BFC2 809 080.. Vishay BCcomponents Film Dielectric Trimmers TEST VOLTAGE (DC) FOR 1 MINUTE: FEATURES • High temperature type 500V • Housing dimensions: e3 10mmx11mmx11mm MAXIMUM CONTACT RESISTANCE: • For a basic grid of 2.54mm 5 mΩ • Vertical version with a round head • Top and bottom adjustment MINIMUM INSULATION RESISTANCE: APPLICATIONS 10 000 MΩ • For fine adjustment in professional applications DESCRIPTION: CATEGORY TEMPERATURE RANGE: The trimmers consist of a polysulphone housing, brass rotor - 40 to + 125 °C and plated brass stator with PTFE film as the dielectric. The stator plate tags are heat sealed to the housing. The rotor contact surfaces are plated to ensure a long life CLIMATIC CATEGORY (IEC 60068): 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. Cleaning with solvents is not advised. MINIMUM STORAGE TEMPERATURE: - 55 °C QUALITY LEVEL: Sampling and data evaluation for quality level in accordance with “MIL-STD-105D” and “IEC60410”: RELATED SPECIFICATION: < 0.15 % major defects IEC 60418-1 and 4 < 0.65 % minor defects Each capacitor is tested for minimum C and is also max subjected to the full test voltage. EFFECTIVE ANGLE OF ROTATION: C /C : min max 180° (rotation in 180° only, see “Life of Trimmer”) 4/38 to 5/57 pF OPERATING TORQUE: RATED VOLTAGE (DC): 2 to 25 mNm 250V LIFE OF TRIMMER: MAXIMUM AXIAL THRUST: Maximum 10 cycles: rotation in 180° only (the electrical and mechanical performance is not guaranteed if rotated beyond 2 N 10 cycles) Document Number 28531 For technical questions, contact: dc-film@vishay.com www.vishay.com Revision: 18-Oct-07 333
