4305-001

Overview

The Tusonix 4305-001 is an axial lead EMI feedthrough filter capacitor with a capacitance of 100 pF and a rated voltage of 200 V. It supports a maximum DC current of 5 A and operates within a temperature range of -55°C to +125°C. The component measures 3.55 mm in diameter and 10.16 mm in length, featuring 0.76 mm leads. Designed for solder mounting, it provides high-frequency noise suppression in compact electronic assemblies.

Feature Summary

• Provides effective electromagnetic interference attenuation through feedthrough capacitor architecture
• Supports high continuous direct current loads up to 5 amperes
• Maintains stable electrical performance across extreme industrial temperature environments

Applications

• High-frequency signal line filtering in communication equipment
• Power supply input/output noise suppression in industrial control systems
• EMI mitigation in aerospace and defense electronic assemblies

Procurement Notes

Verify the specific suffix designation when ordering, as the base model may have non-compliant variants while the LF version meets RoHS standards. Confirm physical dimensions and lead specifications against the target PCB layout requirements. Ensure the operating voltage and current ratings align with the circuit design parameters before finalizing procurement decisions.

Selection Notes

Select this component for applications requiring low-capacitance filtering where minimal signal distortion is critical. The axial package facilitates easy integration into existing through-hole designs. Consider the thermal rating when designing for enclosed spaces or high ambient temperature environments to ensure long-term reliability.

Part Context

This part belongs to the Tusonix 4305 series of discoidal EMI feedthrough filters manufactured by CTS Electronic Components. The series offers various capacitance values optimized for different frequency ranges. These components are widely used in military and aerospace sectors due to their robust construction and consistent performance under harsh conditions.

Replacement Considerations

Direct substitutes include other 100 pF axial feedthrough capacitors from manufacturers like Vishay or Johanson Technology. Verify that replacement parts match the 200 V rating, 5 A current capacity, and physical footprint dimensions to ensure compatibility without redesigning the mounting structure.
