Series CS2 www.vishay.com Vishay Wet Tantalum Capacitor, Button, All-Tantalum Case, - 55 °C to + 125 °C Operation FEATURES • All-Tantalum electrodes eliminate silver migration • Withstands high ripple current • Long life reliability • Reverse voltage capability • Replacement for “A” series range of silver cased buttons • Mounting: Through-hole PERFORMANCE CHARACTERISTICS Operating Temperature: - 55 °C to + 125 °C Voltage Range: 3 VDC to 70 VDC Capacitance Range: 50 μF to 750 μF SPECIFICATIONS INTRODUCTION Environmental classification: 55/125/56 The design employs a non-solid electrolyte and a sintered tantalum anode. Vibration: 10 Hz to 2000 Hz, 0.75 mm or 98 m/s2, 15 h The cathode is also of tantalum and overcomes the restriction of the silver cathode system in allowing a high ripple current rating and application of a 3 V reverse potential. This all-tantalum construction results in a non-catastrophic wear-out mechanism. The seal is a high efficient system comprising a PTFE gasket clamped between coined plates of tantalum by a work-hardened nickel ring. This type of seal is common to all button styles it is largely responsible for their long life and high reliability and severe military environment. APPLICATIONS The CS2 series are designed as a direct replacement for the obsolete “A” series, where there is no standard CA unit at the required capacitance, and voltage, or when the standard CA unit (8.5 mm) is not acceptable. It should be noted that the upper category temperature of the CS2 unit is 125 °C for the “A” unit. Bump: 390 m/s2, 4000 bumps Shock: 981 m/s2 Acceleration: 981 m/s2 Low air pressure: 1 kPa REVERSE VOLTAGE CAPABILITY The CS2 series employs tantalum cathodes which allow the continuous application of reverse potentials not exceeding 3 V over the whole temperature range. SURGE VOLTAGE The surge voltage capability is 115 % of the voltage rating at the relevant temperature. TEMPERATURE RANGE The capacitor is designed for operation between - 55 °C and + 125 °C, with linear voltage derating above + 85 °C to 66 % of the rated voltage at + 125 °C. WEIGHT CAPACITANCE TOLERANCE The approximate weights (in grams) for the CS2 capacitors is 14.5 g. The standard capacitance tolerance is ± 20 % although special tolerances are available by arrangement.

All capacitors are subjected to burn-in. This is to remove infant mortalities and ensure reliability. The capacitor lifetime is enhanced when the unit is subjected to a reduced ripple current, a low ambient temperature, and is externally cooled. In timing circuits, or other applications where the device is subjected only to a DC voltage, the ballistic or DC capacitance will be somewhat larger than measured at 50 Hz. The parametric information must necessarily be brief, although additional comprehensive data is available on request, and the tests tailored to customers’ requirements can be made.
