RIK

bulk metal resistor

– industrial grade

The RIK resistor is the industrial version of the world patented RCK02

resistor retaining the stability, high frequency response, rapid rise times

and low noise of the RCK02 series at highly economical pricing.

The RIK resistors have been designed to enable compact side by side

mounting on a 2,54 mm PCB pitch and are designed for circuits that

require very fast rise times and high stability with temperature and

time such as in analog computing devices, process control, weighing

machines

● VERY HIGH STABILITY (<50 ppm/year (shelf life)

● TOLERANCE : ± 0,1% to ± 1%

● RISE TIMES : down to 1 nanosecond

● LOW TEMPERATURE COEFFICIENT <10 ppm/°C from –55°C to +125°C

< 5 ppm/°C from 0°C to +60°C

● CLIMATIC CATEGORY : –55°C/+125°C/56 days
