RGCMF1210900H3T

Common Mode Chokes Overview

The RGCMF1210900H3T is a surface-mount common mode choke manufactured by Walsin Technology Corporation. It features a 1210 (3225 metric) package with dimensions of 3.2 mm length, 2.5 mm width, and 0.6 mm height. The component provides a nominal impedance of 90 Ohms at 100 MHz and supports a current rating of 300 mA. Its DC resistance is specified as 1 Ohm. The device is unshielded and designed for high-frequency noise suppression in electronic circuits.

Common Mode Chokes Feature Summary

• Provides effective common mode noise attenuation for differential signal lines
• Utilizes a compact 1210 surface-mount footprint for space-constrained designs
• Constructed without shielding to minimize size and profile

Common Mode Chokes Applications

• High-speed data interface protection
• Signal line noise filtering
• Common mode interference suppression in compact electronics

Common Mode Chokes Procurement Notes

Verify the specific impedance tolerance and current derating curves against the official Walsin datasheet before finalizing circuit designs. Confirm that the unshielded construction meets the electromagnetic compatibility requirements of the target application environment. Ensure the 1210 package dimensions align with the printed circuit board land pattern specifications.

Common Mode Chokes Selection Notes

Select this component when a low-profile, unshielded common mode choke is required for 1210 footprints. The 90 Ohm impedance at 100 MHz targets specific frequency ranges for noise reduction. Evaluate the 300 mA current limit to ensure it accommodates the maximum operating current of the protected circuit without saturation or excessive heating.

Common Mode Chokes Part Context

This part belongs to the RGCMF series of common mode chokes from Walsin Technology Corporation. The series offers various impedance values and current ratings within standard surface-mount packages. The RGCMF1210900H3T specifically addresses applications requiring moderate impedance and current handling in a small form factor.

Common Mode Chokes Replacement Considerations

Check for alternative parts with identical 1210 dimensions, 90 Ohm impedance at 100 MHz, and similar current ratings. Verify pinout compatibility and thermal characteristics if substituting with components from other manufacturers.
