Can anyone help me identify these components

Hi, I need help identifying the 3 components I have highlighted.

Also it would be great if somebody could point me in the direction of where to buy some.

Many thanks in advance.

The two at the left are probably ceramic capacitor. The one to the right a resistor.
432 means 43*100 OHm = 4.3kOhm
The capacitors have no visible marking, it is probably on the underside. No chance of identification without de-soldering them.

I have de - soldered many of these and there is no marking anywhere.

Thanks

We use a lot of caps like this at my work, and generally the only way we can identify them is to desolder them and check them with a capacitance meter. If you measure them on the PCB you won't always get a proper reading depending on what else is on the circuit. Hope this helps

Yep, I'd agree with that.

Thanks for the info.

So if I test them on a capacitance meter and came back with the results, do you think you would be able to identify them?

Thanks

I think I could certainly try, and if I can't then I'm sure someone else on the forum could.

Once you've tested them, you've identified them. Capacitance and size are relvant parameters. From the picture I don't think these are special with regard to voltage. Typically this size is rated 50V, max. 100V.

If it helps, these are on a key fob with a 3.6v battery.

My apologies, I thought you meant.identify them as in 'what are they doing in the circuit?' If not, then as above, once you have the values you're done.
