Hey guys, I'm new to this site but it looks very helpful. Anyways a part broke off of a speed control for my RC airplane I crashed and I'm trying to find it's replacement. I've enclosed a picture, does anyone know what it is?
47 may mean 47micro Farad
the 101 should be 10x10^1=100V?
if so, it looks like a surface mount capacitor, tantalum as stated in previous post.
measure the width and height as shown on your picture. What are those dimensions.
(USE accuracy, is it 0.08x0.06" (0806 size) or 1206 (0.12x0.06") or what.
The size will nail it. Find a local electronics store, for technicians and hobbyists, call and ask for a smt (surface mount) capacitor with your measured dimensions, or take it in. Mail order works to, but for a $1 part in onesy-twosy quantities local is good.
If you have access to a capacitance meter function, measure it's capacitance.
If just a VOM/DMM is available, use it in Resistance range. You should get no reading in any resistance range. Remember to also test by reversing the DMM leads for a second measurement, in case the line on the part is a diode's cathode?
If you suspect it's a diode, again go to the Ohm range around 2K to 20K. If it conducts with the neg/black lead hooked onto the part's polarity line, it is a diode. Different story in that case. If you get the same resistance value, even if you change ranges, then it looks resistive or a resistor.
