Littelfuse exhibit SPD modules at electronica 2014

In A6.250 and B1.235, the company will be presenting recently introduced technologies, trends and components, as well as current and future industry requirements in markets such as electrical energy, consumer electronics, automobiles, commercial vehicles and industrial equipment. Littelfuse is also expanding into adjacent markets, such as power control and sensing platforms, heavy-duty switches for commercial vehicles and electromechanical sensors used in the automotive industry.

Speed2Design programme: Protect. Control. Sense

Littelfuse is currently entering into the next phase of its Speed2Design programme utilising www.Speed2Design.com as a central resource for electronics engineers to consult for expertise and solutions related to circuit protection. Safe and successful circuit design needs to include circuit protection as a key ingredient. The company adopted the theme 'Protect. Control. Sense' because of how vital circuit protection, power control and sensing products are to keeping the technologies people depend on operating safely and dependably.

Product highlights at electronica

LSP Modules
At electronica, Littelfuse will be presenting two product lines designed specifically to provide transient overvoltage protection for outdoor and commercial LED lighting fixtures. Constructed with Littelfuse thermally protected varistors, the LSP05 and LSP10 SPD (Surge Protection Device) modules provide robust surge current handling capability. A built-in thermal disconnect function provides additional protection from catastrophic failures and fire hazards, even under the extreme circumstances of varistor end of life or sustained overvoltage conditions. Applications include outdoor and commercial LED lighting.

Thyristors
Littelfuse Q6008xH1LED and Q6012xH1LED series alternistor triacs and Q6008LTH1LED and Q6012LTH1LED series QUADRACs for LED dimming offer robust solutions for power switching control of AC line-based LED dimmer applications. They are designed to work as the switching device in the dimmer circuit to vary the light output of new dimmable LED bulbs and strings. They are well suited to the needs of LED lighting dimmer designers who want to combine the widest range of operating parameters with high reliability and without degrading the dimmer’s performance. The low load current capability of these devices allows the creation of a single dimmer design that can handle all dimmable lighting loads: LED, CFL, and traditional incandescent.

Flange Mount Reed Sensors
Reed sensors are magnetically actuated proximity switches that are available in a variety of mounting options. The switching function is activated by introducing or removing a magnetic field. With the two-part magnetically operated proximity sensor 59145 and 59150, flying leads can exit on either the left or right hand side of the housing. The case design allows for screw down or adhesive mounting. Furthermore, sensitivity can be defined to meet specific customer needs.

Key benefits include no standby power requirement, operation through non-ferrous materials such as wood, plastic or aluminium, hermetically sealed, magnetically operated contacts that continue to operate long after optical and other technologies fail due to contamination. The main applications for flange mount reed sensors include position and limit sensing, security system switches, linear actuators, and door switches.

At the Exhibitor Forum in Hall B5, Bharat Shenoy, Director of Technical Marketing, Littelfuse, will be talking about surge protection for outdoor LED lighting. The presentation is scheduled to take place on 12th November, from 3pm to 3.30pm.
