Automotive grade MLCCs with high operating temperatures

Murata has released its GCB series of monolithic ceramic capacitors (MLCC) that have been designed for automotive applications.

The use of electronic components in automobiles continues to rise, particularly inside engine compartments, powertrains and safety devices. These are typically exposed to demanding environments and must have high levels of reliability and be able to function at high temperatures.

The GCB series of MLCCs features a maximum operating temperature of 200°C and is claimed to be capable of being bonded and mounted using the conductive adhesives commonly used to meet the demands of automotive environments.

The GCB series features a capacitance range of 1000pF to 0.47µF in 0402 and 0603 size. They have operating temperature ranges of -55 to 150°C (X8R), -55 to 200°C (X9M), and have a working voltage of 10 to 100Vdc.

The capacitors feature electrodes made of nickel and palladium that produce a high bonding reliability with conductive adhesives even during use in high-temperature environments. Furthermore, the terminal electrodes of the capacitors are said to have superior corrosion resistance compared with our previous and existing products.
