Overview
The Bourns 7101-RC is a leaded common mode choke from the 7100 series, designed for power line filtering. It features an inductance of 510 µH at 1 kHz and supports a maximum DC current of 1 A with a maximum DC resistance of 40 mOhms. The component utilizes a ferrite core and radial termination style for PCB mounting. It operates within a temperature range of -55°C to +105°C and provides a dielectric strength of 1000 Vrms. Physical dimensions include a diameter of 0.6 inches and a width of 0.45 inches.
Feature Summary
- Dual winding configuration for effective common mode noise suppression
- High dielectric strength of 1000 Vrms for enhanced isolation safety
- Low radiation design suitable for sensitive electronic environments
- Mounted on VW-1 rated headers for flame retardant stability
Applications
- Power supply input filtering
- EMI suppression in industrial equipment
- Signal integrity protection in communication devices
Procurement Notes
Verify the specific suffix and manufacturing date code against the latest Bourns datasheet to ensure compliance with current RoHS directives and material declarations. Confirm that the radial lead spacing matches your PCB footprint requirements prior to ordering. Cross-reference the part number with authorized distributors to validate authenticity and traceability documentation.
Selection Notes
Select this component when high inductance values are required for low-frequency noise attenuation in power lines. The 1 A current rating makes it suitable for moderate power applications where space constraints allow for through-hole mounting. Consider the unshielded nature of the design regarding potential magnetic interference with nearby components during layout.
Part Context
This component belongs to the Bourns 7100 series of common mode chokes, which offers various inductance options for different filtering needs. The series is characterized by its robust ferrite core construction and leaded package format, providing reliable performance in demanding industrial and commercial environments.
Replacement Considerations
Consult official substitution lists for equivalent inductance and current ratings. Verify mechanical compatibility including lead spacing and body dimensions before replacing.
