VISHAY BFC2 809 Series Trimmer Capacitor 5pF to 57pF

The VISHAY BFC2 809 Series Trimmer Capacitor is a high-performance, radial leaded component designed for precise adjustment in demanding electronic circuits. Featuring a unique top and bottom adjustment mechanism, it assists in energy conversion while delivering exceptionally low losses, high efficiency, and a long operational life.

Constructed with a robust polysulphone housing, the capacitor incorporates a brass rotor and a plated brass stator, using PTFE film as the dielectric. This plastic film construction effectively reduces microphony effects, making it ideally suited for sensitive impedance matching in RF circuits. The stator plate tags are heat-sealed to the housing for secure termination, and the plated rotor contact surfaces ensure a stable, reliable connection even under severe climatic conditions, guaranteeing longevity.

A convenient coloured dot indicates the maximum capacitance position for easy setup. The design prevents flux absorption between the vanes, maintaining consistent performance. This round-head, high-temperature type component is built for a standard 2.54mm basic grid, facilitating straightforward integration into PCB designs.

With an adjustable range from 5pF to 57pF and a rated DC voltage of 250V, this trimmer capacitor is a versatile solution for fine-tuning circuit parameters. Its through-hole mounting and screwdriver slot adjustment offer practical and reliable installation and calibration.
