  • TPL0501-100: TPL0501-100 Rheostat range limitation

    Resolved
    Part Number: TPL0501-100 The data sheet for TPL0501-100 states that the nominal resistance between terminal H and terminal L is 10 kOhm in Rheostat Mode (pg. 9). Is the nominal resistance limited to 10 kOhm or should this be 100 kOhm (Rtot)?
