X8L capacitors

AVX Corp. adds AEC-Q200-qualified multi-layer ceramic capacitor (MLCC) that provide high capacitance values at temperatures of up to 150°C. Named the X8L series, the high-temperature MLCC range has an elevated capacitance performance at a temperatures range to accommodate applications in harsh environments including automotives.

"Like the X8R series, the new, high-capacitance X8L MLCCs are AEC-Q200-qualified making them ideal for automotive applications including 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," said Tim Piver, product marketing manager at AVX.

AVX's X8R and X8L series MLCCs are RoHS-compliant and feature excellent low-loss performance and temperature stability. X8R capacitors demonstrate a capacitance variation over temperature of ±15 per cent between -55°C and +150°C, while X8L products have a variation of ±15 per cent between -55°C to 125°C and +15/-40 per cent from +125°C to +150°C. Absolute capacitance will vary with temperature, but as an example, at ambient (25°C).

The new X8L capacitors deliver a CV of 0.47µF/25V in 0805 package, a comparable X8R device is rated at 0.22µF/25V. The X8L series also extends the voltage availability from 50V (X8R) to 100V.

Optional termination systems include AVX's patented FLEXITERM, which ensures the reliability of the components by preventing damage caused by thermal cycling and mechanical flexing reliable. Conductive epoxy terminations for hybrid applications are also available.

Pricing set at competitive market levels with lead time of 14 weeks.
