Wet Tantalum Capacitor, Button,

All-Tantalum Case, - 55 °C to + 125 °C Operation

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.

FEATURES

• All-Tantalum electrodes eliminate silver migration

• Withstands high ripple current

• Long life reliability

• Reverse voltage capability

• Instant use after long storage

PERFORMANCE CHARACTERISTICS

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.

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 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.

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.
