Series CH2 Vishay Wet Tantalum Capacitor, Button, All-Tantalum Case, - 55 C to + 150 C Operation FEATURES * All-Tantalum electrodes eliminate silver migration * Withstands high ripple current * Long life reliability * Reverse voltage capability * Mounting: Through-hole PERFORMANCE CHARACTERISTICS Operating Temperature: - 55 C to + 150 C INTRODUCTION This conveniently-packaged polar button unit employs a non-solid electrolyte, and has a sintered tantalum anode. The anode is produced from a medium capacitance powder and the lower CV product allows a tighter specification of capacitance stability, dissipation factor and leakage current. 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. Voltage Range: 3 VDC to 75 VDC Capacitance Range: 33 F to 470 F SPECIFICATIONS Environmental classification: 55/150/56 Vibration: 10 Hz to 2000 Hz, 0.75 mm or 98 m/s2, 150 h Bump: 390 m/s2, 4000 bumps Shock: 981 m/s2 Both anode and cathode consists of sintered compacts of high purity tantalum powder. The dielectric layer of tantalum pentoxid electrolytically formed on each compact is completely stable. The system is enclosed between a tantalum plate and a tantalum cup, with an outer nickel case. Acceleration: 981 m/s2 The seal is a highly 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 under severe military environments. The CH2 series employ tantalum cathodes which allow the continuous application of reverse potentials not exceeding 3 V over the whole temperature range. The combination of the tantalum pentoxide dielectric stability and the extremely efficient seal has been shown to ensure that there is no significant difference in electrical parameters or instant use behaviour after 10 years storage or longer. A shelf life in excess of 20 years is confidently expected. The surge voltage capability is 115 % of the voltage rating at the relevant temperature. There are four types of terminations and mounting options are available. These include a treated stud or bolt, PCB pins, a tab for panels, and ribbons leads slotted through-holes. These are illustrated in the photograph, and dimensional table drawing. The capacitor is designed for operation between - 55 C and + 150 C, with linear voltage derating above + 85 C to 66 % of the rated voltage at + 150 C. Low air pressure: 1 kPa REVERSE VOLTAGE CAPABILITY SURGE VOLTAGE TEMPERATURE RANGE CAPACITANCE TOLERANCE The standard capacitance tolerance is 20 % although special tolerances are available by arrangement. APPLICATIONS The CH2 series is designed for use in general military and professional applications. For example: Power supply "smoothing", filter networks, switching, by-pass, timer functions, and where reverse potential occur. WEIGHT RIPPLE CURRENT CAPABILITY The maximum allowable ripple current is 750 mARMS. This value applies under normal cooling conditions and is 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. The CH2 style with a stud termination weighs approximately 18.1 g, including the nut. The CH2 styles, which has a printed circuit board mounting, weighs approximately 17.3 g.

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.
