BFC2 809 07... Vishay BCcomponents Film Dielectric Trimmers TEST VOLTAGE (DC) FOR 1 MINUTE: FEATURES • High temperature type 400 V • Housing dimensions: 11 mm x 14 mm x 9 mm MAXIMUM CONTACT RESISTANCE: • For a basic grid of 2.54 mm 5 mΩ • Top adjustment e3 • Vertical version MINIMUM INSULATION RESISTANCE BETWEEN APPLICATIONS STATOR AND ROTOR: • For fine adjustment in professional applications 10 000 MΩ DESCRIPTION: CATEGORY TEMPERATURE RANGE: The trimmers consist of a glass reinforced polysulphone frame with a polysulphone dust cover, brass rotor and stator with PTFE or polycarbonate film as the dielectric. The stator plates are stacked on pins and separated by rings, so that it is possible to produce a single stator or a differential type. - 40 to + 125 °C CLIMATIC CATEGORY (IEC 60068): The rotor contact surfaces are plated to ensure a long life and a stable contact even under severe climatic conditions. 40/125/21 QUALITY LEVEL: Sampling and data evaluation for quality level in accordance with “MIL-STD-105D” and “IEC 60410”: MINIMUM STORAGE TEMPERATURE: < 0.15 % major defects - 55 °C < 0.65 % minor defects Each capacitor is tested for minimum Cmax and is also subjected to the full test voltage.

Capacitance increase is obtained with clockwise rotation The trimmers are marked with the capacitance value in pF, followed by the letter ‘E’ (single-stator type) or the letter ‘D’ (differential type). MOUNTING: PACKAGING: The trimmer can be mounted on printed-circuit boards with a grid of 2.54 mm and a minimum hole diameter of 1.25 mm. Blister packs of 70 units each.
