HFC-2L-3

Overview

The HFC-2L-3 is a radial feedthrough capacitor manufactured by TDK Corporation. It features a capacitance of 500 pF with a tolerance of ±35%. The component is rated for a maximum voltage of 10,000 V (10 kV). It operates within a temperature range of -30°C to +120°C and utilizes an E temperature coefficient. This device is designed for high-voltage filtering applications requiring robust performance in demanding environments.

Feature Summary

• Provides effective electromagnetic interference suppression through feedthrough architecture
• Engineered for high-voltage insulation capabilities up to 10 kV
• Constructed with radial leads for straightforward mounting configurations

Applications

• High-voltage power supply input filtering
• Industrial equipment noise suppression
• Medical imaging system signal conditioning

Procurement Notes

Verify the specific revision and manufacturing date code against current production status. Confirm that the radial lead configuration matches your PCB or panel layout requirements. Ensure the operating environment remains within the specified -30°C to +120°C range to maintain electrical integrity and longevity of the component.

Selection Notes

Select this component when high-voltage isolation and compact filtering are required. The 500 pF value suits high-frequency noise attenuation. Verify that the 10 kV rating exceeds the peak transient voltages present in the circuit. Consider the physical dimensions and lead spacing for mechanical integration into the assembly.

Part Context

This part belongs to TDK's feedthrough capacitor series, which are specialized components used for filtering signals in high-voltage environments. Feedthrough capacitors offer superior high-frequency performance compared to standard ceramic capacitors due to their low-inductance design. They are commonly utilized in aerospace, medical, and industrial sectors where reliability under extreme conditions is critical.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. When evaluating alternatives, ensure the replacement matches the 500 pF capacitance, 10 kV voltage rating, and radial package style. Verify that any substitute maintains equivalent thermal stability and impedance characteristics across the operating frequency spectrum.
