Vishay Intertechnology, Inc. announced that it has expanded the capacitance range of its M39006/33 (Style CLR93) tantalum-cased, hermetically sealed wet tantalum capacitor. Offering established reliability for critical avionics and aerospace systems, the device is reportedly the industry’s first capacitor qualified to the MIL-PRF-39006/33 specification to offer capacitance from 15 to 680 microfarad over a wide voltage range from 50 to 100 volts.

The extended Vishay Sprague capacitor combines high capacitance and established reliability with good reverse voltage, vibration and thermal shock performance. Optimized for timing, filtering, energy hold-up and pulse power applications in power supplies for space and avionics equipment, the device allows designers to incorporate fewer capacitors into these products to lower overall system costs.

Offered in the axial T1, T2, T3, and T4 case sizes, the M39006/33 features capacitance tolerance of ± 10 and ± 20 percent standard and maximum ripple current of 2750 milliamps. The device operates over a temperature range of negative 55 degrees Celsius to positive 85 degrees Celsius, or to positive 125 degrees Celsius with voltage derating.

Samples and production quantities of the extended M39006/33 capacitor are available now, with lead times of 10 weeks for large orders.
