Company card

Founded in 1969 in Taiwan; FIRSTOHM is one of the few companies who are able to design resistors according to customer's requirements. The experience gained from more than 40 years of develop and manufacture of resistors it’s the best foundation for bring any customer request and find a solution. So FIRSTOHM can propose not only a excellent choice of “trought hole” and “melf” resistor but can also co-operate by following way:

  • Resistor application consulting
  • Development of specialty resistor according to your requirements
  • Resistor COST DOWN by equivalent substitute and multi-functional resistor to reduce other components.

With the constant research of best quality, during the years FIRSTOHM achieve this follow certification:

  • 1998 Awarded DIN EN ISO-9002 by TUV CERT Certification Body of TUV Anlagentechnik GmbH, Germany
  • 2000 ISO 14001 certified
  • 2001 ISO 14001 Green Dove Award received
  • 2004 High-Voltage Resistor (HVR series) passed VDE0860 (EN60065)
  • 2011 ISO 9001:2008 certified- SGS patent granted by European Patent Office
  • 2012 SGS patent granted in Japan, China, and Korea
