7402-RC

Overview

The Bourns 7402-RC is a through-hole common mode choke designed for EMI filtering in two-line circuits. It provides an inductance of 600 µH at 1 kHz and supports a maximum current rating of 2.8 A. The component features a low DC resistance (DCR) of 46 mΩ and is rated for AC voltages up to 250 V. This dual-line filter is suitable for applications requiring robust noise suppression in power and signal lines.

Feature Summary

• Dual-line configuration for effective common mode noise attenuation
• Through-hole mounting for secure mechanical attachment
• Low DC resistance to minimize power loss during operation

Applications

• EMI filtering in consumer electronics power supplies
• Noise suppression in industrial control systems
• Signal line protection in telecommunications equipment

Procurement Notes

Verify the specific suffix and packaging format with the manufacturer or authorized distributor, as standard retail listings may not reflect bulk availability or specific reel/tape configurations. Confirm RoHS compliance status and lead-free requirements against the latest official datasheet revision before finalizing procurement orders.

Selection Notes

Select this component when a 600 µH inductance at 1 kHz is required for common mode noise reduction in 2.8 A circuits. Ensure the operating voltage does not exceed 250 V AC. Consider the through-hole package constraints and verify that the 46 mΩ DCR meets the system's efficiency and thermal management requirements.

Part Context

This part belongs to Bourns' common mode choke family, which offers various inductance values and current ratings for EMI suppression. The 7402-RC specifically targets applications needing moderate inductance with high current handling capabilities in a through-hole form factor.

Replacement Considerations

Consult official substitution guides for equivalent inductance and current ratings. Verify pin compatibility and physical dimensions before replacing.
