BFC2 809 080.. Vishay BCcomponents Film Dielectric Trimmers TEST VOLTAGE (DC) FOR 1 MINUTE: FEATURES High temperature type 500 V Housing dimensions: e3 10 mm x 11 mm x 11 mm MAXIMUM CONTACT RESISTANCE: For a basic grid of 2.54 mm 5 m Vertical version with a round head Top and bottom adjustment MINIMUM INSULATION RESISTANCE: APPLICATIONS 10 000 M For fine adjustment in professional applications DESCRIPTION: CATEGORY TEMPERATURE RANGE: The trimmers consist of a polysulphone housing, brass rotor and plated brass stator with PTFE film as the dielectric. The - 40 to + 125 C 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: QUALITY LEVEL: - 55 C Sampling and data evaluation for quality level in accordance with MIL-STD-105D and IEC 60410: RELATED SPECIFICATION: < 0.15 % major defects < 0.65 % minor defects IEC 60418-1 and 4 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): 250 V 2 to 25 mNm 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 333BFC2 809 080..
