8115

Overview

The Bourns Inc. 8115-RC is a through-hole common mode choke designed for two-line applications. It features an inductance of 1.2 mH measured at 1 kHz and supports a current rating of 16 A. The component has a DC resistance (DCR) of 6 mOhm. Its physical dimensions are characterized by a pitch of 22.86 x 15.24 mm. The unit offers a dielectric strength of 1500 Vrms, ensuring robust isolation capabilities for industrial and commercial electronic circuits.

Feature Summary

• Provides effective common mode noise suppression for dual-line configurations
• Engineered with high current handling capacity for power line stability
• Features low DC resistance to minimize signal loss and power dissipation
• Constructed with high dielectric strength for enhanced electrical isolation

Applications

• Industrial control systems requiring EMI filtering
• Commercial equipment power supply inputs
• Telecommunications infrastructure signal protection
• Automotive electronics noise reduction

Procurement Notes

Verify the specific suffix designation when ordering, as variations may exist within the product family. Confirm that the through-hole mounting style aligns with your PCB design requirements. Ensure the 16 A current rating meets the operational demands of your circuit to prevent saturation. Check for RoHS compliance status if required by your manufacturing standards. Validate the package dimensions against your assembly constraints before finalizing procurement.

Selection Notes

Select this component when high current handling is critical alongside common mode noise attenuation. The 1.2 mH inductance value is suitable for standard power line filtering applications. Consider the through-hole format if automated surface-mount assembly is not available or if mechanical robustness is prioritized. Evaluate the 6 mOhm DCR to ensure it fits within your system's efficiency targets. Compare against alternative inductors if lower current ratings suffice for your specific use case.

Part Context

This component belongs to Bourns' common mode inductor series, which focuses on electromagnetic interference suppression. These inductors are widely used in environments where electrical noise can disrupt sensitive electronics. The 8115 series specifically targets applications requiring durable, high-current solutions. Bourns designs these components to meet rigorous reliability standards for industrial and commercial markets.

Replacement Considerations

Consult official Bourns documentation for direct cross-reference part numbers. Verify that any substitute matches the 1.2 mH inductance and 16 A current rating exactly. Ensure the replacement maintains the same through-hole footprint and pin configuration. Confirm equivalent dielectric strength and DC resistance values to preserve circuit performance.
