Polymer alloy capacitor film with 4× energy density up to 250 °C
A Penn State–led team has developed a new polymer “alloy” capacitor film that stores up to four times more energy than today’s state-of-the-art polymer capacitors while operating reliably up to 250 °C (482 °F). This breakthrough could have major impact on power electronics used in electric vehicles, data centers, space systems and high‑temperature energy infrastructure. […]
Embedded capacitors improve AI/HPC power delivery
Empower has launched three embedded silicon capacitors (ECAPs) for AI and high-performance computing (HPC) processors. The portfolio includes the EC2005P (9.34 μF in a 2×2-mm package), EC2025P (18.68 μF in a 4×2-mm package), and EC2006P (36.8 μF in a 4×4-mm package). These components are designed for integration into processor substrates to support elevated current density and fast transient […]

Bourns Extends Multilayer Chip Inductors
Bourns has released four new multilayer chip inductor series – CE0603G, CE0603M, CE1005Q and CE1608Q – aimed at compact RF and wireless applications where footprint, high‑frequency performance and reliability are critical. The families span very small 0603 metric up to 1608 metric sizes and cover inductance values from sub‑nanohenry up to hundreds of nanohenry, giving […]
Burning power lines
There was one heck of a scary item in the news recently. The following screenshots were taken from a video that was recorded in the teeth of recent inclement weather. Overhead power lines had actually caught fire. Figure 1 Overhead power lines that caught fire during inclement weather in Brooklyn, NY. It looks to me […]

Modelithics MATLAB Library for RF and mmWave Passives
The Modelithics Library for MathWorks MATLAB provides an extensive set of high‑accuracy, measurement‑based models for RF, microwave and high‑speed designs that rely heavily on passive components such as capacitors, inductors and resistors. For design engineers, it bridges the gap between ideal schematic elements and real‑world component behavior on specific substrates and pad geometries. This can […]
Logarithmic amplifiers: A quick tour of theory and practice
In this post, we will take a gentle dive into logarithmic amplifiers—commonly known as log amps—those quietly powerful circuits that work behind the scenes to decode exponential signals and tame wide dynamic ranges. Log amps: Basics and building blocks To set the stage, a logarithmic amplifier is an electronic circuit that produces an output voltage […]
