About us​​

Jetronics Ltd. was established in 1976 as a company specializing in choke coils, line filters, adaptors, transformers and related electronic components. We are committed to providing high quality products and adhere to the tenet of "Customer First". We strive to be consistently superior to competitors in fulfilling customer's needs. Jetronics set up manufacturing facilities in China in 1991 and extended the plant area to a well-equipped 2nd production facility in 2002, manufacturing electronic components under the brand name ON-TECH and producing OEM products. While under expansion, in the early 1990s, we further expanded our manufacturing facilities to include plastic injection machines, bringing the entire manufacturing process under one roof.

Jetronics is a ISO/TS16949:2009 certified manufacturer. We have acquired the ISO 9001 and the ISO 14001 accreditation for many years. We have committed to maintain the environmental protection and have implemented green, lead-free production. The ISO/TS16949:2009, ISO 9001:2008 and 14001:2004 international standards are implemented to establish the integrated management system of quality and environment to assure our products leave our factory with best quality.
