The Surge Protection is Not An Option. It's A Necessity!

We at JumboTek Technologies, Inc. pride ourselves on being one of the few companies whose products offering are exclusive to varistors and thermistors. Since 1980, Mr. C. B. Chiang, the founder of JumboTek, has developed and specialized in solving the most difficult electrical transient problems for business, industry, and government sectors. The increased complexity, miniaturization of products spurs the need for a greater number of passive components and protective devices that are simultaneously smaller, yet more complex. The JumboTek rises to the challenges.
