This part is a 1210-size surface-mount chip resistor with ±1% tolerance, compliant with the Restriction of Hazardous Substances (RoHS) Directive. It has a resistance of 2.4ohms, and it is manufactured by Uniroyal. The 1210W2F4020T5E designation describes this component's size, resistance, tolerance and construction. The first three characters (1210) indicate the size of the part, which in this case is 1210, a metric components designation which means 3.2mm x 1.6mm. The 'W' indicates the construction of the resistor, which is a thin metal layer over an insulating layer, with a conductive layer and a protective coating. The 2F4 indicates the nominal resistance in Ohms, which is 2.4 Ohms with a suffix of ‘0’ (2.40 Ohms). The 020 represents the tolerance code, or the percentage of this nominal resistance that the actual resistance falls within. In this case it is 1% (±0.024ohms). The T5 represents the manufacturer’s part series and is used to distinguish between resistors with the same size, tolerance and resistance. The ‘E’ indicates the product is RoHS compliant.
