Company profile

Changzhou Jiaqi Electronics Co., Ltd. has been a professional diode manufacturer since 1997. Except for several offices in different cities, we also have two factories. One is in Cailing Industrial Park, Changzhou, Jiangsu Province and the other in Suining Industrial Park of Sichuan Province. Now the total number of employees reaches 1000, technicians account for 11% among them. Jiaqi company has now got ISO9001-2008 certificate, RoHS and REACH certificates.

The main products include Solar Diodes (10SQ045, 12SQ045, 15SQ045...), surface mount diodes (M7,RS1M,US1M,ES1J...) and axial series, such as 1N4007 (10kk/ 20 day delivery time). For development and market demanding, the company increases advanced production lines and professional testing equipments, based on the original equipments. Our product quality and lead time has been greatly improved by means of the new equipments and testers.

Due to our principle of customer-oriented, timely adjustment of product structure, we successfully win the good comments from new and old customers basing on "standard quality, competitive price and great service." Diodes of JQC brand are very famous in domestic electronic area, we will promote the overseas market more and better.The aim for us is to make our own brand name JQC to be internationally acknowledge.
