Overview
The Bourns 8103-RC is a through-hole common mode choke from the 8100 Series, designed for EMI suppression. It features a single-layer wound construction with an inductance of 1 mH and a current rating of 4.8 A. The component has a maximum DC resistance of 22 mΩ and operates within a temperature range of -55°C to 105°C. It provides a dielectric strength of 1500 Vrms and is RoHS compliant.
Feature Summary
- Single-layer wound construction for effective EMI suppression across a wide frequency spectrum
- High dielectric strength capability ensuring robust insulation performance
- Through-hole mounting configuration suitable for standard PCB assembly
Applications
- General electronic equipment requiring common mode noise filtering
- Power supply input stages for EMI reduction
- Signal lines requiring interference suppression
Procurement Notes
Verify the specific suffix designation against official Bourns documentation to confirm compliance status and physical dimensions. Ensure the procurement specification matches the required inductance and current ratings for the target application circuit. Cross-reference the manufacturer part number with the latest datasheet to confirm availability of the lead-free variant.
Selection Notes
Select this component when a high-current common mode choke with significant inductance is required for through-hole applications. The 4.8 A rating supports substantial load currents while maintaining low DC resistance. Consider the operating temperature range and physical size constraints during PCB layout design to ensure adequate clearance and thermal management.
Part Context
This component belongs to the Bourns 8100 Series of common mode chokes. The series offers various inductance and current combinations for different filtering requirements. The 8103-RC specifically addresses applications needing 1 mH inductance at 4.8 A, providing a balance between noise suppression efficiency and power handling capacity in a standard through-hole package.
Replacement Considerations
The non-compliant variant 8103 shares identical electrical specifications but lacks RoHS compliance. Verify regulatory requirements before substitution. No other direct substitutes are confirmed in the provided data.
