Littelfuse iDesign Tool is the First Fuse Design and Selection Tool of Its Kind in the Circuit Protection Industry

Robust, web-based tool reduces time and uncertainty when selecting optimal fuse for application

CHICAGO--Littelfuse, Inc., the global leader in circuit protection, has introduced the Littelfuse iDesign™ Online Fuse Design and Selection Tool, a robust, web-based tool designed to help circuit designers identify the optimal electronic fuses for their projects. The Littelfuse iDesign tool, the first of its kind available from a circuit protection device supplier, was developed in response to requests from Littelfuse customers. It offers a fast, intuitive way to identify the best component for an application, find parts documentation, and order part samples for prototyping, all in one convenient package. To use the Littelfuse iDesign tool, simply register to create a free online account at the iDesign Login.

Unlike the simple parametric search tools or catalog-based selection charts many other circuit protection component suppliers provide, the Littelfuse iDesign tool walks users through a fuse selection process that quickly narrows the available options based on the inputs provided. The iDesign tool currently supports electronic, board mounted fuses used in a wide variety of applications, excluding system-level fuses, power fuses or automotive-style fuses. The iDesign tool's flexibility will allow Littelfuse to incorporate additional circuit protection devices in the future, so users should check back frequently for the latest additions.

Bharat Shenoy, the director of Technical Marketing for the Electronics Business Unit at Littelfuse, noted, "The iDesign tool is much more powerful than any simple parametric search of a parts database, which can often deliver either dozens of part number recommendations or none at all, depending on the parameters you input. Unlike those tools, which assume a lot of prior knowledge on the circuit designer's part, the iDesign tool is based on the calculations set out in our popular Fuseology Application Guide and combines them with the information in our fuse datasheets. That lets circuit designers make accurate fuse selections more quickly, simply, and cost-effectively than ever before. In real-life circuits, a less-than-optimal fuse selection can be dangerous and expensive, leading to premature failures, safety hazards, and warranty problems. The iDesign tool can ensure that the fuse chosen by the circuit designer is reliable and safe to use before it gets ever build into a product."

Shenoy continued, "In the past, selecting the right fuse for an application could be a very confusing and time-consuming exercise. But with the Littelfuse iDesign tool, we've turned what was once a pretty complex process into a quick and intuitive procedure that users at all levels of circuit design sophistication can understand easily. At every step of the selection process, tutorial buttons and notes guide the user. In addition, a Design Manager toolbar lets users create, save and re-load their selections, as well as share them with co-workers, simplifying collaboration on larger design projects."

US Digital - E4T Miniature Optical Kit Encoder

US Digital - E4T Miniature Optical Kit Encoder

US Digital is pleased to announce the launch of the E4T, their latest series of miniature high performance optical encoders. The E4T series delivers a marked performance increase over similar encoder models and designed to be an enhanced replacement for the E4P encoder series. The E4T utilizes state of the art transmissive optical sensing technology, and incorporates US Digital's own proprietary OptoASIC. Assembly of the E4T is simple and efficient and retains the previous E4P's form factor. Key features of the new E4T include: • Mechanically and Electrically Interchangeable with E4P • Improved Quadrature Signal Strength • 100 kHz Frequency Response • Transmissive Optical Design • Collet Style Push on Optical Disk Design (Patent Pending) • Simple & Efficient Assembly Process As with all of our products the E4T is designed and manufactured in their Vancouver, Washington USA facility and is available for purchase as of December 2014.
