Chip capacitor array has benefits

7 March 2007 Passive Components

Not so long ago, Murata's 0805 chip capacitor was small and difficult to handle. True, it was rated at 50 V d.c. and 125°C, but most applications do not need those ratings today and today's machinery handles the smallest parts with precision.

Now, the company's GNM214, the same size as the 0805 (2,0 x 1,25 x 0,95 mm), is a four-capacitor array. This simple change reduces both mounting cycles and investment in machinery by 75%, according to Murata. At the same time, it reduces the volume of the four capacitors from a nominal 9,5 cc to only 2,375 cc. What this means is less machinery, less labour, less investment, less space - a win-win choice.

Since four capacitors in a row may not be that convenient, Murata offers two capacitor arrays in the familiar 0805 GNM214 package, and in both the 0504 and 0302 packages (1,37 x 1,0 x 0,65 mm and 0,9 x 0,6 x 0,45 mm). And obviously, the laws of physics impose limits on the values that can be achieved in a given package.
