We started the development of capacitors with large capacitance and for high ripple current, ahead of other companies. Now, our capacitors for mid- to high-voltage have a high market share. Our Screw Terminal Type Aluminum Electrolytic Capacitors are used for inverters for trains and elevators etc. in the fields that are required to offer high reliability.

Features
•Through the self-development of high-quality anode foil and electrolyte, high reliability and excellent cost performance have been achieved.
•Our products are used for the equipment that requires a large capacitance such as inverter and large power source.
•Lead-free/Conforming to RoHS Directive

Advantages and disadvantages

Terminations to screw terminals can be made with simple hand tools and do not require a mating connector to be applied to the wire end. The connections are physically and electrically secure because they firmly contact a large section of wire. The connectors are relatively low cost compared with other types of connector and a screw terminal can easily be integrated into the design of a building wiring device (socket, switch, or lamp holder).

Disadvantages include the time taken to strip a wire and properly wrap it around the screw head. This is slower than a plug-in connector, making screw connections uncommon for portable equipment. If the wire is too small, it can be cut through by an overtightened screw head. Wire strands may not be contained by the screw head, so sometimes stranded wires are crimped into a ferrule to prevent bridging of terminals; this partly offsets the economy of a "bare" wire termination. Wires must never be tinned prior to installation in a screw terminal, since solder will cold flow resulting in a loose connection and serious fire hazard.

Screw connectors sometimes come loose over time if not done up tightly enough at fitting time. Verifying adequate tightening torque requires calibrated installation tools and proper training. In the UK all screw connectors on fixed mains installations are required to be accessible for servicing for this reason.
