Inductors: Development and mass production of high reliability, automotive power inductors

Shunluo Inductance Power Inductor SWPA Series First Class Agent

TDK Corporation (President: Sakamoto Kenhiro) developed the CLF6045NI- D series of power inductors for automotive power circuits, and will begin mass production in February 2015.

In recent years, with the development of electronic electronics, electronic control units (ECUs) are increasing, and power inductors are used in these power supply circuits. We have developed the CLF6045NI- D series of high-efficiency, high-reliability power inductors that can meet the wide temperature range of -55°C to +150°C, which can meet the harsh environment of the engine compartment with the most severe conditions.

This series of products is in line with AEC-Q200. In addition, with the unique material technology of the company, high-heat-resistant materials are selected, and the welding method is introduced in the broken part to realize a welded-free structure. In addition, with its unique structural design, it has improved mechanical strength and can be applied to ECUs such as engine control modules (ECM), airbags, ABS, and headlights. And by introducing the manufacturing process of the automated streamlined generation line, high-reliability, high-quality product supply is realized.

The product size is 6mm square (L: 6.3 × W: 6.0 × H: 4.5mm), and a small size of 5mm square, 7mm square, 10mm square, 12.5mm square medium and large size products will be added in the future. A wide range of products are available for design use.

main application

Various vehicle-mounted electronic control units (ECUs) such as engine control modules (ECM), airbags, ABS, and headlights

Main features and advantages

Develops a wide temperature range from -55 ° C to +150 ° C by developing materials with excellent heat resistance

High reliability through unique structural design that increases mechanical strength

Main characteristics

Rated current 1: based on the rate of change of the inductor (less than 30% of the nominal value)

Rated current 2: Based on temperature rise (temperature rises 40 ° C)
