4204-050LF

Overview

The 4204-050LF is a third-order LC Pi filter EMI feedthrough component manufactured by Tusonix, a subsidiary of CTS Electronic Components. It features a capacitance value of 5000 pF and supports a maximum DC current of 10 A with a voltage rating of 100 V. The device utilizes an axial bushing package for chassis mounting, with physical dimensions of 7.34 mm in diameter and 11.89 mm in length. It provides an attenuation value of 65 dB at 100 MHz and operates within a temperature range of -55°C to +125°C.

Feature Summary

• Third-order LC Pi low-pass filter topology for enhanced high-frequency noise suppression
• Axial bushing design enabling secure chassis mounting for structural stability
• Capacitive coupling configuration optimized for data line EMI filtering applications

Applications

• Mobile device data lines requiring EMI suppression
• Electronic systems prioritizing noise reduction over fast signal edge preservation
• Chassis-mounted power or signal entry points in industrial equipment

Procurement Notes

Verify the specific manufacturer designation as Tusonix, a subsidiary of CTS Electronic Components, to ensure authenticity. Confirm that the axial bushing package matches your chassis hole specifications. Check RoHS compliance status and REACH SVHC declarations against current regulatory requirements for your target market before finalizing procurement orders.

Selection Notes

Select this component when circuit design demands significant attenuation at 100 MHz without compromising mechanical mounting integrity. The 10 A current rating suits moderate power applications. Ensure the 100 V rating aligns with system voltage levels. Consider the trade-off between superior EMI performance and potential signal edge degradation inherent to high-capacitance pi filters.
