8117-RC

Overview

The Bourns Inc. 8117-RC is a through-hole common mode choke designed for two-line applications. It features a minimum inductance of 36 mH measured at 1 kHz and supports a current rating of 2.9 A. The component exhibits a direct current resistance (DCR) of 300 mOhm. Physically, it utilizes a non-shielded construction with dimensions of approximately 1.55 inches in length, 0.80 inches in width, and 0.90 inches in height. The device is RoHS compliant and supplied in bulk packaging.

Feature Summary

• Provides common mode noise suppression for two-line circuits
• Supports high current handling up to 2.9 Amperes
• Features through-hole mounting for robust PCB integration
• Constructed with non-shielded design for standard EMI filtering

Applications

• Consumer electronics power supply filtering
• Industrial equipment signal integrity protection
• Telecommunications line noise reduction
• Office machinery circuit interference suppression

Procurement Notes

Verify the specific suffix requirements against the official Bourns datasheet to ensure compatibility with environmental standards and packaging preferences. Confirm that the 36 mH minimum inductance meets the target application's frequency response needs. Check for any lead-free compliance documentation if required by regional regulations. Ensure the through-hole footprint matches the intended PCB layout constraints before finalizing orders.

Selection Notes

Select this component when a high inductance value of 36 mH is required for effective low-frequency noise attenuation. The 2.9 A current rating makes it suitable for applications with moderate to high line currents. Consider the non-shielded nature if magnetic coupling with nearby components must be managed. Evaluate the physical dimensions to ensure adequate clearance on the printed circuit board assembly.

Part Context

This component belongs to the Bourns 8117 series of common mode chokes, which are engineered for general-purpose electromagnetic interference suppression. The series offers various inductance values and current ratings to suit different line configurations. As part of Bourns' passive component portfolio, these inductors support reliability standards required for industrial and consumer markets.

Replacement Considerations

Consult the official Bourns cross-reference guide for verified substitutes. Potential alternatives within the same series include variants with different inductance or current ratings, such as the 8118-RC, provided they meet the electrical and mechanical requirements of the design.
