MLCCs Suit High Temperature Apps

24 January 2017

CGA series MLCCs. Source: TDK CGA series MLCCs. Source: TDK TDK Corporation has expanded its CGA series of automotive-grade MLCCs for high-temperature applications: New MLCCs with X8L temperature characteristics have been introduced and the capacitance range of its existing X8R types has been extended. With the new types, TDK's lineup of X8L and X8R MLCCs features a high capacitance range of up to 22 µF. These capacitors offer high reliability at temperatures from -55 °C to +150 °C, with a capacitance drift of just ±15 percent for the X8R types and +15/-40 percent for the X8L types.

The high-temperature MLCCs were made possible by the development of a new dielectric material that maintains high reliability even in extreme environments. To further improve reliability, the X8R dielectric material is now also available for soft-termination and conductive epoxy MLCCs, which help to prevent board flexure cracks and solder cracks caused by thermal stress. The AEC-Q200 qualified MLCCs are suited for applications in high temperature environments such as engine compartments or in close proximity to transmission oil tanks.
