World's Highest Capacitance! Murata Launches Mass-production of GCJ Series Monolithic Ceramic Capacitors with Resin External Electrode for Automotive Applications Up to 150°C

Overview

Murata Manufacturing Co., Ltd. has launched mass production of "monolithic ceramic capacitor with a resin external electrode for automotive applications" that has X8L characteristics*1 and is designed for use in applications up to 150°C. The GCJ series capacitor is available in a 3225 package and has a capacitance value of 10µF (rated voltage 25V) . This new product is the world's first capacitor with a resin external electrode that features X8L characteristics. This 3225-size GCJ series capacitor provides the world's highest capacitance value.

Background

In recent years, the automobile market has placed a great deal of importance on improving efficiency and environmental resistance performance. To perform higher-precision control, cases of assembling electronic components closer to the engine and transmission are increasing. Therefore, there is strong demand for capacitors that can be used in a high-temperature environment of 150°C. To meet this demand, Murata has developed a product that achieves X8L characteristics by optimizing the resin external electrode.

Furthermore, there are cases where capacitors are mounted on a lead frame*2 in order to achieve size and weight reduction of the devices. As a result, there is the need for capacitors with a fail-safe function to prevent short-circuit even when bending stress is applied to these devices. The resin absorbs mechanical stress when a circuit board is bent and the mechanical strength can be improved by using resin for the electrodes.

Features

  • X8L characteristics achieved by product with resin external electrode.
  • Capacitance value of 10µF with a rated voltage of 25V achieved in a 3225-size product.

Applications

Automotive devices such as engine control units (ECU) , transmission control units and sensors that must withstand high temperatures and require a fail-safe function.

Part number

GCJ32EL81E106K

External Size

L: 3.2±0.4mm; W: 2.5±0.3mm; T: 2.5±0.3mm

Production

Mass production starts at Izumo Murata Manufacturing Co., Ltd. from October 2012.

Terminology

*1 X8L characteristics: Characteristics that provide a capacitance variation of +15/-40% in the range between -55°C and 150°C.
*2 Lead frame: Used in a semiconductor package such as an IC. This is a component that secures the semiconductor chip and connects the chip to external wiring.
