With the PSR100 series, ROHM now has a much more compact version of its PSR series. These ultra-low ohmic shunt resistors have high power capabilities and are suitable for current measurement in industrial and automotive applications.
New resistors based on high-performance metal alloys as resistance elements have an excellent temperature coefficient (TCR) from ± 50ppm to ± 150ppm. Thanks to the company's innovative precision welding technology, they can produce a high power rating of 3W and an ultra-compact form factor of 6.35mm x 3.05mm. Their resistance ranges from 0.3mOhm to 3.0mOhm. The resistance tolerance is specified as F (± 1%). Operating temperature range is –55C to + 170C.
This series is the ideal solution for automotive and industrial applications and many other areas where performance and size are critical. For example, in addition to UPS and base stations, these include electronic compressors in cars, car chargers, and EPS.
