UCHI.25D SPECIFICATION
High energy varistors (MOVs) are designed for various applications. UCHI® offers the thinnest Type 1 (class I) varistors and high quality Type 2 (class II) varistors with the highest Imax capability, on the market.
The Epoxy coated type products are heavy-duty metal oxide varistors designed mainly for industrial applications and SPDs. They are larger diameter versions of the conventional metal oxide varistor disc components. They can have standard rigid terminals from UCHI® or can be custom designed to fulfill a customer's need to handle high current and energy, facilitating the mounting onto printed circuit boards. The Epoxy Coated Series offers excellent surge protection for use in industrial and consumer electrical equipment, power distribution, control equipment, security/fire alarm systems, railroad equipment, switchboards, computers, telecommunications, power supplies and motor controls.
