CM04RC04T

Overview

The CM04RC04T is a two-line surface-mount common mode choke coil manufactured by Taiyo Yuden. It features a typical impedance of 900 Ohms at 20 MHz and a maximum DC resistance of 100 milliohms. The component supports a rated current of 1.3 Amperes and operates within a temperature range of -25°C to +105°C. Its physical dimensions are 9.00 mm in length, 5.20 mm in width, with a maximum height of 4.40 mm. The device is designed for filtering both power and signal lines.

Feature Summary

• Provides effective noise suppression for differential signals and power rails through high common mode impedance.
• Supports high current handling capabilities suitable for demanding power line applications.
• Utilizes a compact surface mount package design optimized for automated assembly processes.

Applications

• Filtering noise on DC power supply lines
• Signal integrity protection for data transmission lines
• Electromagnetic interference suppression in portable electronic devices

Procurement Notes

Verify the specific manufacturing date code against project requirements as this component is listed as discontinued. Confirm that the 900 Ohm impedance at 20 MHz meets the target noise frequency spectrum. Ensure the 1.3A current rating aligns with peak operational loads to prevent saturation. Check for available alternative components from the same manufacturer series if long-term supply stability is required.

Selection Notes

Select this component when a balance between high current capacity and moderate impedance is required for low-frequency noise filtering. The 100 milliohm DC resistance minimizes voltage drop across the filter. Consider the 9.0x5.2 mm footprint constraints during PCB layout. Evaluate thermal performance under continuous load conditions given the 105°C maximum operating temperature limit.

Part Context

This part belongs to the CM04 series of common mode chokes from Taiyo Yuden. The series offers various impedance and current ratings tailored for different filtering needs.
