Littelfuse – How to choose the ideal sensor for industrial automation applications


By Gwenn Gmeinder, Sensors Business Development Manager, Littelfuse Motion-control and automation systems for industrial use have to cope with the hazards of dirt and dust commonly found in factory settings. In addition, conveyors and pick-and-place systems can be subject to vibration and shocks which threaten the stability of the control circuit’s sensors. The sensing technology […]

Littelfuse – TVS diode arrays protect DC lines in powered USB interfaces


Littelfuse has introduced a series of TVS diode arrays which provide ESD protection for DC power lines in powered USB interfaces. The new SP11xx series employs Zener diodes fabricated in a proprietary silicon avalanche technology to protect each I/O pin in the interface. These robust devices offer high surge tolerance. In fact, surge density per […]

Littelfuse – New SiC MOSFET combines low switching losses, high efficiency and robust performance


Littelfuse has introduced its first Silicon Carbide (SiC) MOSFET. The LSIC1MO120E0080 has a voltage rating of 1,200V and offers ultra-low on-resistance of 80mΩ. Total gate charge is typically 95nC. It is optimised for high-frequency switching applications: its combination of very low switching losses and fast switching speed is far superior to the performance provided by […]

Littelfuse – Compact surface-mount fuse with current rating up to 100A helps save board space


The 881 series NANO2® fuse is a relatively small, surface-mount fuse which provides over-current protection for applications operating at high current values in a limited space. Such applications are mostly served today through the use of a single, large industrial fuse with a high current rating. In some cases, designers may implement over- current protection […]

Littelfuse – Surge protection module offers additional safety features for failure and fire hazards


The Littelfuse LSP10GIHP series of thermally-protected surge protection modules are self-protected devices for use in outdoor and commercial LED lighting fixtures. The modules are based on Littelfuse thermally-protected varistor technology. A built-in Thermal Disconnect function provides additional protection against catastrophic failure and fire hazards even under the extreme circumstances of varistor end-of-life, or exposure to […]

Littelfuse – Compact reed sensor offers various contact options


The 59022 Firecracker from Littelfuse is a cylindrical reed sensor available with a choice of Normally Open (NO), Normally Closed (NC) or Change-Over (CO) contacts. A magnetically-operated proximity sensor with hermetically-sealed contacts, the 59022 operates through non-ferrous materials such as wood, plastic or aluminium. Its magnetic principle of operation makes it well suited to use […]

Littelfuse – Varistors provide high surge protection at temperatures up to 125°C


The HMOVTM varistor series from Littelfuse is for applications requiring the ability to absorb high surge energy and to operate at high temperatures up to 125°C. The maximum peak surge current is rated at up to 10kA for an 8/20μs pulse. This is sufficient to protect against indirect lightning strikes, switching surge transients and abnormally […]

Littelfuse – 30A surge protection for broadband network connections


TThe SDPxxxxT023G6RP is part a series of SDP Biased thyristors providing over-voltage protection for high data-rate applications such as VDSL2, ADSL2, and ADSL2+ with minimal effect on data signals. The surface-mount SOT23-6 package of the SDPxxxxT023G6RP provides a surge capability which exceeds the requirements of most standards worldwide, as well as the recommendations for lightning […]

Littelfuse – Compact varistors handle peak surge currents up to 10kA


Littelfuse has expanded its LV UltraMOVTM series of varistors to provide over-voltage protection to applications with very high DC voltage and surge requirements. Voltage surges may be induced by interference from indirect lightning strikes, system switching transients, and abnormal fast transients from a power source. Littelfuse’s varistors provide a compact and dependable form of protection […]

Littelfuse – SiC Schottky barrier rectifier outperforms conventional switching diodes


Littelfuse has introduced the LFUSCD series of Silicon Carbide (SiC) Schottky diodes, which offers high efficiency, reliability and thermal performance in power-switching applications. When compared to standard silicon bipolar power diodes, the LFUSCD series diodes produce lower switching losses, accommodate larger surge currents without thermal runaway, and operate at higher junction temperatures. These features enable […]
