TDK broadens range of automotive ceramic capacitors

March 15, 2016 // By Christoph Hammerschmidt
With the new CGA6 and CGA 9 series of high-voltage Multi-layer ceramic chip capacitors (MLCCs), passive components manufacturer TDK claims to offer the broadest capacity for such capacitors for automotive applications. The CGA6 and CGA9 series of MLCCs, which have a rated voltage of 1000 V, feature types with capacitances ranging from 1 nF to 33 nF.

The MLCCs are available with both C0G and NP0 temperature characteristics. They thus feature a temperature coefficient of 0 ±30 ppm/°C max. and temperature ranges of 55 °C to +125 °C and -55 °C to +150 °C, respectively. As a result, capacitance drift over temperature is negligible. The capacitors also exhibit nearly no drift over voltage and time, making them suitable for applications where high capacitance stability of the components is essential. The CGA6 and CGA9 MLCCs measure in with footprints of 3.2 mm x 2.5 mm (EIA 1210) and 5.7 mm x 5.0 mm (EIA 2220), respectively. Mass production began in March 2016.


Not only do the new MLCCs deliver a constant capacitance under all conditions, their AC energy losses and heat generation are also very low. They are suited for use in the wireless charging units, DC-DC converters and on-board chargers in electric and plug-in hybrid vehicles, and wherever space savings and high performance are required.


Because the new products are qualified according to AEC-Q200, they are suitable for use in the engine compartments of automobiles and other automotive applications. Moreover, the MLCCs can be used in various other types of circuits in industrial equipment where high reliability is essential, for example in timer circuits, filter circuits, resonance and oscillation circuits, and snubber circuits.
