Automotive-grade approvals for multilayer ceramic chip capacitors

October 15, 2013 // By Christoph Hammerschmidt
TDK's CGA3EA series of automotive grade MLCCs meet the ESD immunity requirements according to the IEC 61000-4-2 standard. The components are available in package size 1608 (EIA 0603) and offer rated capacitances ranging from 1 nF to 10 nF and a rated voltage of 100V.

The new series comprises two types of MLCCs with different thermal characteristics: C0G components with a temperature range of -55°C to +125°C and a temperature coefficient of 0 ±30 ppm/°C max., and NP0 components with a temperature range of -55°C to +150°C and the same temperature coefficient.

The material used in the CGA3EA series features a low dielectric constant and thus maintains stable performance even when load conditions such as temperature or voltage change. The new components are therefore able to withstand ESD events of up to 8 kV and higher, as proven by the contact discharge test according to IEC 61000-4-2 (level 4). Mass production of the CGA3EA series, which is qualified to AEC-Q200, started in October 2013.

The CGA3EA series are able to offer reliable ESD protection in a wide range of automotive electronics applications such as airbag controllers, remote keyless entry systems, navigation systems and more.
