BFC2 809 080.. Vishay BCcomponents Film Dielectric Trimmers TEST VOLTAGE (DC) FOR 1 MINUTE: FEATURES 500 V * High temperature type * Housing dimensions: 10 mm x 11 mm x 11 mm MAXIMUM CONTACT RESISTANCE: 5 m e3 * For a basic grid of 2.54 mm * Vertical version with a round head * Top and bottom adjustment MINIMUM INSULATION RESISTANCE: 10 000 M APPLICATIONS * For fine adjustment in professional applications DESCRIPTION: CATEGORY TEMPERATURE RANGE: - 40 to + 125 C The trimmers consist of a polysulphone housing, brass rotor and plated brass stator with PTFE film as the dielectric. The stator plate tags are heat sealed to the housing. CLIMATIC CATEGORY (IEC 60068): The rotor contact surfaces are plated to ensure a long life and a stable contact even under severe climatic conditions. A colored dot indicates the maximum capacitance. 40/125/21 Flux absorption between the vanes is prevented. MINIMUM STORAGE TEMPERATURE: Cleaning with solvents is not advised. - 55 C QUALITY LEVEL: Sampling and data evaluation for quality level in accordance with "MIL-STD-105D" and "IEC 60410": RELATED SPECIFICATION: < 0.15 % major defects IEC 60418-1 and 4 < 0.65 % minor defects Each capacitor is tested for minimum Cmax and is also subjected to the full test voltage.
