    Hello,

    (This is my first post so be gentle with me)
    I'm trying to repair a treadmill ( incline motor once started wound all the way out) on inspection and one of the components one of components of the circuit board was broken(snapped). I originally thought this was an array resistor.

    I have measured the resistance between the pins as follows
    Pin 1 to pin 2 is 40kΩ
    Pin 1 to pin 3 is 50kΩ
    Pin 1 to pin 4 is 60kΩ
    1-5 is 70kΩ
    1-6 is 80kΩ
    1-7 is 90kΩ
    1-8 is 100kΩ
    2-3 is 50kΩ
    2-4 is 60kΩ
    Etc.
    9 and 10 are broken off.

    Markings on it are
    T103/103G
    Please let me know what this is (a ladder network?) and how I could find/specify a replacement. To fix this circuit board

    Thank-you very much

    Thank-you for such a quick response. this is a close-up photo on the board. Looking at the datasheet for the link you posted it looks like it's a 121 10k? Is this right? Or could I put in a R2R backwards?
