    Opens or closes?

    http://www.mouser.com/Search/Product...wvon6sqw%3d%3d

    I am thinking about buying that to control a fan for the front of my computer. My only question is, does it open the circuit at the specified temp, or close it?

    Mouser says it closes it from the filters and checklist, but the description said it opens at the temp?

      WTF!! Mouser messed up. Mouser says CLOSES, but datasheet says STO-140 "OPENS" means it's normally closed and OPENS within the specified temperature range.

      It will stop conducting at 135-145°F (57-63°C). Mouser page is wrong. 56-64°C is the STC-140. WHOOOOPEEEE! for 1 degree.

      To turn ON a fan you want the STC-140

          and Mouser says the STC-140 Opens!

              Except it is correct in the "Description:" line.

              WHEEEEEE!

              GOOOOOD Medekashin!

                  Here is a link to the Stancor data sheet for disc thermostats.



                  For those who might be interested...
                  Why throw it away? I might need it in the next 40 years. Duh!

                      Drying Oven - Preset Temp Fail
                      by tmcw
                      Here's an unusual one...

                      This is a Gallenkamp oven, used in a laboratory space, goes up to 220 Celcius, but is usually maintained at about 115 Celcius. Used for drying glassware, molecular sieves, and so on. Oven is in excess of 20 years old.

                      It heats up fine, there is an orange light on the front that indicates that the unit is heating, and when it reaches the preset temp, the orange light goes out. All good so far.

                      However, after the preset temp is reached, the temperature continues to rise, power to the heating elements isn't cut off.

                      MSI MAG Z390 Tomahawk BIOS temp, allways at 0ºC and CPU goes protection 800Mhz
                      by foshland
                      Hi to all, my motherboard (bought second hand as faulty, but now working after cleaning the ram slots) have a strange failure that shows 0 Celsius degrees in BIOS, because of that, the CPU goes to protection mode and gets stuck at 800Mhz.

                      Since its a 8-9 Intel generation, I know the CPU temp is the hottest temp of the cores (as i have read in intels documentation) so its not a diode or sensor on the board.

                      External temperature (motherboard temp) is working OK, 27ºC more or less

                      In windows, all the software I have tested shows correct the Core temps

                      concerning gtx675m vram temp
                      by mosfetratus
                      Is 98C vram temp are safe? Less demanding games goes 80ish.

                      Funny thing, there were old non stock thermal pads very botched, so i replaced them. After, temperatures remained the same, but performance (fps) improved significantly. With both thermal pad application GPU core temp was similar.

                      furmark goes about 104C, amperage keeps rising so do temps.

                      Finding comparable ferrite beads on mouser/digikey?
                      by mrkmpn
                      I have an inspiron with "power rail failure" LED codes flashing, and have found a blown capacitor and ferrite bead (inductor, I guess...)

                      I've found the replacement capacitor on mouser, but am unsure how to properly search for the ferrite bead. I have the schematics and boardview, so I have found the original bead part#, but the data sheet doesn't seem to include the information I need for the filters on mouser and digikey.

                      For inductance, and a few other values it just says "Refer to standard electrical characteristics list"

                      Here's...

                      Sony CDP-295/407 tray opens only halfway
                      by Xenon-Codex
                      The mechanism works in other unit, and the working mechanism does the same in this broken unit. So the fault must be in the motherboard. Eject may open the tray with a second try, but it will not close or play any disc.
