More compact devices are achieved, the company says, without sacrificing performance; the material is space qualified to MIL-PRF-38534 Class K. This 50V rated dielectric complements the existing 25V rated material and can be specified across DLI’s range of standard Thin Film architectures - including Di-Caps, Border Caps, Bar Caps and Gap Caps. With the temperature stability of an X7R material and a dielectric constant of 25,000 UX is suitable for ultra-broadband decoupling, broadband DC blocking, amplifier stabilisation and energy storage applications.
Full specification is: Capacitance Range 51 pF to 10,000 pF; Temperature coefficient of capacitance ±15% @ -55°C to +125°C; Dissipation Factor < 2.5% @ 1 MHz; Insulation Resistance >103 MΩ @ +25°C and Dielectric Withstanding Voltage of 250% of rated voltage. Finished products can be epoxy and wire bond assembled.
