Vishay Intertechnology Extends 597D Series of Solid Tantalum Chip Capacitors with New DLA-Approved Devices
TANTAMOUNT® Capacitors Provide High Reliability for +28 V Power Supplies in Military and Aerospace Applications
MALVERN, Pa. — Vishay Intertechnology, Inc. (NYSE: VSH) today announced that it 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 military and aerospace applications.
The capacitors released today are optimized for DC/DC conversion and power distribution in weapons and radar systems, avionics, and space-based electronics. 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% 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 0.015Ω at +25°C and 100 kHz.
The 13008 series operates over a temperature range of -55°C to +85°C, to +125°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. Pricing for U.S. delivery starts at $4.00 per piece and varies by screening level and volume.
