EXC-18CE650U

Common Mode Chokes Overview

The Panasonic EXC-18CE650U is a common mode noise filter array designed for high-speed differential transmission lines. It operates within a temperature range of -40°C to +85°C and features a compact 0603 case size measuring 1.6 mm in length, 0.8 mm in width, and 0.4 mm in height. The component provides a common mode impedance of 65 Ω with a tolerance of ±20%. It supports a maximum DC current of 140 mA and maintains a maximum DC resistance of 1.8 Ω under a rated DC voltage of 5 V. The device contains two built-in filter circuits and utilizes a multilayer sintered construction.

Common Mode Chokes Feature Summary

• Low DC resistance and low insertion loss characteristics suitable for signal integrity
• RoHS compliant construction that is lead, halogen, and antimony-free

Common Mode Chokes Applications

• Noise suppression of high-speed differential data lines
• Information equipment applications
• AV equipment noise filtering

Common Mode Chokes Procurement Notes

Verify the specific suffix 'U' indicates embossed carrier taping with a 4 mm pitch during procurement. Confirm the manufacturer designation as Panasonic Electronic Components or Panasonic Industry to ensure authenticity. Check RoHS compliance status against current regulatory requirements. Validate the impedance value of 65 Ohms matches the design specifications. Ensure the package dimensions align with the 0603 footprint requirements.

Common Mode Chokes Selection Notes

Select this component when low DC resistance is critical for maintaining signal quality in high-speed interfaces. The 65 Ohm impedance level is appropriate for specific frequency ranges requiring moderate common mode attenuation. Consider the 140 mA current rating to ensure it meets the operational load without saturation. The small form factor allows for dense PCB layouts where space is constrained.

Common Mode Chokes Part Context

This part belongs to the EXC series of common mode filters from Panasonic, specifically engineered for Mbps and Gbps transmission speeds. The series includes variants like EXC18CE900U and EXC18CE201U with different impedance values. These components are designed to suppress noise while minimizing waveform rounding effects on transmitted signals.
