Vishay BCcomponents Film Dielectric Trimmers TEST VOLTAGE (DC) FOR 1 MINUTE: FEATURES 500 V * High temperature type MAXIMUM CONTACT RESISTANCE: * Housing dimensions: 8 mm x 9 mm x 10 mm 5 m * For a basic grid of 2.54 mm Pb-free MINIMUM INSULATION RESISTANCE: e3 RoHS COMPLIANT * Versions available with 1 or 2 rotor contacts * Top and bottom adjustment 10 000 M * Vertical version CATEGORY TEMPERATURE RANGE: APPLICATIONS - 40 to + 125 C * For fine adjustment professional applications DESCRIPTION: CLIMATIC CATEGORY (IEC 60068): 40/125/21 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. MINIMUM STORAGE TEMPERATURE: 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. - 55 C Flux absorption between the vanes is prevented. Cleaning with solvents is not advised.
