Re: NF7-S Rev. 2.0 Bad Capacitor (see pic)

Capacity (1200µ)
Voltage (16v)
Tolerance (+- 20%)
Temperature Range (-40 to +105)

this says nothing really

What kind of specs do you then need to compare to be certain its a match?

Sorry for the late reply on my part, didnt figure out I had a second page in my thread

It leaves out the most important detail: the manufacturer and model

Will write the answer as fast as I find out to inform you guys.

Mfr. Elna
Radial aluminium electrolytic capacitor with straight pins PCB mounting. 105 °C ''Longlife''. Low impedance at high frequencies and a high resistance to ripple current makes it suitable for switching power supplies.
Technical data:
Tolerance: ±20 %
Temperature range: −55 to +105 °C
Leak current: <0.01xCxU +2 μA
Life at 105 °C
øD=5–6.3: 2000 h
øD=8–10: 3000 h
øD=16–18: 5000 h

Capacitance:

Well I've never seen a bad Elna capacitor before, IIRC they're primarily used in audio related applications

44mΩ @ 100Khz isn't too impressive really, especially when you compare it to say a GD series Samxon 1500uF 16v 13mΩ @ 100Khz or the original Rubycon rated at 22mΩ @ 100Khz, however they seem to be not disimilar to Hitano EXR series components ratings
