Multilayer chip fuses

18 April 2018 Circuit & System Protection

Bourns has released several new SinglFuse families of multilayer SMD chip fuses for time-lag, fast-acting and slow-blow application requirements.

The SF-0603SPxxxM and SF-1206SPxxxM time-lag models come in 0603 and 1206 footprints with 32 V d.c. and 24 – 63 V d.c. ratings respectively. They are rated for current of 1,0 to 8,0 A, and are intended for applications such as PC and LCD monitors, portable memory, gaming systems, cellphones, digital cameras, battery chargers and set-top boxes.

The fast-acting SF-0603FPxxxM comes in an 0603 package rated for 500 mA to 5,0 A and 32 V d.c. It provides circuit protection for PCs and monitors, server farms, portable memory, cellphones and tablets, digital cameras, gaming systems, set-top boxes, drones and robotics, white goods, battery chargers and industrial controllers.

The slow-blow SF-0402SxxxM, SF-0603SxxxM and SF-1206SxxxM series, in sizes 1005 (EIA 0402), 1608 (EIA 0603) and 3216 (EIA 1206), have respective current ratings of 500 mA to 4,0 A, 500 mA to 6,0 A and 500 mA to 8,0 A, and voltage ratings of 24 V d.c., 24 – 63 V d.c. and 32 – 63 V d.c. Typical applications are PC and LCD monitors, portable memory, gaming systems, cellphones, digital cameras, battery chargers and set-top boxes.

All the parts are UL listed, RoHS compliant and halogen free.
