Product Information

Matsushita/Panasonic 50F Supercapacitor -20 → +80% Tolerance, HW 2.3V dc, Through Hole

Gold Capacitors are Electric Double Layer Capacitors.

They were developed by the Central Research Laboratory of MATSUSHITA ELECTRIC INDUSTRIAL COMPANY in 1972, then marketed and sold on a worldwide basis in 1978. Because these capacitors function as a battery, they are ideally suited for applications requiring a secondary power source such as a back-up energy source for microprocessors and solar battery.
Generally, capacitors have dielectric between two opposite electrodes. For example, Aluminum Electrolytic
Capacitors use an aluminum oxide film, and Tantalum Capacitors use a tantalum oxide film as dielectric.
However, the electric double layer capacitor does not have dielectric but uses a physical mechanism that
generates an electric double layer which performs the function of dielectric, hence, the name Electric Double
Layer Capacitor. The charge-discharge factor in the element of electric double layer capacitors is an ion
absorption layer which is formed on the surface of the positive and negative electrodes of activated carbon,
to utilize absorption-desorption reactions.

HW Series

Panasonic HW electric double layer capacitors (gold capacitors) offer a low resistance, high capacitance, miniaturised solution. In comparison to secondary batteries, these supercapacitors have many more charge and discharge cycles.

Organic electrolyte and activated carbon ensures that these capacitors are pollution free
Does not contain lead or polyvinyl chloride
Wound type

Applications

Suitable applications include quick charging motor circuits, back up power supplies (UPS) and solar battery operated circuits.

Specifications

PLEASE NOTE!

These parts came to us as part of a lot of surplus stock from a large distribution Co. and have been kept in storage for a time, we have therefore classified them as new other, they are however unused and in good serviceable condition – the photographs are of one of our actual stock, and, as with all our products they come with a full guarantee.
