The RN 1/8W 12K F T/B A1 with Metal Film Resistor (TH) Axial,1.7x3.5mm RoHS is a resistor manufactured by Tyohm. It is a 0.125-watt, 12 kilo-ohm (12 kO) resistor with axial lead construction of 1.7 x 3.5 mm in size. Its leads are encased with a metal film instead of carbon, making it resistant to dust and moisture. It is RoHS (Restriction of Hazardous Substances) compliant and is suitable for applications such as a voltage divider, bias resistor, current-limiting resistor, and power distribution circuit. It is widely used in automotive, medical, industrial, and consumer electronics applications.
