What is a tantalum polymer capacitor?

A tantalum polymer capacitor is a different kind of capacitor that uses a conductive polymer and a tantalum oxide as the anode.

What are the main features of tantalum polymer capacitors?

Cost: More expensive than other capacitors.

It works better than traditional tantalum capacitors.

Mild failure modes make applications easier.

Lower ESR than traditional tantalum capacitors.

Higher breakdown voltage.

Lower DC leakage current than conventional tantalum capacitors, even under extreme radiation conditions.

What are the uses for tantalum polymer capacitors?

Automotive: sensors, door control, tire pressure, climate control.

Industrial: power supplies, door locks, fire detectors.

Measurement: positioning systems, flow meters, gas monitors.

Lighting: headlights, traffic lights, displays, signs.

Medical engineering: hearing aids, pacemakers, handheld devices.
