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
