Multilayer ceramic chip capacitors drive automotive apps

Originally available only in 3225 to 5750 packages (EIA 1210 to 2220), the CKG series of MEGACAP Type MLCCs from TDK now include miniature 1608 to 3216 (EIA 0603 to 1206) packages. With dimensions of only 1.9 x 1.3 x 1.5 mm the new 1608 components are presented as the world's smallest automotive-grade MLCCs in the mega cap class. The new MLCCs in the smaller case sizes have a capacitance of 10 μF and rated voltages from 16 V to 25 V. The high-reliability, automotive-grade MLCCs with lead frames offer superior thermal shock and mechanical stress resistance. These components are designed for applications in automobiles, base stations and wherever highest reliability is essential. Mass production is scheduled to start in July 2013. The number of electronic control units (ECU) deployed in and near the engine compartment where extreme temperature conditions exist has increased significantly. The capacitors used in such harsh environments need to be extremely heat resistant and reliable. Along with high resistance to extreme temperatures, vibrations, and shock, the advanced structural design of the CKG series of MEGACAP Type MLCCs enables a very wide operating temperature range of -55 to +150 °C and optimal reliability for use in ECUs.
