I got this prob and if there is someone who can me help I will bless him whole my missery life


My Irda was broken, actually SMD resistor connected to infrared LEDs and I need to find out what ohms there should be. There is link to picture which is describing what resitor I'm missing. For sure in red circle and I'm not sure if there is other resistor in green circle.


thanx a lot for any help

Only problem is I dont actually have it, so no reading possible. Maybe someone could provide me Irda tranceiver
type so I could find out ohmage in datasheet tech spec.

Why don't you measure the ohmage with a tester after taking it off? (

I'm sorry if I expressed my problem badly it's my poor english but I have not this resistor because when my Jornada fell down resistor was pulled out

It sounds crazy but I can't find it in Jornada so that's why I can't measure it.
