[SatNews] Vishay Intertechnology, Inc. (NYSE: VSH) has extended its TANTAMOUNT® 597D series of commercial solid tantalum chip capacitors with a new Hi-Rel version approved to Defense Logistics Agency (DLA) Specification 13008. Built with Vishay's proprietary high-voltage dielectric formation process, the Vishay Sprague 13008 series is ideal for +28 V power supply designs in aerospace and military applications.

These new capacitors are optimized for DC/DC conversion and power distribution in space-based electronics, weapons and radar systems. To ensure performance in these safety-critical applications, the devices offer high-reliability screening and surge current testing options in accordance with MIL-PRF-55365.

Available in nine case sizes, 13008 series capacitors provide a wide array of ratings not previously found in available MIL specifications, including a capacitance range of 10 μF to 1500 μF over a voltage range from 4 V to 63 V. The devices' 63 V rating allows designers to meet derating requirements of 50 percent rated voltage for use in MIL-STD-1275 +28 V power supply designs. Their dual anode construction ensures the lowest ESR in their class, down to 0.015 Ω at +25 degrees C and 100 kHz.

The 13008 series operates over a temperature range of -55 degrees C to +85 degrees C, to +125 degrees C with voltage derating. With their conformal coating, the capacitors offer better volumetric efficiency than molded devices. This allows for higher capacitance-voltage (CV), a figure of merit that measures the amount of energy a capacitor can store.

Samples and production quantities of the new DLA 13008 capacitors are available now, with lead times of 12 to 14 weeks for larger orders.
