Resistors reduce component count for HV applications

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 meters, measurement instruments and process monitors.

Volume-saving GDT selected for surge protection device

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 profile of its latest SPD to a mere 3.5mm wide.

Understanding ESR in electrolytic capacitors

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.

Topological insulators become magnetic at room temperatures

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 insulating magnetic film, creating a 'heterostructure'.
