URG Series	URG Series - The URG series of thin-film chip resistors has the reliability-enhanced version of Susumu’s RG series resistors. In addition to providing absolute resistance tolerance of +/-0.01% and a temperature coefficient resistance of +/- 2 ppm, the URG series offers far better reliability than the RG series whose reliability is already significantly higher than other thin-film chip resistors. For example, the maximum drift by load life test and high-temperature exposure test (test method: MIL-PRF-55342/JIS C5201-1) is specified as +/- 0.02% (0.1% for RG series).  More...

More about Susumu

History

Susumu HeadquartersIn 1964, in the midst of Japan's rapid economic and industrial growth, two young physicist/engineers had an innovative idea to create resistors using thin films deposited using vacuum technology. They started a new technology company called Susumu, meaning “moving forward” in Japanese, in Kyoto Japan. Coincidentally, it was the year of the Tokyo Olympic Games when Japan proved to the rest of the world how mature her technology had become. Since then, Susumu has been continuously introducing innovative electronics components backed by its core technology, thin film deposition. By the year 2000, Susumu's world market share in thin film resistors exceeded 50% and Susumu is maintaining this position to this day. Currently, Susumu is a global company still headquartered in Kyoto but with a worldwide sales network with direct subsidiaries and distributors.

Technology

Susumu has been an expert in a variety of thin film deposition techniques such as sputtering, vacuum evaporation, chemical vapor deposition, ion plating, and electro plating. Susumu has also accumulated other core technologies that are combined with thin film technology to produce innovative high technology electronics components. These technologies include fine pitch photolithography, micro-laser machining, and high density packaging. For a relatively small company, research and development have been Susumu's primary focus from its inception because Susumu realized that this was the key for developing new technologically advanced products. As a result, Susumu has been first introducing many innovative products. For example, the RG series of chip resistors are best thin film resistors available on the market the performance and reliability point of view. The RL series current sensing resistors boast the world's smallest size for the power rating. Susumu will continue embracing innovation into the future.
  1. Advanced original film deposition
    Plasma assisted chemical vapor deposition ion plating, sputtering and vacuum evaporation.
  2. Fine pattern photolithograph
    Both on flat surface and round surface.
  3. Micro laser machining technology
    Pattern generation, trimming, and scribing.
  4. High-density packaging technology
    Applied for micro-size chip components, BGA and leaded terminations via connected multi-stuck structure.
Quality

As a Japanese company, Susumu's company philosophy is built around total quality control. Taking advantage of Japanese traditional culture which forbids outside shoes worn inside the house, the factory is free of foreign material even outside of the clean rooms, a key to the production of thin film. No one is permitted to enter the factory wearing the shoes they wear outdoors. Since the ISO standard system was introduced in Japan, Susumu has been one of early adaptors for these international quality standards. Susumu's certification includes ISO9000, ISO14000, and TS 16949. From the beginning, quality has been essential part of life at Susumu.
Susumu Quality
Environment

Japan is a small country but full of natural beauty. Susumu has been committed to protecting Japan's environment and, of course, the earth. By nature thin film components use a minimal amount of material and last a long time allowing for the conservation of natural resources. Most of Susumu's products are not only RoHS compliant but also halogen free keeping the environment free of hazardous materials. As stated in Susumu's environmental policy which is compliant with ISO14000, Susumu operates its facilities by utilizing green technologies as much as possible by focusing on daily improvements to achieve zero emission.
