Electronic component maker KYOCERA AVX has introduced commercial-grade stacked capacitors for high-frequency applications in the industrial and downhole oil and gas industries.

The KGP stacked multilayer ceramic capacitors (MLCCs) deliver higher capacitance values in the same mounting area as traditional capacitors to support miniaturisation and are made without lead or cadmium to support sustainability and ease standards compliance.

They also exhibit low equivalent series resistance (ESR) and inductance (ESL) to reduce noise and optimise performance. Metal lead frames suppress thermal and mechanical stress to ensure stability and durability.

The MLCCs are available in five EIA case sizes (1210, 1812, 1825, 2220 and 2225) with two stack sizes, maximum thicknesses spanning 3.4 to 6.95mm, and J or L leads. They are also available with three dielectrics – C0G, X7R and X7T.

The series is rated for operating voltages from 50 to 1500V, capacitances from 10nF to 47µF ±10% or 20% tolerance, and operating temperatures from -55 to +125˚C.

Applications for the series extend throughout the industrial, alternative energy, and downhole oil and gas industries and include power supplies, DC-DC converters, control circuits, high-voltage coupling and DC blocking.

“The new KGP series stacked MLCCs further expand our proven portfolio of capacitors optimised for growing markets with challenging performance requirements, including the power supply and downhole drilling markets,” said Zack Kozawa, director of MLCC product marketing at KYOCERA AVX (www.kyocera-avx.com). “They also support the miniaturisation and sustainability megatrends affecting these and other market segments.”

MLCCs with C0G and X7R dielectrics are available in all five EIA case sizes with the full range of rated voltage values and capacitance values up to 220nF and 47µF, respectively. Those with X7T dielectrics are available in three EIA case sizes (1210, 1812 and 2220) with 250, 450 and 630V rated voltages, and capacitance values up to 4.7μF.

All parts are tested for visual characteristics, capacitance values, dissipation factor, temperature coefficient, insulation resistance, dielectric strength, temperature cycling, steady state and load humidity, high temperature load, termination strength, bending, vibration resistance, and soldering heat resistance to ensure peak performance in a wide range of high-frequency applications. They are also RoHS compliant and packaged on tape and reel in quantities of 500 to 1500 for automated placement.
