Overview
The Bourns 7108-RC is a two-line common mode choke designed for filtering differential-mode and common-mode noise in power supply and signal lines. It features dual windings with an inductance of 1.7 mH at 1 kHz and supports a current capacity of 2A. The component has a maximum DC resistance of 60 mOhms and offers a dielectric strength of 1000Vrms. It is mounted on a VW-1 rated header using through-hole technology.
Feature Summary
- Dual winding construction for effective noise suppression
- Low radiation characteristics for signal integrity
- High current capacity suitable for demanding applications
- Dielectric strength of 1000Vrms for isolation safety
Applications
- Power supply line filtering
- Signal line noise reduction
- Differential-mode and common-mode interference suppression
Procurement Notes
Verify the specific ordering suffix to ensure the correct package variant, as suffixes may indicate differences in base or mounting configuration. Confirm that the 1000Vrms dielectric strength meets your isolation requirements. Ensure the through-hole footprint matches your PCB design constraints before finalizing procurement.
Selection Notes
Select this component when high inductance and low DC resistance are required for noise filtering in two-line circuits. The 2A current rating and 105C maximum operating temperature make it suitable for industrial and consumer electronics. Verify that the vertical pin configuration fits your assembly process.
Part Context
This component belongs to Bourns' common mode EMI choke series, which provides solutions for electromagnetic interference suppression. The 7108-RC utilizes a dual-winding design to handle both differential and common mode signals effectively. It is part of a broader portfolio of passive components used in power and signal conditioning applications.
Replacement Considerations
Check for direct substitutes within the same series, such as the 7109-RC, which shares similar form factors but may differ in inductance values. Ensure any replacement maintains the 2A current rating and 1000Vrms dielectric strength to preserve circuit safety and performance standards.
