    How to find out the rating of my blown thermister

    Hi folks i've got a blown thermister but all it says is NTC 201 on the board and 054 on the green thermister.
    Its from a mirage PI-190DTLB inverter power board from my zerox 22" lcd monitor which im currently fixing.

    Probably an SCK-054

    SCK-054
    5Ω - cold ( 25°C )
    4A - continuous current
    180mΩ - at max current

    12mm diameter disc.

    It is a thermistor, but it's actually called an Inrush Current Limiter.

        would it be possible to use a
        NTC 5D-09 instead of a NTC 5D-11
        sck-....................... , SCK-054
        5Ω - cold ( 25°C )......, 5Ω - cold ( 25°C )
        3A - continuous current. 4A -continuous current
        210mΩ - at max current.180mΩ - at max current

          No the continuous rated current is less.

          That's like putting a 1/2 watt resistor where a 1 watt resistor was. It will just burn up.

          Elements of the past and the future combining to make something not quite as good as either.

            Dell 2209WA - power supply - Fusible Resistor replacement
            by jinu_j
            Hi

            I am trying to repair an ancient Dell 2209WA Monitor which suddenly shut off with a pop sound. On investigation found that one of the fusible resistors had blown. Further investigation identified multiple components as faulty because of which the fusible resistor blew. Please refer the attached circuit diagram showing the components that were found to be damaged.

            1. FR950 - blown fusible resistor - 0.2 Ohm 1W
            2. Q950 - shorted Q950 MOSFET - 650V 10A N Channel Mosfet
            3. R835 - Blown Resistor - 20KOhm SMD resistor

            Is it no harm to replace with capacitor without ripple current rating?
            by chth96
            When I tried to repair LG 29 inch CRT TV, I found that the ESR value of samyoung SMS capacitor(160v 2.2uf), which is very close to D1879 transistor, is 6 ohm.


            Judging from above ESR Meter Table,I think It is necessary to replace this sms capacitor.So I visited local electronics shop,and I purchased 160v 2.2uf rubycon YK capacitor.
            But when I browse through rubycon YK datasheet,I found that there is no ripple current rating for 160v 2.2uf specification. But On the contrary, I found 39 mA ripple current rating for 160v 2.2uf SMS capacitor.

            Dell Optiplex GX260 - Advice Needed for Polymodding Motherboard
            by SwedishDiesel
            Howdy folks,

            I have an Optiplex GX260 that blew a couple of those troublesome Nichicon HM series (ultra low ESR) electrolytic capacitors. Because said caps are obsolete, they are pretty much impossible to find on the market; I did find a listing for some but I believe they are counterfeit. I feel the easiest thing to do would be to replace all the blown caps with polymer ones. I am by no means an expert in electronics, and I've found a fair bit of conflicting information, so any guidance or confirmation would be greatly appreciated. While from a practical standpoint it's not worth...

            Where to find a very small fpc connector 0.3mm between 2 pins ?
            by corrize
            Hello, I search this connector (oxydated).
            It's a fpc zif low profile connector. It come from camera sensor, it is very small : 0.3mm between 2 pins.
            I ordered 2 from Aliexpress called « 0.3mm pitch » but one was 0.5mm between 2 pins and the other 0.6mm. In fact « 0.3mm pitch » seams to be the pad width and not the distance between 2 pins.
            I can't find it. The other websites like mouser dont show the datasheet, and I can't check if it is 0.3mm between 2 pins ?


            Do you know how to find this connector please ? What is the exact name for find it ?
