T493 series

The T493 series is designed for the COTS (Commercial-Off-The-Shelf) requirements of military/aerospace applications. This 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 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.
