IR transmitter circuit, help

#1 Post by happytriger2000 » 26 Mar 2012, 02:55

Hi,
I'm quite new to Diptrace, and just now I created a schematic of a simple IR transmitter circuit, but not sure which capacitor symbol to use under Discrete for 3.3pF Ceramic 1,500pF / .0015uF Ceramic / Mylar 152, please open attachment for Image file and diptrace schematic file, please suggest of fill in the suitable cap, thanks

The CAP* parts in the Discrete library end in a number, which is the distance between pins in mil.
It does not really matter as such which component you choose in the schematic part. You can always change the pattern that is attached to a component.
I suspect this is really what you're asking,

CAP100 should be appropriate for a small 3.3pF ceramic cap. The others, it really depends what components you want to use. You can also just draw your own patterns. It's very easy!
