Wet Tantalum Capacitor, Button Assembly or Array, All-Tantalum Case, - 55 C to 5 C Operation FEATURES All-Tantalum electrodes eliminate silver migration Withstands high ripple current Long life reliability Reverse voltage capability Stackable PERFORMANCE CHARACTERISTICS Operating Temperature: - 55 C to + 5 C Voltage Range: 6 V DC to 5 V DC Capacitance Range: 5 μf to 9 μf INTRODUCTION The module series of capacitors comprise five individual button units which are connected in parallel to give a very high capacitance. The epoxy resin encapsulation within an epoxy resin box, measuring approx. 5 mm x 5 mm x mm gives an extremely robust construction which lends itself to bank mounting. The MC module incorporated CA or CE style buttons. These button capacitor styles are of all-tantalum construction using a tantalum anode and tantalum cathode with a non-solid electrolyte. This well-proven construction with its highly efficient seal combined with the resin encapsulation gives an extremely robust module of long life and high reliability under military and avionic environments with the capability of withstanding V in reverse, and of handling high levels of ripple current. APPLICATIONS These units are designed for use in general military, space avionics and professional applications. For example: Power supply smoothing, filter network, timer functions. SPECIFICATIONS Environmental Classification: 55/5/56 Vibration: Hz to Hz,.75 mm or 99 m/s, h Bump: m/s, bumps Shock: - Acceleration: - Low Air Pressure: kpa REVERSE VOLTAGE CAPABILITY Module units are polar capacitors which allow the application of reverse potentials not exceeding V at temperatures up to 5 C. SURGE VOLTAGE The surge voltage capability is 5 % of the voltage rating at the relevant temperature. TEMPERATURE RANGE The capacitor is designed for operation between - 55 C and + 5 C, with linear voltage derating above + 85 C to 66 % of the rated voltage at + 5 C. CAPACITANCE TOLERANCE The standard capacitance tolerance is ± % although special tolerances are available by arrangement. WEIGHT The approximate weight of a module is g.

APPLICATION INFORMATION Capacitors may be operated at less than the rated voltage, resulting in significantly reduced leakage current values. 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 5 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. RELIABILITY 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. STACKING The units are suitable for stacking by use of through bolts. It is strongly recommended that a metal heat sink is used between each unit in order to eliminate the possibility of hot spots. ESTABLISHED FAILURE RATE The MT range incorporates 75D capacitors which are structurally similar to and subjected to the same processes as our 5D and MIL-PRF-96 range which is to an established failure rate of level R,. % per h at a 6 % confidence level. The CECC system of testing does not readily yield data to prove these levels, but in-house testing supports this figure. Although failure rates derived from life tests are a useful guide, in practice capacitors rarely see conditions of a steady DC voltage and temperature. The construction of the MT module gives an ability to handle the high ripple currents at high frequencies, reverse voltages up to V, and extremes of temperature likely to be encountered in modern circuitry. ALTERNATIVE CONSTRUCTION Alternative constructions based on the module range with differing terminal configurations and capacitor combinations including series connected units are available.
