Burned the Futaba FF9 D201/L210

[wland]

hello guys.

Playing with the trainer port of my Futaba FF9 a component "D201(marked S5)" seems it burned and L210(marked 4R7J) also burned. :eek:
My transmitter is normal fortunately.
Does anyone know what that component might be?

The blue epoxy coated L202 and L204 are inductors so L210 is likely to be a 4.7 uH (5%) inductor and D201 a diode or dual diode.
You are in a better position to tell.

You mean D201 is SOT-23 type SURFACE MOUNT SCHOTTKY DIODE and L210 is SMD 4.7uH 0.5% inductor.

Futaba don't give me answers.
Thanks feegie park

I'll bet there's some part of that radio that isn't "normal". I'd check the trainer functions carefully before I tried using it with a buddy box.

I guess trainer port is abnormal.
but I have no problem with flying.
which element can I buy?
thanks David.
