AVX launches high capacitance 150degC MLCCs
AVX Corporation has announced its new X8L dielectric multilayer ceramic capacitors that deliver high capacitance values at temperatures of up to 150degC. The new parts extend AVX’s high temperature MLCC range: previously-available X8R dielectric parts are also rated for use at similarly high temperatures and are very stable with temperature, but do not offer the same high capacitance performance at elevated temperatures.
X8R and X8L MLCCs are RoHS-compliant and feature excellent low loss performance and good temperature stability - X8R devices exhibit a capacitance variation over temperature of ±15% between -55ºC and +150ºC, while X8L products have a variation of ±15% between -55 to 125degC and +15/-40% from +125 to +150degC. Absolute capacitance will vary with temperature, but as an example, at ambient (25degC) temperature the new X8L parts deliver a CV of 0.47µF/25V in an 0805 package, whereas the comparable X8R device is rated at 0.22µF/25V. X8L parts also extend the voltage available from 50V (X8R) to 100V.
Optional termination systems include AVX’s patented FLEXITERM® which resists damage caused by thermal cycling and mechanical flexing, ensuring the parts are very reliable. Conductive epoxy terminations for hybrid applications are also available.
Comments Slavomir Pala, product marketing manager at AVX: “Like the X8R parts, the new, high capacitance X8L MLCCs are AEC-Q200-qualified which suits them to automotive applications such as under the bonnet systems. In the industrial market, they can also be used as bulk capacitors for temperature sensing modules as well as control units.
