2499-540-X7W0-502ZLF

Overview

The 2499-540-X7W0-502ZLF is an axial feed-through capacitor manufactured by Tusonix, a subsidiary of CTS Electronic Components. This component functions as an electromagnetic interference (EMI) filter designed for high-voltage applications. It features a capacitance value of 5000 pF with a tolerance range of -20% to +80%. The device is rated for 500 Vdc at 85°C and supports a current capacity of 10 A. The physical length of the unit is 17.5 mm. It utilizes an axial leaded configuration suitable for panel mounting or bushing installations.

Feature Summary

• Provides effective electromagnetic interference suppression through feed-through capacitor architecture
• Supports high voltage operation up to 500 Vdc with robust current handling capabilities
• Features axial leads for secure mechanical integration into equipment panels

Applications

• High-voltage power supply filtering
• Industrial control system EMI suppression
• Medical equipment noise reduction
• Aerospace electronic systems filtering

Procurement Notes

Verify the specific capacitance tolerance requirements against your design specifications, as this component offers a wide variance from -20% to +80%. Confirm that the axial lead configuration and 17.5 mm length are compatible with your panel cutout dimensions. Ensure the operating environment temperature does not exceed the rated limits for the X7W dielectric material. Cross-reference the manufacturer part number to ensure authenticity from Tusonix or CTS.

Selection Notes

Select this component when high-voltage isolation and significant current carrying capacity are required alongside EMI filtering. The X7W dielectric provides stable performance across varying temperatures. Consider the physical size constraints due to the 17.5 mm length. Evaluate if the wide capacitance tolerance meets the precision needs of your circuit. Compare against other feed-through capacitors if tighter tolerances or different mounting styles are necessary.

Part Context

This part belongs to the Tusonix family of EMI feed-through filters, which are specialized components designed to attenuate radio frequency interference in electrical circuits. These filters typically integrate capacitive elements within a conductive housing, allowing signals to pass while shunting noise to ground. The product line is widely used in industries requiring reliable noise suppression in high-power environments.

Replacement Considerations

Direct substitutes must match the 5000 pF capacitance, 500 Vdc rating, and axial form factor. Verify that alternative parts support similar current ratings and have compatible physical dimensions for existing panel mounts. Check for equivalent dielectric materials to ensure similar thermal stability.
