Stacked MLCCs support miniaturization
Kyocera AVX releases the KGP Series of commercial-grade stacked capacitors targeting high-frequency applications in the industrial and downhole oil and gas industries. The new stacked MLCCs deliver higher capacitance values in the same mounting area as traditional capacitors to support miniaturization.
These stacked capacitors are manufactured without lead or cadmium to support sustainability and ease standards compliance. They also provide low equivalent series resistance (ESR) and inductance (ESL), minimizing noise and optimizing performance, and feature metal lead frames that reliably suppress thermal and mechanical stress for greater stability and durability. Applications 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 KGP Series stacked MLCCs, in C0G, X7R, and X7T dielectrics, are available in five EIA case sizes (1210, 1812, 1825, 2220, and 2225) with two stack sizes (maximum thicknesses spanning 3.40 to 6.95 mm), and “J” or “L” leads. Key specs include operating voltages ranging from 50 V to 1,500 V, capacitance values ranging from 10 nF to 47 µF ±10% or 20% tolerance, and an operating temperature range from -55°C to 125°C.
The stacked 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 220 nF and 47µF, respectively. MLCCs with X7T dielectrics are available in three EIA case sizes (1210, 1812, and 2220) with three rated voltages (250 V, 450 V, and 630 V), and capacitance values up to 4.7 μF.
These ceramic capacitors are tested for a range of factors to ensure performance in challenging high-frequency applications. These include 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. They are RoHS compliant and packaged for automated placement on tape and reel in quantities of 500–1,500.
