Hi--
I'm sure this question gets asked sometimes, but I haven't been able to find a clear answer.
I'm repairing the power supply of a Magnavox TV (37MF337B/37). It blew the tops of four CapXon GF-series capacitors.
I would like to use some caps with higher voltage ratings and longer lifetime ratings than the bad ones I'm replacing.
If I do that though, they won't fit unless I leave them above the surface of the board: I won't be able to pull the leads through the holes so as to leave the bottoms of the caps snug against the board.
Would that be likely to cause any electrical problems?
The CapXon specs are as follows:
13mm x 25mm, 5mm lead spacing, 1000uF, 35V, 20%, 105 degC, ripple: 2780 mA @105degC and 150 MHz, impedance@20degC: 0.019 Ohms, 5000 hrs. lifetime.
I would like to replace that with a 50V Panasonic part EEU-FR1H102:
16mm x 25mm, 7.5 mm lead spacing, 1000 uF, 50V, 20%, ripple: 3320 mA@105degC and 150 MHz, impedance@20degC: 0.019 Ohms, 10,000 hrs. lifetime.
Since the lead spacing and the diameters are different, the new caps couldn't rest directly on the board. The leads would need to be say 5/8" long between the board and the bottoms of the new caps.
Would this different way of mounting the new caps be worth the improved specs of the larger parts?
Or would it cause problems, for example shortening the lives of these or other parts?
