CM04RC05T

Overview

The CM04RC05T is a four-line surface mount common mode choke coil manufactured by Taiyo Yuden. It features an impedance of 800 Ohms at 100 MHz and a maximum DC resistance of 200 milliohms. The component supports a rated current of 500 mA with a DC voltage rating of 50 V. Its physical dimensions are 9.80 mm in length, 9.00 mm in width, and a maximum height of 4.10 mm. The device operates within a temperature range of -25°C to +105°C.

Feature Summary

• Four-line configuration for simultaneous suppression across multiple signal or power paths
• High impedance characteristics effective for noise reduction at 100 MHz
• Low DC resistance design minimizes insertion loss in high-current applications

Applications

• Noise suppression on DC power lines
• Signal line filtering in electronic circuits
• Common mode interference mitigation in multi-conductor cables

Procurement Notes

Verify component status as discontinued through official manufacturer channels before integration. Confirm availability of alternative sources if production continuity is required. Ensure compatibility with existing PCB footprints and thermal management requirements during the transition phase.

Selection Notes

Select this component when four independent lines require common mode noise suppression in a compact surface mount package. Evaluate the 500 mA current rating against peak load requirements. Consider the 800 Ohm impedance specification relative to target noise frequencies. Verify that the 50 V DC rating exceeds the operating voltage margin.

Part Context

This part belongs to the CM04 series of common mode chokes designed for surface mount technology. It serves as a specialized filter for managing electromagnetic interference in dense circuit layouts. The four-line architecture distinguishes it from standard two-line variants, offering integrated filtering for complex data or power buses.
