Overview
The Bourns 7114-RC is a through-hole common mode choke featuring dual windings on a ferrite core. It provides a dual inductance of 2550 µH at 1 kHz and supports a maximum current rating of 2 A with a DC resistance of 85 mΩ. The component measures 22.86 mm in diameter by 16.51 mm in width, offering high inductance and low radiation characteristics suitable for EMI suppression.
Feature Summary
- Dual winding construction for effective noise cancellation
- High dielectric strength rated at 1000 Vrms
- Mounted on a VW-1 rated header for safety compliance
- Low radiation design to minimize electromagnetic interference
Applications
- Common mode EMI filtering in electronic circuits
- Power supply input stages requiring noise suppression
- Signal lines needing differential mode interference reduction
Procurement Notes
Verify the specific datasheet version for the 7114-RC to confirm mechanical dimensions and electrical tolerances match your design requirements. Ensure compatibility with your assembly process regarding the through-hole mounting style and header configuration. Cross-reference the 2 A current rating against your peak load conditions to prevent saturation.
Selection Notes
Select this component when high inductance values are required for low-frequency noise attenuation. The 2 A current capacity suits moderate power applications. Consider the physical footprint of approximately 22.86 mm diameter for board space constraints. Verify that the ferrite core material aligns with your operating frequency range for optimal performance.
