Overview

Murata Manufacturing Co., Ltd. today announced the development and launch of its GRT series of automotive-grade monolithic ceramic capacitors. These capacitors meet the AEC-Q200 reliability test standard requirements established by the Automotive Electronics Council.

Background

Murata’s capacitors have been traditionally used in applications in three main fields: general applications, automotive powertrain safety applications, and implanted medical devices. Due to increasing demand the GRT series have been developed for use in the automotive infotainment and comfort-and-convenience industries.
Recent years have witnessed an ever-rising demand for automotive-grade monolithic ceramic capacitors that meet the requirements of the AEC-Q200 automotive electronic component standard, inspiring Murata to develop and commercialize the GRT series. The series consists of capacitors with 299 part numbers for temperature-compensating, and 519 part numbers with a high dielectric constant, for a total of 818 part numbers. These components are designed to enhance reliability and reduce physical sizes for infotainment and comfort-and-convenience applications that are required to meet the AEC-Q200 standard.
