Stackpole's AEC qualified RTAN series utilises tantalum nitride technology to provide moisture proof precision chip resistor performance. The RTAN film passes biased humidity testing at 85oC, 85% relative humidity, and ten percent bias with very little shift in resistance.

Resistors are commonplace power components in industrial buildings - but their use is not limited to the factory floor. In many industries, resistors play a vital role in the power management of electrical equipment. Here, Simone Bruckner, Managing Director of Cressall, explores the applications of resistors beyond the four walls of industrial buildings.

Changes in DC/DC converter technology have introduced new materials, digital control and smaller form factors, explains Lars Foerster, DC/DC business development manager, EMEA, TDK-Lambda

The TL431 and TL432 devices are three-terminal adjustable shunt regulators, with specified thermal stability over applicable automotive, commercial, and military temperature ranges. The output voltage can be set to any value between Vref (approximately 2.5 V) and 36 V, with two external resistors. These devices have a typical output impedance of 0.2 Ω. Active output circuitry provides a very sharp turn-on characteristic, making these device...

Year-on-year, the market for electric vehicles (EVs) continues to grow. As the G7 commits to the target of reaching net zero carbon emissions by 2050, actually achieving these lofty goals will rely on all sectors adapting to encompass these green ambitions. In transport, many people look to EVs as a means of reaching national targets. Here, Steve Hughes, Managing Director of REO UK, discusses the growth of the EV industry.

High efficiency current sensing is commonly done using low resistance value resistors. However, as resistance values are reduced, the measurement error due to lead resistance becomes significant. For applications requiring high efficiency with the best possible temperature accuracy, four terminal metal element current sensing products are the ideal choice.

Thanks to the health and wellness scene, the term ‘grounding’ has taken on a whole new meaning. Connecting directly with the Earth’s surface by walking barefoot is thought to enable the ground’s free electrons to restore the body’s energy balance, alleviating illness. Similarly, in electricity transmission, earthing stabilises the electrical system, helping to prevent damage from earth fault currents. Here, Martin Ni...

Solar power is currently the UK’s third largest renewable energy generator, but inefficiency challenges its growth. Here, Simone Bruckner, Managing Director ofpower resistor manufacturerCressall, has explored how solar panel efficiency can be improved to increase its supply to the grid.

LED-based lighting is increasingly popular in automotive applications like headlights and rear lights. These applications use an LED driver circuit, with the goal to maintain constant current. LEDs in modern automotive rear lights generally require current below 150mA which, given electromagnetic interference (EMI) and cost considerations, has made a linear LED driver a more appealing solution than a switching regulator. Michael Helmlinger, Syste...

Stackpole's RMCS series now offers a 2W power rating in a 2512 chip resistor size as the RMCS2512 ... -HP. This option doubles the standard 2512 power rating and allows for the RMCS-HP to be used for higher power applications that may have used a different technology previously.
