Vehicle navigation is a subject that integrates automobile, computer, communication, transportation, system science and other fields of technology, and has been the focus of many high-tech companies and universities at home and abroad.

Automotive inductors The requirements for inductors are small and high performance. Although the specifications of inductors required for each application are different, one common denominator required for the use of inductors in vehicle equipment is "high reliability". Compared with the inductors used in general living equipment such as mobile phones and computers, the inductors used in vehicle equipment work in a relatively harsh environment, and the requirements for the reliability of components are also very strict.

In order to meet the high reliability requirements, the company for the automotive navigation equipment installed in the inductor, in the use of materials and product structure in the design of repeated tests and reliability verification, for the vehicle components, must be in the minimum use temperature and the maximum use temperature between 1000 cycles of thermal shock test. Among them, the general specification of the (inductor) for on-board equipment is -40℃+105℃, and 1000 cycles of thermal shock tests must be carried out at this temperature condition.
