What is it?

New product to be released to achieve <1mΩ steps within the entire output range. Samples are available in two weeks.

Spec. of model QR102A-K5-R0:

Output Range	Steps	Accuracy(Referred to Setpoint)	TC	Rated power
1.5Ω to 500Ω	<1mΩ	±0.015%±3mΩ@Tcal±5℃	less than ±(10ppm+0.5mΩ)/℃	>1W

Can be in serial with QR101 (or other fixed-value resistor) to make the whole range (or desired range) capable with 1mΩ step.

What makes it special?

Unlike QR100/101 that the accuracy is based on "reading" or "process value" (for example when you need a 100.0 Ohm while the device can only output 99.95 Ohm - although it will tell you it's 99.95 Ohm), QR102 makes it possible to output the exactly the resistance value "100.000" you want.
