The physical length of the unit is 17.5 mm, providing a compact form factor suitable for panel mounting applications.

Feature Summary

• Provides effective electromagnetic interference filtering through feedthrough architecture
• Utilizes X7R ceramic dielectric for stable performance across temperature variations
• Supports high voltage operation up to 500 Vdc in axial configuration

Applications

• Electromagnetic interference suppression in electronic enclosures
• Panel mount filtering for signal and power lines
• High-frequency noise reduction in sensitive instrumentation

Procurement Notes

Verify the specific capacitance tolerance requirements, as this part offers a wide range from 0% to +100%. Confirm that the 500 Vdc rating aligns with your circuit's peak voltage stresses. Ensure the axial lead style and 17.5 mm length fit within your mechanical constraints. Check RoHS compliance status directly with the manufacturer or distributor, as documentation may vary by production batch.

Selection Notes

Select this component when a feedthrough topology is required for superior high-frequency attenuation compared to standard capacitors. The X7R dielectric ensures reliability under varying thermal conditions. Consider the wide capacitance tolerance if precise tuning is not critical. Verify that the axial package allows for proper grounding through the chassis or panel structure.

Part Context

This component belongs to the Tusonix series of EMI feedthrough filters, manufactured by CTS Electronic Components. These devices are engineered to suppress radio frequency interference by providing a low-impedance path to ground for unwanted signals while allowing desired currents to pass through the center conductor.

Replacement Considerations

Consult official substitution guides for equivalent feedthrough capacitors with matching capacitance and voltage ratings. Ensure any replacement maintains the axial lead configuration and similar physical dimensions for direct board or panel integration.
