SCHURTER SMD fuses for LED technology

LED technology has totally revolutionized the lighting market. These devices bring countless advantages, but their sensitive electronic circuits require suitable protection. SCHURTER offers the optimal solution for every need.

Compared to other sources of lighting, LEDs offer clear advantages: They consume up to 90 percent less energy than standard incandescent bulbs. Their service life can extend as long as 50,000 hours. They achieve 100 percent luminosity immediately after being turned on, and total failures are practically unheard of. Due to their small dimensions they also save space, and thanks to a wide selection of colors they are very versatile in terms of applications.

The requirements on the primary protection of LED lighting systems are very high. The simplest and most reliable way to achieve primary protection is with a midget fuse. Such fuses require a sufficiently high I2t value to ensure they are not tripped by inrush current peaks. They also require high breaking capacity so they can, for example, interrupt the current path in case of a short circuit. 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 fulfills these exact requirements in an optimal way with the UMT 250, UMF 250 and UMT-H SMD fuses: They 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. The 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 demandd.
