Vishay Intertechnology Releases Its New MKT1826 Capacitor

Vishay Intertechnology Inc. (Malvern, PA) announced the release of a stacked, metallized, polyester-film capacitor that they claim provides improved pulse handling and self-healing capabilities, as compared with devices built on conventional wound-film technology. The new Vishay Roederstein MKT1826 features a compact design and, the company maintains, superior reliability. It is intended for coupling, blocking, bypassing, filtering, timing, arc suppression and energy storage, and is suitable for general use in telecommunications, automotive, consumer and industrial products.

The new MKT1826 varies in package size, according to the capacitance and voltage rating, from 2.5 x 7.2 x 6.5mm to 7.2 x 7.22 x 13.0mm. The lead spacing on all parts is 5.0mm, and the casing on the packages is flame-retardant, with lead-free schooping layers.

The MKT1826 features a capacitance range of 23 options spanning from 1,000pF to 4.7µF. Capacitance tolerance options of ±5 percent, ±10 percent and ±20 percent are available. Voltage options of 40Vdc, 40Vdc, 63Vdc, 100Vdc and 250Vdc are also provided. The MKT1826 is suitable for high-temperature applications, with an operating temperature range of -55 degrees to 125 degrees C in the 4.7µF, 40Vdc version. The maximum pulse rise time ranges from 120V/µs to 350V/µs, depending on the voltage rating.

“The MKT1826 offers excellent electrical parameters, a compact size and an environmentally friendly construction," stated Heinz Dornecker, product manager at Vishay.

Samples and production quantities of the MK1826 are available now, with 8- to 10-week lead times for larger orders.
