0603USB-142MLC

Overview

The Coilcraft 0603USB-142MLC is a surface-mount common mode choke designed for high-speed signal lines. It features an inductance of 98 nH and a maximum DC resistance of 0.174 ohms. The component supports a maximum DC current of 500 mA and operates within a temperature range of -40°C to +85°C. Its impedance is specified at 420 ohms, with physical dimensions of 1.52 mm in length.

Feature Summary

• Engineered specifically for filtering noise on high-speed signal transmission lines
• Provides compact surface-mount integration suitable for space-constrained PCB layouts

Applications

• High-speed data interface protection
• Signal integrity enhancement in digital circuits
• Noise suppression for USB or similar high-frequency data buses

Procurement Notes

Verify the specific suffix (MLC) against the manufacturer's official datasheet to confirm tolerance and packaging specifications. Ensure compatibility with the target PCB footprint and reflow soldering profile. Confirm availability status through authorized distributors as supply levels may vary by region.

Selection Notes

Select this component when a low-inductance common mode filter is required for high-speed signals. Compare the 98 nH value against signal rise times to ensure adequate attenuation without excessive phase distortion. Verify that the 500 mA current rating exceeds the operational peak current of the protected line.

Part Context

This part belongs to the 0603USB series from Coilcraft, which focuses on small-footprint filtering solutions. The series targets applications requiring minimal board space while maintaining effective noise suppression for modern high-speed digital interfaces.

Replacement Considerations

Consult the official Coilcraft datasheet for direct pin-compatible alternatives within the same series. Verify that any substitute maintains the 98 nH inductance and 0.174 ohm DCR specifications.
