2499-003-X5U0-501M

Overview

The 2499-003-X5U0-501M is a tubular EMI feedthrough filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. This axial lead component features a capacitance of 500 pF with a tolerance of ±20%. It is rated for a maximum voltage of 500 V and can handle a continuous current of 20 A. The device utilizes an X5U dielectric material, providing stable performance across its operating temperature range. Designed for panel mounting via a bushing configuration, it serves as a high-frequency noise suppression element in electronic circuits.

Feature Summary

• Provides effective electromagnetic interference (EMI) attenuation through feedthrough capacitor technology
• Supports high continuous current loads up to 20 A for robust power line filtering
• Features axial leads and a bushing mount style for secure panel integration

Applications

• Power supply input filtering in industrial equipment
• EMI suppression in aerospace and defense avionics systems
• Noise reduction in medical instrumentation power lines

Procurement Notes

Verify the specific suffix codes against official Tusonix or CTS documentation to ensure correct dielectric type and termination style. Confirm that the 20 A current rating aligns with your circuit requirements. Check for RoHS compliance status if required by your manufacturing standards. Ensure panel cutout dimensions match the physical bushing specifications provided in the datasheet.

Selection Notes

Select this component when high-current handling capability is required alongside significant capacitance for low-frequency noise suppression. The 500 V rating makes it suitable for higher voltage DC or AC applications. Consider the axial bushing form factor for direct panel penetration mounting solutions where space constraints favor vertical installation over surface mount alternatives.

Part Context

This part belongs to the Tusonix 2499 series of tubular feedthrough capacitors. These components are engineered for harsh environments, offering superior reliability compared to standard discrete capacitors. The series is widely recognized in sectors requiring stringent EMI/RFI mitigation, such as military, aerospace, and critical infrastructure electronics, due to their hermetic sealing capabilities and stable electrical characteristics.

Replacement Considerations

Direct substitutes may include other 500 pF, 500 V feedthrough capacitors from manufacturers like Vishay or Johanson Technology. Verify that any replacement matches the 20 A current rating and axial bushing mechanical dimensions. Cross-reference the X5U dielectric properties to ensure equivalent temperature stability.
