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 ...

Rohm has developed its first silicon capacitors, the 400 x 200 x 185μm ( 01005, 0402 metric) BTD1RVFL series which covers 100pF to 1nF. “The mounting area is reduced by approximately 55% over general 0201 [0603 metric] products to just 0.08mm2.” according to the company. “Moreover, a built-in transient voltage suppressor protection element ensures high ESD resistance.” They are rated ...

At 160µm tall, Murata is claiming to have the thinnest automotive-rated 1µF capacitor, which also measures 0.5 x 1mm. To reduce inductance, it has its terminals along the long sides – so called ‘reverse’ construction. Rated at 2.5V and having a maximum height of 180µm, LLC15SD70E105ME01# is one of only two membeds of a new family that the company has ...

Samsung Electro-Mechanics is aiming at automotive powertrains and safety systems with a 10µF 50V MLCC (multi-layer ceramic capacitor) in 3.2 x 1.6mm 1206 packaging. “Thanks to the application of proprietary ceramic and electrode material atomization, alongside ultra-precision lamination, the company was able to create the 10µF MLCC in 1206 size at 50V rating,” according to the company. “Importantly, the new ...
