BFC2 808 ..... Vishay BCcomponents 10 mm Film Dielectric Trimmers TEST VOLTAGE (DC) FOR 1 MINUTE: FEATURES 300 V Housing diameter 10 mm Pb-free For a basic grid of 2.54 mm (0.1 ) or 2.50 mm e3 MAXIMUM CONTACT RESISTANCE: Top and bottom or top adjustment Vertical and horizontal versions 10 m RoHS COMPLIANT Round head MINIMUM INSULATION RESISTANCE: APPLICATIONS 10 000 M For consumer and industrial equipment CATEGORY TEMPERATURE RANGE: DESCRIPTION: PP The vanes of the trimmer are stacked on a sturdy plastic base. The color of the base indicates the maximum - 40 to + 70 C capacitance (see Electrical Data Table). The dielectric is a film of polypropylene (PP), polycarbonate (PC) or PC, PTFE polytetrafluorethylene (PTFE), which supports the vanes in - 40 to + 85 C such a way that good stability is ensured and no microphony can occur. CLIMATIC CATEGORY (IEC 60068): Flux absorption between the vanes is prevented. PP Cleaning with solvents is not advised. 40/070/21 Versions are available with either a vertical spindle, or a horizontal spindle. PC, PTFE Both versions have top adjustment by means of a screwdriver or trimming key and bottom adjustment by 40/085/21 means of a key. MINIMUM STORAGE TEMPERATURE: QUALITY LEVEL: - 55 C Sampling and data evaluation for quality level in accordance with MIL-STD-105D and IEC 60410: < 0.15 % major defects RELATED SPECIFICATION: < 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 : 180 (rotation in 180 only, see Life of Trimmer) min max 2.5/15 to 7/105 pF OPERATING TORQUE: RATED VOLTAGE (DC): 2 to 25 mNm 150 V MAXIMUM AXIAL THRUST: LIFE OF TRIMMER: 2 N Maximum 10 cycles: rotation in 180 only (the electrical and mechanical performance is not guaranteed if rotated beyond 10 cycles) www.vishay.com For technical questions, contact: dc-film vishay.com Document Number 28528 320 Revision 11-Oct-07BFC2 808 ..... 10 mm Film Dielectric Trimmers Vishay BCcomponents ROUND HEAD ROUND HEAD 2.5 2.5 0.6 0.6 0.7 0.7 11 11 max. max.
