[INQ. NO. 2210E10] EL3 Inc. was founded in 2002 as a company specializing in manufacturing inductors and buzzers. For the past 20 years, it has supplied them to major electronic goods and home appliance manufacturers both at home and abroad.


Its main domestic customers include Novita, Inbody, Canon Korea, Doosan, and Mobase, and the number of overseas customers is increasing every year.

Inductors
An inductor is an electronic component made by wrapping copper or aluminum with insulating materials and then winding a coil around it.


When giving current to an inductor, it controls drastic changes in current by inducing the voltage in proportion to the current change.


EL3 is producing inductors at domestic plants, while some products are being supplied by a Chinabased OEM provider.


The company has obtained the certification “AEC-Q200” that requires high reliability and is providing its products for electronic goods and device-producing companies at home and abroad.

Buzzers
A buzzer is a tool that emits signal sound and is made of an electromagnet and a diaphragm. It is mainly used for electronic goods to make warning sounds, alarms, and others. Depending on the internal structure, it is divided into two: Magnetic and Piezo.


EL3 is being provided with both types by a Chinese OEM supplier. The company supplies its products mainly to small-sized electronic companies and security device manufacturers.

Ferrites
[INQ. NO. 2209E03] TODA ISU manufactures ferrite in the forms of ferrite powder and ferrite core, such as the super low power loss at high frequency (500kHz~1MHz) and the super low power loss at wide temperature ferrite for automobiles and the garnet ferrite of high dielectric constant used for telecommunication repeaters.

Inductors
TODA ISU manufactures and distributes the SMD inductors, including the high current, highefficiency inductor for 48V DC-DC converter for electric vehicles, and the high permeable inductor that reduced resistance and minimized heat emissions.

EMC filters
TODA ISU satisfies the demands of eco-friendly energy companies through supplying the EMC filter used as an electricity adjustment/conversion device in the areas of photovoltaic and renewable energy.

TODA ISU also manufactures power-supply devices in the range of 10W~1.6KW that are used for telecommunication and medical devices by using its own magnetic material and inductor.
