In recent years, renewable energy options have become much more efficient and feasible. This has led to a large adoption of these applications, an especially poignant point in the face of current environmental issues. However, just like all other power generation methods these applications require resistors.

The complete series of Electrocube RC Networks ‘Arc-Suppressing’ Resistor-Capacitor (RC) Circuits is available now from New Yorker Electronics. Also known as resistors, resistor-capacitors or RC filters, Electrocube’s RC Networks are designed to prevent or substantially minimise the occurrence of arcing and noise generations in relay and switch contacts.

LEM has announced the development of the Rogowski coils range to measure current up to 300,000A AC with accuracy class 0.5. The ARU range achieves IEC 61869-10 class 0.5 without the need for additional components such as resistors or potentiometers to calibrate the coil, which can drift over time.

Addressing PC board layout can reduce footprint, EMI and noise. Tony Armstrong, Analog Devices, explains how Silent Switcher architecture can help power designers

Pushed by legislation and pulled by the demands of an excited marketplace, LED lighting has quickly become dominant, serving almost every illumination need from functional to decorative. Its success has transformed production of lighting fixtures away from traditional electrical wiring challenges and now demands electronic design knowhow and manufacturing capabilities.

LEM has expanded its range of miniature, integrated circuit sensors range for AC and DC isolated-current measurement with the introduction of the HMSR series. Despite their small size, the components can handle overload current bursts of up to 20 kA (8-20µs surge test profile), such as those that occur in photovoltaics applications while still providing a reinforced isolation. Products in the series are designed to measure currents of up to...

The TMP390 device from Texas Instruments is part of a family of ultra-low power, dual channel, resistor programmable temperature switches that enable protection and detection of system thermal events from –50°C to 130°C. The TMP390 offers independent overtemperature (hot) and undertemperature (cold) detection.

Torex Semiconductor has launched the XCL303/XCL304 as a new series of inductor built-in negative output voltage micro DC/DC converters. The XCL303/XCL304 series are small coil-integrated negative voltage micro DC/DC converter IC. Increased oscillating frequency to 2.5MHz and by adopting the small package CL-2025-02(2.5x2.0x1.0mm), the mounting area is reduced by approximately 78%.

LEM has expanded its range of miniature, integrated circuit sensors range for AC and DC isolated-current measurement with the introduction of the HMSR series. Despite their small size, the components can handle overload current bursts of up to 20kA (8-20 us surge test profile), such as those that occur in photovoltaics applications while still providing a reinforced isolation.

In August 2019, Ipswich Hospital plunged into darkness after it was hit during a 15-minute UK-wide power outage. The trust revealed that the disruption caused the unit’s circuit breaker to fail, briefly cutting the electrical supply to outpatients and the x-ray department. Luckily, the hospital’s back-up generators took over and prevented risk to both patients and life-saving medical equipment.
