Utilizing proprietary Micropen thick‑movie know-how, these resistors obtain tolerances right down to ±0.01%. And there are TCR (Temperature Coefficient of Resistance) values of ±2 ppm/°C.
“This mixture ensures extraordinarily secure efficiency over temperature, time, and working situations,” states Rhopoint.
“Engineers profit from extremely‑low noise, glorious linearity, and excessive voltage dealing with functionality, making Exxelia Ohmcraft components perfect for measurement, instrumentation, aerospace, medical, and metrology functions the place each microvolt counts.”
HVCD 5020
For instance, there may be the Exxelia Ohmcraft HVCD 5020, which is aimed toward functions requiring secure and correct voltage division.
Because the product identify signifies, it options excessive voltage chip dividers (HVCD). And a compact case dimension of 5020 permits for extra environment friendly PCB format in space-constrained designs. Rhopoint additionally cites a voltage ranking as much as 4000V, an influence ranking of 100mW and a resistance vary from 1600MΩ to 10GΩ.
The ratio tolerances out there are ±1%, ±2%, ±5%, ±10%, and ±20%, states the corporate, and a TCR (Temperature Coefficient of Resistance) monitoring of ±25 ppm/°C. It has an absolute TCR of ±100 ppm/°C.
You may see the datasheet on-line.

The complete vary of Exxelia Ohmcraft precision resistors could be discovered on the Rhopoint web site. And samples can be found on request.
Notice, as a design‑led technical distributor, Rhopoint says it should assist UK engineers in specifying and designing‑within the resistors. In different phrases, serving to with half choice, optimisation of resistor networks, and format steering.
The corporate relies in East Grinstead, UK.
