100µF 63V conductive polymer electrolytic capacitor in 10 x 12.5mm SMD case

Panasonic is to add a smaller case size to ZS-Series of SMD conductive polymer hybrid electrolytic capacitors. Remaining 10mm in diameter, the new case is 12mm rather than 16mm tall. “The effect of the smaller size of ZS-series is to deliver higher performance while keeping the premium PCB real estate in check with a few ...

Commercial silicon solar reaches 21.4% efficiency

LG Electronics’ latest commercial solar panel can reach an efficiency of 21.4%. It is the LG370N1C-N5, styled a ‘premium’ product by the company – an n-type monocrystalline panel producing 370W max from its 1.7 x 1m surface (irradiance 1,000W/m2, 25°C, 1.5AM). Open-circuit under the same illumination it delivers 41.8V, and short-circuit the figure is 10.92A. Maximum ...
