CA2C227M050B

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.

• All-Tantalum electrodes eliminate silver migration
• Withstands high ripple current
• Long life reliability
• Reverse voltage capability
• Instant use after long storage
