‘Capacitor’
An Electronicstalk guide
Start with the news release
LT3758 generates positive and negative voltages from
Linear Technology Corp, which we summarised at the time by saying "Linear Technology has brought out the LT3758, a high-input voltage DC/DC controller for boost, flyback, Sepic and inverting power-supply applications.".
Several months prior to that,
we featured the news release Low-power DAC for portable applications from
Wolfson Microelectronics: "Wolfson Microelectronics has launched the WM8912, an ultra-low-power DAC designed to extended playback time, reduce system cost and enhance audio performance in portable applications.".
In January 2010, we covered the news from Kemet Electronics
- take a look at Kemet parts offer higher capacitance values
which says: "Kemet has added part types to its GR900 ceramic-capacitor series, offering higher capacitance values for defence and aerospace customers. ".
Take a look also at the news release from AVX, Capacitor range includes 6.3V parts in C-case,
as well as Compact DC/DC converter features built-in Mosfets from Maxim Integrated Products,
and Murata technology reduces MLCC damage from Murata Electronics (UK).
