Exxelia Ohmcraft HVCD 3512

The Ohmcraft HVCD Series 3512 chip divider is a high-precision, high-voltage surface-mount component designed for demanding applications requiring stable and accurate voltage division. Utilising Ohmcraft’s proprietary Micropen® precision printing technology, the HVCD 3512 achieves superior performance with resistance values ranging from 40 MΩ to 10 GΩ. With a voltage rating of up to 2,000V and ratio tolerances as tight as ±1%, this chip divider ensures accurate and consistent operation in high-voltage circuits. The low TCR tracking of ±25 ppm/°C enhances temperature stability, while its ultra-low noise characteristics make it ideal for precision measurement and control applications. The compact 3512 package allows for efficient PCB layout in space-constrained designs.
