Samsung Electro-Mechanics develops 2 MLCCs for autonomous driving vehicles

Samsung Electro-Mechanics, a subsidiary of Samsung components, said that they had launched two key multi-layer ceramic capacitors for autonomous driving systems.

One is smaller than any of the MLCC currently available for advanced driver assistance programs, or ADAS, measuring 0.6 millimeters in length and 0.3 mm across, as the company said. One has 47 microfarad storage.

The company expects the new products to be widely used in self-driving cars in the future. The smallest MLCC, called 0603 MLCC, is reduced by 64 percent by its previous size but retains the same final volume of 100 microfarads.

It will be used by the electronic control unit in private driving vehicles, which removes noise to deliver signals more accurately to drivers.

“Demand for smaller, larger storage and highly trusted MLCCs is rapidly growing as cars go electrified,” said Kim Doo-young, head of component business at Samsung Electro-Mechanics. “The company will continue developments and manufacturing of proprietary materials to expand its share in the automotive MLCC market.”

Samsung Electro-Mechanics doubled the size of the product compared to existing MLCCs to prevent partial injuries from external shocks and vibrations during driving. Product durability and quality are key factors in automotive MLCCs, added by Samsung Group.

The 47uF MLCC, which is 3.2 mm long and 1.6 mm wide, will take into account the stable power supply inside the vehicles. Samsung has doubled its storage volume in current products.

Increasing storage is important for MLCCs in private vehicles as ADAS is changing with the transfer and processing of large amounts of data. The firm said it was successful in further reducing the size of ceramic capacity, which is important for MLCCs, to protect storage.
