DBF50166BQ125P36CB

Overview

The DBF50166BQ125P36CB is a high-voltage film capacitor manufactured by Vishay Beyschlag/Draloric/BC Components. It features a capacitance of 125 pF with a tolerance of ±10%. The component is rated for a DC voltage of 25,000V (25kV). This specific part number is currently listed as obsolete.

Feature Summary

• Capable of handling extreme electrical potentials up to 25kV
• Provides precise low-value capacitance for specialized circuitry

Applications

• High-voltage pulse generation circuits
• X-ray and medical imaging equipment power supplies
• Industrial electrostatic precipitators

Procurement Notes

This component is officially marked as obsolete by the manufacturer. Sourcing requires verification of remaining stock from authorized distributors or secondary market suppliers. Designers should initiate immediate replacement strategies to ensure long-term supply chain stability.

Selection Notes

Selection requires matching the 25kV DC rating and 125pF value strictly. Verify physical dimensions and terminal configuration against the original design constraints. Consider thermal derating requirements if operating near maximum voltage limits in enclosed environments.

Part Context

This part belongs to Vishay's high-voltage film capacitor portfolio, designed for demanding industrial and medical applications. It utilizes metallized film technology to achieve high insulation resistance and reliability under significant electrical stress conditions.

Replacement Considerations

Direct substitutes include other 125pF ±10% capacitors rated for at least 25kV DC. Ensure the alternative component meets the same physical footprint and mounting style requirements to fit existing PCB layouts without modification.
