VM-35 Non-Inductive
Thick Film 35W Resistors
The VM-35 is a 35W high power resistor in TO220 style molded package for through-hole applications. The Non-inductive design fits high frequency applications and high-speed pulse circuits. Heat is extracted through a insulated metal tab. Small size and thin profile fit for high-density compact installations.
Applications
Inverters RF
High Frequency SMPS
UPS
Soft Start power unit for machine, motor control, drive circuit, industrial & automobile, measurements.
