal line applications, it operates within a temperature range of -40 °C to +125 °C.
Feature Summary
- Provides effective common-mode noise suppression for data and signal lines
- Surface-mount construction enables automated PCB assembly
- Dual-line design handles differential signals efficiently
Applications
- Data and signal line filtering
- Common-mode noise suppression in electronic circuits
- Power line chokes for low-current applications
Procurement Notes
Verify the complete ordering code B82721S0272T040 against official TDK/EPCOS documentation to confirm specifications. Ensure compatibility with surface-mount assembly processes and thermal requirements. Confirm that the 2.7 A current rating and 3 mH inductance meet the specific circuit design needs before procurement.
Selection Notes
Select this component for applications requiring common-mode filtering on data or signal lines where surface-mount technology is preferred. The 2.7 A current rating and 65 mOhm DC resistance are suitable for low-to-medium current signal paths. Verify that the operating temperature range of -40 °C to +125 °C aligns with the environmental conditions of the target application.
Part Context
This component belongs to the B82721 series of common-mode chokes from EPCOS (TDK Electronics). The series includes various inductance and current ratings designed for different filtering requirements. The 'S' suffix typically denotes surface-mount packaging, while 'T040' indicates tape-and-reel packaging for automated handling.
Replacement Considerations
Consult official TDK/EPCOS substitution guides for verified alternatives. Ensure any replacement part matches the 3 mH inductance, 2.7 A current rating, and surface-mount package dimensions. Verify that the substitute component meets the same electrical and thermal performance standards.
