Overview
The B82793C0206N265 is a surface-mount common-mode choke from the EPCOS (TDK) B82793C0/S0 series. It features a ferrite core and LCP case with bifilar winding construction. The component has a rated inductance of 20 mH at 100 kHz, a maximum DC resistance of 1.8 Ohms, and a rated current of 100 mA. It supports a rated voltage of 42 V AC or 80 V DC and operates within a temperature range up to +60 °C.
Feature Summary
- Suppresses asymmetrical interference coupled into data lines while allowing high-frequency data signals to pass unaffectedly.
- Constructed with a ferrite core and UL 94 V-0 rated LCP case using silicone potting for durability.
- Qualified to AEC-Q200 standards for automotive reliability applications.
Applications
- Data line filtering in automotive electronics
- Signal line protection in industrial equipment
- EMC suppression for communication interfaces
Procurement Notes
Verify the specific suffix N265 against official TDK-EPCOS documentation to confirm packaging details and exact tolerance specifications. Ensure compatibility with reflow soldering profiles as the component is designed for surface mount technology. Cross-reference the rated current and inductance values with system requirements to prevent saturation during operation.
Selection Notes
Select this component when asymmetric noise suppression is required on data lines without attenuating the signal. The 20 mH inductance provides significant filtering for lower frequency interference. Verify that the 100 mA current rating meets the operational load and that the 1.8 Ohm DC resistance does not cause excessive voltage drop in the circuit design.
Part Context
This part belongs to the B82793C0/S0 family of data and signal line chokes manufactured by EPCOS (now TDK Electronics). The series offers various inductance values ranging from 0.005 mH to 47 mH with rated currents between 100 mA and 1200 mA. These components are designed for compact surface-mount applications requiring reliable EMC performance.
Replacement Considerations
Check for direct substitutes within the B82793C0 series with similar inductance and current ratings. Verify pinout compatibility and physical dimensions before substituting with other manufacturers' common-mode chokes to ensure mechanical fit and electrical equivalence.
