Automotive-grade MLCCs offer operating temperature of 200C

Specifically designed for automotive applications, Murata has introduced the GCB series of monolithic ceramic capacitors (MLCCs). 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 not only high levels of reliability but be able to function at high temperatures too. To meet this requirement Murata has developed the GCB series of MLCCs with a maximum operating temperature of 200C. In addition they are capable of being bonded and mounted using the conductive adhesives commonly used to meet the demands of an automotive environment. The GCB series features a capacitance range of 1,000pF to 0.47uF in 0402 and 0603 size. They have operating temperature ranges of -55C to +150C (X8R), -55C to +200C (X9M), and have a working voltage of 10 to 100VDC. The capacitors feature newly developed electrodes made of nickel (Ni) and palladium (Pd). They produce a high bonding reliability with conductive adhesives even during use in high-temperature environments. Furthermore, the terminal electrodes of the capacitors have a superior corrosion resistance compared with previous and existing products. The GCB series satisfies the AEC-Q200 stress test qualifications for passive components, says the company.
