REMENDED FUSE BLOCKS LSCR series:Refer to Fuse Block section of this catalog for additional information. Designed to protect today’s equipment and systems, Littelfuse semiconductor fuses are manufactured with Littelfuse-developed technology that sets tomorrow’s standards for accuracy, consistent quality, reliability, and predictable performance. By using advanced metallurgical, polymer, and materials research; mathematical modeling, and puterized statistical analysis; Littelfuse engineers have redefined “State-of-the-Art.” SAFETY s 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 ponents program of Underwriters Laboratories, Inc., and carry the mark. UL Recognized semiconductor fuses may be used to provide supplementary protection in UL listed equipment. s s APPLICATIONS Designed specifically for supplementary protection of semiconducting devices such as silicon controlled rectifiers (SCR’s), diodes,...
