KOA’s UR73-series thick film shunts are designed for current detection, especially in demanding environments. The special facedown construction makes lower resistance values with a low T.C.R. possible.
Compared to KOA’s existing UR73-series the new UR73V-series has an even better T.C.R. and its wide operating temperature range of -55°C to +155°C makes it ideal for applications such as automotive or hi-rel DC-DC converters.
The T.C.R. of ±100 ppm/K is specified for resistance values higher than 11 mO.
The UR73V-series covers the resistance range from 10 mO to 100 mO and is available in 1206 size (inch).
Resistors in the range 30 mO to 100 mO are designed for standard mounting whilst values in the range 10 mO to 27 mO use a facedown construction.
Not only is the total T.C.R. minimized due to the cancellation of the top electrode and the solder fillet T.C.R., but also lower resistance values are achieved with the facedown construction.
Features:
- Low resistance (100mO or under) and high accuracy
(±1%) for current detection - High reliability and performance with T.C.R. of ±100ppm/K
- Suitable for flow and reflow solderings
