Hitano, right O? left O, o NO?

07/28/2007 5:49 PM

I'v got a problem with the correcet wiring of the Hitano capacitors, I'm using Axial capacitors that only has a negative symbol on one side of the capacitor and an arrow pointing to the other side to indicate the positive and negative poles of the capacitor. The problem is, the arrow moves away from the negative, so that I'm not sure which side is which when it comes to wiring it. right hand rule says the arrow should point to the negative. have you ever used the Hitano capacitors (the ones with the arrows i.e.(-)==>)?

my multimeter isn't sensitive enough to pick up pico or micro farads, so I can't even test it out.

anyone ever used this capacitor before? and knows what the logic behind that negative sign with arrow the otherway?

my best guess is, wire negative to negative

Hmmm, I would ignore the arrow. E.G. minus sign will be negative end which you wire to most negative part of circuit.

Have you looked for the manufacturers data sheet on their website (assuming they have one)

But I reserve the right to be wrong.

the thing is, what if the arrow points to the negative end?

already looked at data sheets, no help. wrote to manufacturers, no reply yet. tomorrow, I can ring Stan the resident master at RS, and ask him.

I think the symbol use by Hitano, in this case is rather stupid... not to metion a waste of ink. a simple - & + is far more effective, effcient and needs no deciphering.

Hey Santa, if you reading these posts, "and I'm being a good boy" so can I please have a new multimeter, one that will deal in pico farads?

lol

Best thing is to write to the manufacturer and get their confirmation andthis may also result in their knowing that people face such problems and corrective action is needed.

best of luck

Chife,

The lead that this designation is pointing to is the negative lead and should be connected to the lower votage point.

If you look on their WEB page you can view a radial cap and see that the short lead has the same designation and it points to the shorter lead which is always used to ID the negitive plate.

This is from their ECR datasheet: I would guess that if there is a shorter lead (as others have said) it's always the negative.

I think it`s the ECA-SERIES because he says he is using an axial type. So the plus side will have a crimp mark.

Thanks Uwe,

Then this is the picture from the datasheet:-

Yeh, can is negative.... (usually, I think, allegedly, terms and conditions apply etc)

the can side of the Cap is always Neg, mainly due to the fact it could come in contact with chassic gnd

Wow Randall,

thank you very much, I don't know where you found that data sheet, but that's exactly what I needed to know. I have the other data sheet, but as you can see they don't vary the lengths of the leads of this particular variety of Axial capacitors. what that diagram indicates is that the arrow actually points to the negative side. therefore the positive lead situates on the same side as the negative sign.

thank you,

I'm rather impressed by the help.

cheers all.

can I get a link to that data sheet please?

would like to see if the range values are the same as the one sided lead end variety.

I tried to log onto the Taiwan site before. It took ages and I didn't hook into it for some reason. I could only get onto the Hitano.com site, and silly me thought that it would contain everything that was on the Taiwan site. so I was only able to get data on the radial capacitors.

anyway, I have the data sheet now, and once again, thank you for your help Randall.

Buy something better.... panasonic high ripple, 105 degree or something equivalent, each time I dealth with Hitano, got into problems. They have a short life, they won't puff but will somehow dry out.

And, btw, use the shorter pin as negative, don't trust the arrow.
