ESR 0.6Ω capacitance -15% absolute must change?
I have one (of 3) hot swap Supermicro/Ablecom PWS-0050 SP382-TS server PSU that is mal functioning. Supermicro IPMI reports it as bad and led is orange on.
I took it apart tested transistors,...

Re: Inductor or resistor
Thanks. I didn’t know coils have the inductance value color-coded.
Based on lines it’s 1mH.
Can I replace it in this power supply with a coil of 1500uH, 100mA, 25Ω?

Re: Inductor or resistor
And how many ohms does it have?
I can’t decide if first and last colors are red/brown (maybe orange?).

Re: Inductor or resistor
So they are both based on “How to diagnose and fix everything electronics” (attached). But what’s their main purpose: coil or resistor?

Inductor or resistor
See attachment.
This blown component is connected to the output of a bridge rectifier on a SMPS.
It looks like a resistor (it has colored marking lines), but it is marked as L1 on the PCB,...

Re: Desoldering station/gun above ZD-915/474A++ ?
@sam_sam_sam thanks for the extensive review!
I am leaning towards ZD-915, in spite of it being a budget tool, sounds almost fun to maintain and repair it. "Fun" because it will not be heavily...

Re: Desoldering station/gun above ZD-915/474A++ ?
I read that 474A++ gets clogged easily and the tips oxidize quickly. How’s your experience been?
If I had to choose one of those, I’d choose ZD-915. But it has the hard-to-remove-tank problem and...
