Susumu was established in 1964 as a thin film resistor specialist. Since then they have been introducing innovative thin film resistors and serving virtually all segments of the electronics industry where precision and high quality resistors are required. When the RG series was introduced in 2003, it had (and still has) the best absolute tolerance and temperature coefficient of resistance among thin film chip resistors. The URG series which is Susumu’s latest innovation, is the reliability enhanced version of the RG series whose reliability is already top notch.
