T493 series

The T493 series is designed for the COTS (Commercial-Off-The-Shelf) requirements of military/aerospace applications. T493 series series is a surface mount tantalum product offering various leadframe surface finishes, Weibull grading and surge current testing options. The full part number includes a code defining the terminations, the Weibull reliability,surge test conditions, and the ESR range. The possible terminations of T493 series include gold plated, hot solder dipped, solder plated, and solder fused. Reliability grading of B level (0.1%/kHours) and C level (0.01%/kHours) are available. Surge current testing options include: 10 cycles at 25ºC, or 10-cycles at -55ºC and +85ºC. Both standard and low ESR options are available. All lots of this series are conditioned with MIL-PRF-55365 Group A testing.

The electrical of the T493 series can be summarized as:(1)operating temperature range:55°C to +125°C;(2)non-operating temperature range:55°C to +125°C;(3)capacitance:0.1F to 1000F;(4)working DC voltage (WVDC):3 to 50 volts;(5)reverse voltage and polarity:+25°C--15% of rated voltage;+85°C--5% of rated voltage;+125°C--1% of rated voltage.And it can be used in handling,termination coating,recommended mounting pad geometries and soldering.
