Reading capacitance on SM capacitor
Hi, I'm looking at a laptop (Toshiba Sat 3000, to be specific) motherboard that having some SMD suspecting leaky capacitors; Some basic questions if someone can bring me up-to-date to the world of surface mount device, that would be nice: * There are four of them in parallel; ohm reading both way, in circuit, about 50 Ohm. They are around the power charging area, and the circuit having a blown fuse. Would this sound like a strong posibilty for leaky cap ? (I can take them out one by one for sure...) * The capacitors are the good size ones in the SMD world (6mmx4mmx3mm); There is + sign printed on one end, and the printed note say "220" on first line and "g14" the next line. Would that be 220 pF ? Seem little for that size... Thanks for any advice. Cheers, |
