CM05RB03

Overview

The CM05RB03 is a leaded common mode choke coil from the Taiyo Yuden CM05RB series, designed for DC and signal lines. It features a 2-line configuration with a typical common mode impedance of 1400 Ohms at 100 MHz and a minimum common mode inductance of 15 uH. The component has a maximum DC resistance (DCR) of 60 mOhm and supports a current rating of 1.5 A. Its case size measures 9.5 x 5.5 mm. The device is currently discontinued.

Feature Summary

• Provides effective noise suppression for DC and signal lines through high common mode impedance.
• Features a leaded package suitable for through-hole mounting applications.

Applications

• Noise filtering for DC power circuits
• Signal line protection against electromagnetic interference

Procurement Notes

This component is officially listed as discontinued by the manufacturer. Verification of availability should focus on surplus or secondary market sources rather than standard distribution channels. Ensure that any replacement parts meet the original electrical specifications, particularly the 1400 Ohm impedance at 100 MHz and 1.5 A current rating, to maintain circuit integrity.

Selection Notes

Select this part only if legacy compatibility is required, as it is no longer in production. For new designs, consider alternative common mode chokes from the same manufacturer that offer similar impedance and current ratings but are currently active. Verify that the leaded form factor fits the target PCB layout constraints.

Part Context

The CM05RB03 belongs to the CM05RB series of common mode choke coils manufactured by Taiyo Yuden. This series is characterized by its leaded construction and application in filtering noise for both DC and signal lines. The specific model provides a balance of high impedance and moderate current handling within a compact 9.5 x 5.5 mm case.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation due to the discontinued status.
