EXC-18CE201U

Common Mode Chokes Overview

The Panasonic EXC-18CE201U is a common mode noise filter array designed for high-speed differential transmission lines. It operates within an impedance range of 65 to 900 Ohms with a ±20% tolerance. The device supports rated DC currents from 100 mA to 140 mA and maintains a maximum DC resistance between 1.8 Ω and 3.5 Ω. Rated for 5 V DC, it features a compact 0603 (1.6 mm × 0.8 mm) footprint with a height of 0.4 mm. The component functions across a temperature range of -40°C to +85°C and utilizes a multilayer sintered construction for reflow soldering reliability.

Common Mode Chokes Procurement Notes

Verify the specific impedance value required for your application, as the EXC-18CE series includes variants such as 90, 200, and 650 Ohms. Confirm that the 0603 package dimensions and 5 V rating align with your circuit design constraints. Ensure compatibility with RoHS compliance standards if applicable to your manufacturing region. Check official datasheets for precise thermal characteristics and current ratings before finalizing procurement decisions.

Common Mode Chokes Selection Notes

Select this component when space-constrained designs require effective common mode noise filtering for Mbps or Gbps interfaces. The choice depends on matching the specific impedance requirement to the target frequency band while ensuring the DC resistance remains low enough to prevent excessive voltage drop. Consider the operating temperature range and mechanical robustness provided by the sintered structure for reliable surface mount assembly.
