TDK Co., Ltd. (President: Sakamoto Kenhiro) has developed a FG series for halogen-free general use and a FA series laminated lead-through capacitor for automotive use, and will start mass production from April 2015.

We are promoting the development of products with low environmental impact and life cycle. This time, a product that does not use a halogen has been developed, and this halogen has been included as a flame retardant in a packaging resin portion of a laminated lead wire capacitor, thereby enriching the lineup of the product.

The normal FG series has a rated voltage range of 6.3V to 630V, an electrostatic capacity range of 1pF to 100μF, and a vehicle-mounted FA series with a rated voltage range of 25V to 630V and an electrostatic capacity range of 100pF to 22μF. In addition, the automotive FA series conforms to the AEC-Q200 standard, and the NP0 and X8R features greatly enrich the product lineup that ensures a high temperature of 150 °C.

In recent years, as the safety and comfort of automobiles have increased, the number of small motors mounted in each car has reached more than 100. In the noise countermeasures of these small motors, laminated conductors are widely used by welding, caulking, and the like. In the face of the growing demand for small motor noise countermeasures in the future, we will contribute to the expansion of our product lineup.

* Chlorine and bromine: 900 ppm or less each, totaling 1,500 ppm or less
