Safety Precautions

Multilayer Varistors (hereafter refereed to as “Varistors”) should be used for general purpose applications as

countermeasures against ESD and noise found in consumer electronics (audio/visual, home, office, information &

communication) equipment. When subjected to severe electrical, environmental, and/or mechanical stress beyond the

specifications, as noted in the Ratings and Specified Conditions section, the Varistors may fail in a short circuit mode

or in an open-circuit mode. This case results in a burn-out, smoke or flaming.

For products which require high safety levels, please carefully consider how a single malfunction can affect your

product. In order to ensure the safety in the case of a single malfunction, please design products with fail-safe, such as

setting up protecting circuits, etc.

Strict Observance

1. Confirmation of Rated Performance

The Varistors shall be operated within the specified rating/performance.

Application exceeding the specifications may cause deteriorated performance and/or breakdown, resulting in

degradation and/or smoking or ignition of products. The following are strictly observed.

(1) The Varistors shall not be operated beyond the specified operating temperature range.

(2) The Varistors shall not be operated in excess of the specified maximum allowable voltage.

(3) The Varistors shall not be operated in the circuits to which surge current and ESD are applied exceeding the

specified maximum peak current and maximum ESD.

(4) Never use for AC power supply circuits.

2. The Varistors shall not be mounted near inflammables.

Operating Conditions and Circuit Design

1. Circuit Design

1.1 Operating Temperature and Storage Temperature

The specified “Operating Temperature Range” found

in the Specification is the absolute maximum and

minimum temperature rating. Every Varistor shall be

operated

within

the

specified

“Operating

Temperature Range”.

The Varistors mounted on PCB shall be stored

without operating within the specified “Storage

Temperature Range” in the Specifications.
