Re: Measuring Resistance of Metal Oxide Power Resistor

Managed to get the white gunk off. It's a K6A60D. My measurements were across the pins with it still in the board so it's possible I'm not actually measuring the mosfet but something else in the circuit.

Re: Measuring Resistance of Metal Oxide Power Resistor

I measured across the mosfet and got 2.111 KOhms Gate-Drain & Source-Drain. I got 1.8 Ohms Gate-Source. I'm not very experienced with this kind of thing so not sure if that is helpful without knowing the actual specs of this particular mosfet.

Re: Measuring Resistance of Metal Oxide Power Resistor



Thanks for confirming this Pete.

I'll look into the other parts that yourself and R_J mentioned....

I've seen resistor datasheets showing some resistors with a PT of 52mm and others with a PT of 64mm. What is this dimension?

Do you think it's the part I circled that's most likely to have taken out the resistor?...

Re: Measuring Resistance of Metal Oxide Power Resistor



Thanks...What is an FR resistor?

Also...should I be able to test normally, just stick my meter on resistance and go across the legs?...

Can I measure a Metal Oxide Power Resistor the normal way?

When I put my fluke on resistance and measure across the legs (I've removed it) I get 22 kOhms. Reading the bands I'm expecting this to be a 330 mOhm +/- 5% resistor.

Am I reading it wrong or is it stuffed?...

Re: Netgear Prosafe JGS516 switch with Delta Electronics ADP-40VP PSU board (fixed)

Not so lucky for me so far. My Netgear GS716T died last night and it has a Delta ADP-40VP power supply in it the same as the others on here. Found this forum thread and promptly popped out the 47uf cap and replaced it and no difference...still dead. Pulled out the 400V 100uf filter cap and it's got 90uf...bought a new one...new one is 97uf so not sure if that's the issue. Kept tracing and noticed the big resistor at the filter cap legs (Orange, Orange, Silver, Gold) My resistor chart says 0.33 Ohms...
