EXC-18CG430U

Common Mode Chokes Overview

The EXC-18CG430U is a common mode noise filter array from Panasonic, designed for high-speed differential transmission lines. It features a compact 0603 (1.6 x 0.8 x 0.4 mm) package with two built-in filter circuits. Key electrical specifications include a common mode impedance of 43 Ω at 100 MHz with ±25% tolerance, a maximum DC resistance of 1.8 Ω, and a rated current of 100 mA. The device operates within a temperature range of -40°C to +85°C and supports a rated voltage of 5 V DC.

Common Mode Chokes Feature Summary

• High-Q value and high impedance in the GHz zone for effective noise suppression
• Low DC resistance and low insertion loss to minimize signal impact
• Strong multilayer sintered construction ensuring excellent heat resistance for reflow soldering

Common Mode Chokes Applications

• Noise suppression of high-speed differential data lines
• Information equipment signal integrity protection
• AV equipment EMI filtering

Common Mode Chokes Procurement Notes

Verify the exact suffix designation against the manufacturer's latest datasheet to confirm impedance tolerance and specific performance characteristics. Ensure compatibility with standard SMT reflow profiles due to the multilayer sintered construction. Confirm RoHS compliance status as per the specific production batch documentation provided by Panasonic Industry.

Common Mode Chokes Selection Notes

Select this component when space-constrained designs require effective common mode noise filtering for Mbps or Gbps data lines. The 0603 footprint suits dense PCB layouts. Consider the 100 mA rated current limit for power line applications. The high Q value makes it suitable for maintaining signal integrity in high-frequency environments where waveform rounding must be minimized.

Common Mode Chokes Part Context

This part belongs to the EXC series of common mode filters from Panasonic Electronic Components. The series includes variants like EXC18CE and EXC18CS, offering different impedance values and terminal configurations. The EXC-18CG430U specifically targets applications requiring high impedance in the GHz range while maintaining a small form factor for modern electronic devices.

Common Mode Chokes Replacement Considerations

Consult official Panasonic substitution guides for equivalent parts within the EXC series. Verify that any alternative maintains the 0603 footprint and similar impedance characteristics at 100 MHz.
