Kirchzarten, Germany - Hi-Rel COTS T83 series solid tantalum chip capacitors from Vishay Intertechnology and distributed by Ecomal are designed to provide high reliability and a choice of standard and low-ESR values in five different case sizes. Designed for a variety of avionics and military systems such as radar, missiles, and other weapons systems, the T83 capacitors offer capacitance/voltage values not available in current military specifications, allowing designers to reduce the size, weight, and component count of existing assemblies. The molded case capacitors are available in five case codes, sizes A through E, per EIA-535BAAC. They provide designers with a high-reliability, screened capacitor that does not require a source control or customer drawing. The devices, part of the TANTAMOUNT tantalum capacitor family, have a capacitance range of 0.1 µF to 330 µF and voltage range from 4 V to 35 V. This capacitance/voltage range represents 40 % more values than existing equivalent military offerings. Devices in the T83 series operate over a temperature range of -55 °C to +125 °C.
Part number coding allows designers to select termination plating, reliability screening, surge current test conditions, and ESR level. The option of low ESR values, which extend down to 0.1 Ohm at +25 °C and 100 kHz, allows for more efficient filtering in critical dc-to-dc conversion applications, while the T83’s high ripple current handling capability is key for ensuring stable output voltages. Their extended capacitance/voltage values, coupled with reliability, surge current, and ESR options, make the T83 tantalum capacitors a flexible solution for a wide variety of applications and performance levels.
