Vishay / Spectrol 43 Series 3/4" Multi-Turn Cermet Trimmer Resistors

Vishay / Spectrol 43 Series 3/4" Multi-Turn Cermet Trimmer Resistors offer a 0.75W power rating at a +70°C temperature rating and a wide resistance range of 10Ω to 5MΩ. These resistors are available with panel-mount versions and feature a multi-finger wiper for enhanced contact resistance variation (CRV). The 43 series resistors are tested according to CECC 41000 or IEC 60393-1 standards and offer 1000V dielectric strength, 400V limiting element voltage, and 3.5Ncm operating torque. Vishay / Spectrol 43 Series 3/4" Multi-Turn Cermet Trimmer Resistors are fully sealed with an IP67 protection rating and operate in the -55°C to +125°C temperature range.
