Infrared capacitor type?

[Natalie Wilkie]

Hi All,

When using the circuit from Manual 2, page 78 the infrared circuit I was wondering does it matter what type the 4.7uF capacitor is. I was thinking it should be an Electrolytic type or maybe a Tantalum.

Can someone enlighten me on what it should be and why.

Thanks
Nat

I've used both small "tube" electrolytic and Tantalum.

So far, no problems.

Any type will do, its just a power supply decoupling capacitor. 4u7 is recommended by the manufacturers datasheet and so should be used, but in reality in most setups you will find the circuit also works without it.
