Panasonic has introduced the ZV Series – an Electrolytic Polymer Hybrid capacitor with advanced characteristics. It achieves a maximum Ripple Current (3.3~4.6 Arms) – claimed to be approximately 50% higher than comparable case-sizes. While comparable capacitors usually come up with a ESR of around 16 mΩ at 35V, the ZV series has an ESR of 12 mΩ at this voltage ...
Murata has announced multi-amp miniature automotive SMD inductors that are over 30% better than their forebears. Measuring 2 x 1.6 x 1.2mm (0806 or 2016), there are two types: DFE2MCPHR33MJLLQ 0.33μH ±20%, 0.018Ω 5.1A max (6.4A typ) at 40°C rise 6.9A max (8.1A typ) at 30% inductance change DFE2MCPHR47MJLLQ 0.47μH±20%, 0.022Ω 4.4A max (5.5A typ) at 40°C rise 5.4A max ...
ITG Electronics will feature 600Vac common-mode chokes at APEC in February, which offer “higher voltage ratings and more robust hipot Isolation between two windings – the products address increasing demand for industrial, under-the-hood inverter applications”, it said. That hipot isolation is 2,500Vac. There are two series: C301306H measuring 44 x 48 x 34mm, and C301369H at 34 x 35 x 26mm. ...
The SiT5503 Elite X Super-TCXO uses MEMS technology to replace bulky quartz OCXOs to offer a device that is four-times smaller with four-times lower power consumption for enhanced timing performance in data centres and 5G infrastructure. The judges were impressed with this innovative timing product with a wide range of applications. Highly commended – STMicroelectronics Shortlist * Harting – Han ...
Spectrum Control has introduced a family of modular power EMI filters for designs meeting MIL-STD-461. 52F1825 filters operate across -55° to 75°C and the “rugged design includes a convenient, environmentally sealed input interface that withstands moisture, dust, and other contaminants to ensure durability and longevity”, according to the company. The models come with a 89 x 127mm footprint in a ...
Kemet has introduced three automotive grade supercapacitors. “Optimised design and materials enable a service life of up to 1,000 hours at 85°C or 105°C, and the components meet the special requirements of the 85°C, 85% relative humidity, 1,000 hour test [‘THB test’] for the automotive industry,” according to distributor Rutronik, which is stocking the parts. “Thanks to their characteristics, the ...
Epishine, the Swedish indoor solar power specialist, and Nichicon, the Japanese capacitor manufacturer, have come up with a self-charging battery concept. The idea is to combine Epishine’s solar cells and Nichicon’s LTO-batteries in an integrated solderless autonomous power product which is an alternative to disposable and re-chargeable batteries, reducing time-to-market and cutting down on product development costs. “We’ve created a ...
The AEC-200 Y2 class interference suppressor capacitors by Cornell Dubilier that meet a 2,000 hour THB (temperature, humidity and bias) life test are available from New Yorker Electronics. The MYH series were subjected to 2,000 hours THB testing at 85°C, 85% relative humidity at rated voltage, which is twice the industry standard test hours required to meet IEC 60834, Class ...
Capacitors are among the simplest of electronic components – in theory – but the practical implementation is becoming more complex, says Christian Merkel. Capacitors are two conducting plates, separated by an insulating dielectric layer. They hold charge when a voltage is applied to them and give up that charge when the charge-carrying electrons are given a route to flow off ...
Electrocube has created a series of metallised polypropylene film capacitors for high power inverters in military and commercial, land and sea, applications. Voltage ratings of 400, 600 and 1,000V are available, and capacitances from 100nF to 10μF, plus 15 and 20μ in the 400V range “Able to handle high surge currents without degrading, Electrocube’s 985B is a rugged, non-inductively wound ...
