Leader Electronics LEI company introduction

Leader Electronics Inc.

Leader Electronics was founded in 1970 and began life as a manufacturer of audio transformers and film capacitors. LEI is located in Taipei, Taiwan and is one of the leading manufactures of switching power supplies and transformer products. Recently, LEI has developed products in the EV(electric vehicle) charging systems, energy storage system and brushless DC motor in order to be a one-stop shop energy solution provider.

Staying agile and driving the company to a new future

LEI strives to create a win-win-win relationship with its suppliers and customers. By working this way, customers benefit with higher quality and lower cost while suppliers get higher volumes and opportunities. Using these strategies has enabled LEI to become one of the world leaders in linear power adapters.

LEI also realized that investment in manufacturing development was a key to becoming a top tier company.​ We were on the forefront of new manufacturing technologies such as high-speed winding machines and automatic impregnation lines, which were very impressive in the mid 90’s on a global level. With our customer support, LEI expanded into downstream integration and turned into a professional ODM (original design manufacturer) in the switching power supply industry. Our clients are all over the world with the product application in networking power, industrial automation, industrial power, consumer electronics, or AIOT (Artificial intelligence of things). The company was publicly listed on TWSE in 2002. (stock code:3058)
