Produced in industry standard 1206 chip sizes, the fuse line offers small size, high reliability, strong arc suppression characteristics, and some of the highest current ratings available in the 1206 form factor. Intended for DC power applications of up to 63VDC, slow blow fuses help provide overcurrent protection on systems that experience large and frequent current surges as part of their normal operation.

Available in current values ranging from 1.0 to 8.0A, such applications include protection of power supplies, capacitor filter banks, LCD backlight inverters and electric motors. Raychem fuses enhance electronic system reliability without compromising protection against high current fault conditions and feature clear time characteristics of: 4 hours minimum at 100% of rated current, 120 seconds maximum and 1second minimum at 200% of rated current, 3 seconds maximum and 0.1 second minimum at 300% rated current, and 0.05 seconds maximum and 0.002 seconds minimum at 400% of rated current.

The Raychem Circuit Protection fuse’s monolithic, multilayer design helps provide some of the highest current ratings available in the 1206 footprint and enhances high temperature performance in a wide range of circuit protection designs. The RoHS-compliant device is designed for operating temperatures between –55ºC and +125ºC, and withstands soldering temperatures of up to 260ºC for 60 seconds maximum.

“The new slow blow fuses are the next step in Raychem’s expanding line of single use overcurrent protection devices,” said Matt Chamberlain, Raychem Fuse Product Marketing Manager. “Our wide range of available currents offers designers a more complete solution for protecting electronic systems with very dynamic current requirements.”

The Raychem slow blow surface-mount fuses are available on 7-inch (178 mm) reels for compatibility with high-volume assembly methods and are UL recognized.
