Low capacitance TVS diode arrays offer better protection
Littelfuse has introduced a series of a low capacitance TVS Diode Arrays designed to protect high speed, differential data lines against Electrostatic Discharge (ESD), Cable Discharge Events (CDE), Electrical Fast Transients (EFT), and lightning induced surges.
Resistors reduce component count for HV applications
The WRM-HV series of precision metal film MELF resistors has been launched by TT Electronics. With over double the standard voltage rating and a value range from 340k to 3.4M, WRM-HV provides surge tolerant, high stability solutions for high voltage measurement and precision analogue circuits. For use chiefly in the market segments of industrial, instrumentation and medical, the resistors will be of particular interest to designers of energy mete...
Volume-saving GDT selected for surge protection device
Manufacturer and supplier of electronic components, Bourns, has announced that Phoenix Contact has selected the Bourns Model 2017 Series FLAT GDT for its TERMITRAB Complete product, which Phoenix Contact claims is the world's thinnest surge protection device (SPD). The space and volume-saving breakthroughs made in the Bourns FLAT GDT design are a major contributing factor that enabled Phoenix Contact to significantly reduce the size and prof...
High-speed device can be deployed on legacy cable systems
Marvell has announced the Alaska M 88E2180 Gigabit Ethernet transceiver, the world’s first octal multi-Gigabit Ethernet transceiver compatible with both the IEEE 802.3bz standard and the NBASE-T AllianceSM specification for 2.5 and 5 Gbps operation over CAT5e cables. This highly sophisticated IC will enable enterprises to quickly and cost-effectively migrate to multi-Gigabit Ethernet networking infrastructure.
Understanding ESR in electrolytic capacitors
Today’s microprocessor-based systems require power sources that deliver high current and ultra fast transient performance, with tight regulation. This creates a need for cost effective, compact capacitors with high capacitance values. Electrolytic capacitors are the solution of choice but it’s important to go beyond specifying capacitance and voltage to consider Equivalent Series Resistance (ESR) as a figure of merit.
The wirewound resistor - alive and kicking
The wirewound resistor – alive and kicking, by Phil Ebbert, VP Engineering, Riedon. As with every other type of component, the techniques for fabricating resistors have changed over the years as new technology and materials emerge.
Versatile switches suit host of applications
The KMR Series of microminiature top-actuated tactile switches from C & K is now available at TTI. The Series includes IP40, IP67 and ultra-low current versions to suit a wide variety of different markets and can be designed into many applications, including those exposed to harsh environmental conditions.
Thin film resistors have wide customisation capabilities
Manufacturer and supplier of passive components and interconnect solutions, AVX, has released the new WBR Series thin film wire bond resistors. Diced to small 0202 (0.02x0.02”) chip outlines with tight dimensional tolerances (±0.003”), WBR Series top-contact, bottom-isolated resistors are ruggedly constructed, rated for up to 250mW DC power, and deliver stable and high-reliability performance in low profile packages.
Topological insulators become magnetic at room temperatures
In the world of electronics, where the quest is always for smaller and faster units with infinite battery life, topological insulators (TI) have tantalising potential. In a paper to be published in Science Advances, Jing Shi, a professor of physics and astronomy at the University of California, Riverside, and colleagues at MIT and Arizona State University report they have created a TI film just 25 atoms thick that adheres to an ins...
Battery shunt resistor offers improved accuracy
A new Power Metal Strip battery shunt resistor has been announced by Vishay Intertechnology, featuring two sense pins that offers a 36W power capacity in the 8518 case size. With low resistance values down to 50µΩ, the Vishay Dale WSBS8518...20 increases accuracy and lowers costs compared with Hall Effect current sensing solutions, while its sense pins assist in PCB mounting and provide consistent contact point location.
