Hey, Guys, I'm stumped It

phoenixcomm
phoenixcomm 7 months ago

imageOk, it claims to be a 0.22Ω 3watt power sand resistor, with 3 legs. (so starting at the top and going clockwise, 1 at the top, 2 on the right, and 3 on the left)

My fluke 113 says no it's 0.38Ω between 1 and 2, as well as between 1 and 3, and 0.59/0.60Ω between 2 and 3. 

My HP3435A  set on the 20Ω scale says it's 0.37Ω between 1 and 2, and 0.38Ω between 1 and 3, and 0.59Ω/0.60Ω between 2 and 3.

Something is not right. 

and Please look at the logo, so I can figure out who made the stupid thing..

oh btw the wires go all the way through the body and are about 1" long on the reverse side. 

Thanks again. Cris

    As you've got two meters, perhaps just do your own four-wire measurement. Set a PSU to constant-current, use one of your meters to measure the current through the resistor, the other to measure the voltage…

    Push pull amplifier designs appear to use them. Here is a Sony receiver design using a similar device. https://www.petervis.com/Amplifiers/sony-str-k740p/how-to-fix-sony-amplifier-protect-mode-error…

    Just guessing but: lets assume your leads have about .15 ohm resistance. then its a 0.22 R from 1 to 2, a second 0.22R from 1 to 3 (they both read about 0.37) so from 2 to 3 its 0.44R + the lead reistance…

    Looks similar to the old Pana Sonic

    Matsushita, National and Panasonic all shared the triangular logo at some time.

    Matsushita, National and Panasonic are all the same company, just a different brand for domestic/export/consumer segments.

    Exactly, it also evolved over time.
