TE Circuit Protection announces the 2410SFV family of 20 AC/DC fuses featuring current ratings from 0.5A to 20A. 2410SFV fuses are said to be available in an ultra-thin (6.1x2.5mm) SMD package and claim to offer I2t characteristics as high as any similar SMD device on the market.

The 2410 fuses help provide secondary-side circuit protection, conserve board space and reduce design costs in a broad array of high-voltage, high-current designs. Typical applications include home appliances (LCD TV LED backlighting, LCD TV CCFL backlighting) and LED lighting, as well as office automation, industrial and medical equipment.

The 2410 fuses also offer a nominal cold resistance (DCR) from 0.0034Ω to 0.231Ω and a high-interrupt current from 50A to 300A. Rated for operation at temperatures ranging from -55�C up to 125�C, the fuses' high-inrush current withstand capability minimizes nuisance tripping during transient overload conditions.

As wire-in-air (WIA) fuses, the 2410SFV products feature a straight wire configuration. As surface-mount devices they provide a rugged, single-piece package that speeds assembly time and is compatible with standard pick-and-place SMD processes. The company also claims that the 2410SFV fuses' structure minimizes the risk of the end cap of the device becoming dislodged, a feature not offered by most competitive devices. In accordance with industry standards and trends for "green" products, the fuses are 100 per cent lead- and halogen-free and are RoHS-compliant and UL listed.

"Today's consumer, appliance, lighting, power and telecom industries increasingly demand designs that save board space and assembly costs and also meet stringent performance, safety and environmental requirements," said Jason Zhao, senior product manager. "These new AC/DC fuses offer a wide range of cost and performance benefits. In addition to providing a comprehensive selection of 2410SFV fuses with market-leading features, TE Circuit Protection offers global design support to help applications engineers identify the best solution for their design challenges."

The 2410 fuses are available now. Pricing is Rs.24.55 ($0.55) for 2K units with delivery of 8 weeks ARO.
