Decades ago, perhaps one of the first practical lessons a circuit designer would learn at the outset of their career was the art of decoupling using a combination of different value capacitors. A good mentor would explain that because of their physical characteristics, different value capacitors were optimal for filtering different frequency bands. This author even remembers designing a decoupling network for a 25W buck converter that included the parallel combination of ceramic capacitors of 1 μF, 0.1 μF, 0.01 μF, and 1000 pF in value. The network performed well once the component leads were made short enough! blog.Mini-Circuits.com July 31, 2023

What has been a catalyst in the development of the indigenous LED ecosystem? From Make in India, Street Lighting National Programme (SLNP) to Unnati Jyoti by Affordable LEDs for All (UJALA) scheme all these government policies are known to have set the Indian LED industry to a new benchmark. But lack of skilled manpower, high capital investment, lack of infrastructure, and dependence on imports are the heat that the LED Industry in India has been facing. To understand the critical aspects, the viability of Government initiatives and how truly India can become a hub for electronic systems design and manufacturing, TIMES TECH BUZZ in its cover story brings the eloquent discourse of… TechTimes.in June 2023
MIL-PRF-32535 for discrete MLCCs has led to the discussion of stacked ceramic capacitors based on BME technology. Stacked ceramic capacitors are multiple discrete multi-layer ceramic capacitors (MLCCs) terminated onto a common lead-frame for through-hole or SMT operations. They capture many of the inherent benefits of MLCC technology, like a low-loss material set, low ESR (equivalent series resistance), and higher reliability. Typical applications like switch mode power supplies need larger capacitance values and current capabilities. Stacked MLCCs compete with discrete electrolytic capacitor technology in terms of capacitance range but have an advantage in terms of voltage and temperature capability, which naturally increases their reliability, thereby making this a preferred technology for defense applications despite its higher price point compared to electrolytics.
A growing number of applications, ranging from solar power converters all the way to miniature power supplies for highly complex processing cores, are starting to capitalize on the benefits of aluminum electrolytic capacitors. Aluminum electrolytics are also increasingly used to satisfy miniaturization demands in complex power tree applications like FPGAs powered by multiple voltages. And while it’s true that aluminum electrolytics also come with disadvantages, several of the more well-known ones are no longer true, and other perceived disadvantages can be reduced or eliminated by selecting newer components engineered to overcome some of the technology’s traditional shortcomings.

There are many places you could implement energy-harvesting (EH) sensors in factory automation and measurement applications. For example, remote or hard-to-access applications that currently rely on physical equipment inspections for status updates could be converted to a wireless sensor network, provided that there is enough energy nearby to capture and that the measurements are sufficient for making an informed decision.

You might think you know how film capacitors fail and degrade in capacitance over time – self-healing due to surges, right? WRONG! Capacitor expert and AVX Fellow Ron Demcko confirms what’s really going on after a teardown of some failed and one good polypropylene X class capacitor. EEVBlog July 21, 2022
As e-mobility continues to expand, the automotive industry is presented with many design challenges, like fitting more robust electric motors, controls, and modules into a vehicle while maintaining reliability and signal integrity and reducing weight—where possible—to extend battery life and driving range. designing-electronics.com (DENA) May / June 2022
Capacitors are among the most widely used passive components in electronics, so naturally they find their way into many applications in harsh operating environments. In certain applications such as those in oil logging, jet aircraft, nuclear power generation, and other industrial applications, these components are subject to extremely high temperatures, often somewhere in the range of 180°C to 300°C. how2power.com March 2022
