8104

Overview

The Bourns Inc. 8104 is a through-hole common mode choke designed for electromagnetic interference suppression. It features a 10 mH inductance and a 2.4 A current rating. The DC resistance is typically 170 mOhm. The component operates within a temperature range of -55°C to 105°C.

Feature Summary

• Provides common mode noise filtering for differential signal lines
• Utilizes through-hole mounting for secure PCB attachment
• Constructed with lead-free materials compliant with environmental standards

Applications

• Differential data line protection in industrial equipment
• EMI suppression in consumer electronics power supplies
• Signal integrity enhancement in communication interfaces

Procurement Notes

Verify the specific suffix (e.g., RC) against the required datasheet revision. Confirm package dimensions and pin compatibility with the target PCB footprint. Ensure the operating temperature range meets system requirements. Check for RoHS compliance documentation if mandated by regional regulations.

Selection Notes

Select based on the required inductance value and maximum continuous current. Evaluate the DC resistance impact on circuit efficiency. Consider the physical size constraints for through-hole placement. Verify that the core material suits the frequency range of the noise to be suppressed.

Part Context

This component belongs to the Bourns 8100 Series of common mode inductors. These components are engineered for general-purpose EMI filtering applications. The series offers various inductance values and current ratings to suit different circuit protection needs.

Replacement Considerations

The 8104-RC is a verified equivalent variant from the same manufacturer. Ensure substitute parts match the 10 mH inductance and 2.4 A current rating. Verify identical through-hole package dimensions for direct replacement.
