Further, a compact design is important because power supplies for LEDs are kept very compact. Finally, fuses for the primary protection of LED lamps must guarantee reliable protection over long operating periods and at high temperatures.
Schurter’s UMT 250, UMF 250 and UMT-H SMD fuses are very robust in handling high inrush current peaks thanks to their time-lag and quick-acting characteristics, a high I2t value and high breaking capacity of up to 200 A for the UMT 250/UMF 250 and 1500 A for the UMT-H. Their compact dimensions make it possible to use the SMD fuses even in devices where space is very limited. Reliable tripping over a large temperature range during their entire service life, a low voltage drop and an attractive price/performance ratio make the UMT-H, UMT 250 and UMF 250 excellent choices wherever quality and reliability are in high demand. The UMT 250/UMF 250 fuses come in 34 rated currents from 50 mA up to 10A while the UMT-H fuses come in 29 rated currents from 63 mA to 30 A. All come in a square design for easy PCB assembly and soldering. They are Halogen-free and RoHs compliant.
