4311-009

Overview

The Tusonix 4311-009 is a discoidal EMI feedthrough filter designed for high-frequency noise suppression. It features a capacitance of 500 pF and a rated voltage of 200 V, operating within a temperature range of -55°C to +125°C. The component utilizes an X7R dielectric material and employs a GMV tolerance standard. Physically, it measures 0.156 inches in diameter and 0.110 inches in height, with a length of 0.625 inches. This axial leaded device is intended for chassis or panel mounting applications requiring robust electromagnetic interference mitigation.

Feature Summary

• Provides effective attenuation of electromagnetic interference signals through feedthrough capacitor technology
• Utilizes X7R dielectric material for stable performance across specified temperature ranges
• Features a compact discoidal form factor suitable for space-constrained installations

Applications

• Electromagnetic interference filtering in electronic systems

Procurement Notes

Verify the specific suffix requirements when ordering, as non-LF versions may exist without explicit RoHS compliance documentation in general listings. Confirm that the selected variant matches the required thermal and electrical ratings for the target application environment. Ensure compatibility with the intended mounting method and lead configuration before finalizing procurement specifications.

Selection Notes

Select this component when a 500 pF capacitance value is required for high-frequency noise shunting at 200 V. Consider the physical dimensions and axial lead style for PCB or chassis integration. Evaluate the X7R temperature coefficient against the operational thermal profile to ensure consistent capacitance stability under varying environmental conditions.
