Susumu, the largest thin-film resistor OEM in the world, has been the global leader for thin film components for 60 years, serving telecommunication & networking, computers & storage devices, power supply equipment, test & measuring equipment, medical equipment, as well as automotive and consumer electronics.
Susumu is headquartered in Japan and has sales offices in the United States, China, South Korea, Germany and Singapore.
Susumu RG and KRL Series
Susumu’s RG Series, the most popular metal thin film chip resistors because of their high precision, high reliability and long-term
stability, is the base of Susumu’s line-up of new innovative products: a higher precision, higher operating temperature, higher
power handling capability, higher anti-surge capability version of the RG series and so on.
All of these products employ the inorganic passivation technology that enables high precision and high reliability.
In addition, Susumu’s thin film based terminal technology does not involve any Ag (silver) and they are sulfur impervious.
Features:
- Long term stability with inorganic passivation
- Less than ±0.1% drift after 10000 hours of reliability test
- High precision resistance tolerance: ±0.05%, very small TCR: ±5 ppm/℃
- Thin film structure enabling low noise and anti-sulfur
Susumu’s KRL Series metal foil low resistance chip resistor is the most precise current sensing resistor on the market. It has smaller package sizes with more power than any of its competitors.
Susumu’s products are all RoHS compliant and the company is accredited for ISO9001, 14001 and TS16949.
