SAFETY

Designed to protect today’s equipment and systems,

Littelfuse semiconductor fuses are manufactured with

Littelfuse-developed technology that sets tomorrow’s stan-

dards for accuracy, consistent quality, reliability, and predict-

able performance. By using advanced metallurgical, polymer,

and materials research; mathematical modeling, and comput-

erized statistical analysis; Littelfuse engineers have redefined

“State-of-the-Art.”

ꢀ

200,000 A.I.R. — Reliable interruption of all overcurrents up

to 200,000 amperes . . . meets present and future system

requirements. (Note: L15S series has 100,000 A.I.R.)

Extremely Current Limiting — Low I²t and peak let-through

ꢀ

currents meet most semiconductor requirements.

ꢀ

UL Recognized — Littelfuse semiconductor fuses are

recognized under the components program of Underwriters

Laboratories, Inc., and carry the

semiconductor fuses may be used to provide supplemen-

tary protection in UL listed equipment.

mark. UL Recognized

APPLICATIONS

Designed specifically for supplementary protection of

semiconducting devices such as silicon controlled rectifiers

(SCR’s), diodes, thyristors, triacs, transistors, and similar

solid-state devices. These devices are used in power

equipment including variable speed drives, power rectifiers,

UPS systems, DC power supplies, and in a wide range of

electronic equipment.

LONGER EQUIPMENT LIFE

ꢀ

Low Watt Losses — Means less heating and power

consumption in circuit.

ꢀ

Controlled Transient Overvoltages — All circuits are subject

to transient overvoltages during fault current interruption.

These transient overvoltages (arc voltages) start when fuse

links melt or circuit breaker contacts part, and subside

when circuit is interrupted. Semiconductors are very

sensitive to overvoltages. Littelfuse semiconductor fuse

designs keep transient overvoltages to low levels and help

reduce semiconductor failure.

May be used wherever extremely fast-acting, current-limiting

fuses with no time delay are required.
