Company Profile
Jingdacheng Electronics(JDC) is a leading power resistors
manufacturer in China, and we are always focusing on providing
various resistors and loading solutions since it was established in
1997. With 24 years industry experiences, JDC has a professional
team for resistor designing, manufacturing and quality control, and
most of our managements have been working for JDC at least 10
years. Even approved by ISO9001:2014, JDC started proceeding a very
high standard (Japan JIS) of manufacturing and quality inspection
since we built a long partner cooperation with Japan IWAKI MUSEN in
2013. Now, JDC is providing many resistors and solutions for some
top500 companies, Such as: Huawei, Yaskawa, Panasonic, Midea, etc.
Our main products: Power resistors, Aluminum housed resistors, Wirewound resistors,
Blower motor resistors, DC Shunt, Water cooled resistors, Carbon
composition resistors, Ceramic composition resistors, Load bank,
Crowbar resistors, Neutral grounding resistors, Ceramic housed
resistor, Braking resistors.
