Default SMD component identification !

Hi again,

Attached is a photo for a similar component to a blown one in a faulty card I'm trying to repair. As an prehistoric technician, I'm not much familiar with SMD so, I do not know what are these two components.

I do contact EBCOS company and amazingly, the swift reply me, the yellow one is " tant chip capacitor" when I asked about its value and the identity of the black component, they gently excused that they can not help me.

Any body can help for the value of the yellow capacitor and the identity of the black one.

Thanks

107 = 100u 10v

22 35 = 22u 35v

Thanks for your help, for the black one, similar idea came to my minde, but the 2N diverted the whole things.

Is there any problem -except for the space- to replace them with the ordinary snap capacitors.

Thanks again.

colin nailed the values, both are tant caps, and the line indicates positive, unlike the line on a diode or aluminum electrolytic cap which indicates negative!

without seeing more of the board, can't tell you what an appropriate replacement, other than the exact same thing, would be. sometimes tant are used because of low esr, high frequency, etc. sometimes they're just used because they offer high capacitance in a small size.

Isn't it weird though that the negative end connects to the positive rail in a bridge rectifier.


Just kidding.

Hi
You can find tantalum caps in 10packs on ebay and they're very cheap.

The line on a diode indicate cathode (k) (kathode) NOT NEGATIVE - the cathode end of the diode may be connected to the negative rail or the postive rail of a circuit (or anywhere in-between), but the black or silver or red stripe or indent or dot or chamfer or symbol on a diode ONLY INDICATES THE CATHODE. Nothing else.

However in order for a diode to pass current the cathode has to be negative in relation to the anode. Thinking the diode cathode itself actually represents a negative voltage is a bad habit to get into like I think Colin was trying to say.
