Series CA2 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 Instant use after long storage PERFORMANCE CHARACTERISTICS Operating Temperature: -55 °C to +125 °C Voltage Range: 6 VDC to 125 VDC Capacitance Range: 47 μF to 1800 μF SPECIFICATIONS Environmental classification: 55/125/56 Vibration: 10 Hz to 2000 Hz, 0.75 mm or 98 m/s2, 15 h Bump: 390 m/s2, 4000 bumps Shock: 981 m/s2 Acceleration: 981 m/s2 Low air pressure: 1 kPa INTRODUCTION This conveniently-packaged polar button unit employs a non-solid electrolyte, and has a sintered tantalum anode. The anode is produced from a high capacitance powder resulting in a capacitor of small size and large CV product. The cathode is also of tantalum and overcomes the restrictions of a 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, common to all button styles, is largely responsible for their long life and high reliability and severe military environments. The CA2 series ranges are available in several termination options. These include a mounting stud and pins for circuit mounting. APPLICATIONS The CA2 series are designed for use in general military and professional applications. For example: Power supply “smoothing” filter networks, switching, by-pass, timer functions and where reverse potentials occur. WEIGHT The CA2 style with a stud termination weighs approximately 18.1 g, including the nut. The CA2 styles, which has a printed circuit board mounting, weighs approximately 17.3 g. APPROVALS These capacitors are available released to: • BS CECC 30 202 002 RIPPLE CURRENT CAPABILITY The maximum allowable ripple current is 1 ARMS up to 85 °C and 750 mARMS to 125 °C. These values apply under normal cooling conditions and are irrespective of frequency or waveform. The algebraic sum of the AC peak and DC voltages must not exceed the forward or reverse voltage ratings at the relevant temperature. At certain frequency/temperature/DC voltage combinations higher levels of ripple current may be used. The applications department should be contacted before the above levels are exceeded. REVERSE VOLTAGE CAPABILITY The CA2 series employ 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. CAPACITANCE TOLERANCE 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. The use of a heat sink is recommended. 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.
