MCF12102G900-T

Common Mode Chokes Overview

The MCF12102G900-T is a multilayer common mode choke coil manufactured by Taiyo Yuden, designed for signal line filtering applications. It features a 1210 (0504 metric) surface-mount package with four terminals. The component exhibits an impedance of 90 Ohms at a test frequency of 100 MHz and supports a maximum DC current of 100 mA. Its maximum DC resistance is 4.5 Ohms, with a rated DC voltage of 5V. The device operates within a temperature range of -40°C to +85°C and includes internal shielding to minimize electromagnetic interference.

Common Mode Chokes Feature Summary

• Multilayer construction provides compact footprint for high-density PCB layouts
• Integrated magnetic shielding reduces external electromagnetic interference
• Optimized for high-frequency noise suppression in signal integrity circuits

Common Mode Chokes Applications

• USB 2.0 interface data line protection
• High-speed digital signal filtering
• Noise suppression in portable electronic devices

Common Mode Chokes Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Confirm RoHS3 compliance and moisture sensitivity level (MSL 1) requirements during storage and handling. Review the latest product change notification (PCN) for any manufacturing updates. Ensure compatibility with existing PCB footprints and soldering profiles before integration into production lines.

Common Mode Chokes Selection Notes

Select this component when a shielded, low-profile common mode choke is required for 5V signal lines carrying up to 100 mA. The 90 Ohm impedance at 100 MHz makes it suitable for suppressing common mode noise without significantly attenuating differential signals. Consider the 1210 package size constraints and thermal operating limits of -40°C to +85°C during design validation.

Common Mode Chokes Part Context
