This electronic part, the RM10JTN390 with Chip Resistor - Surface Mount 39Ohms ±5% 1/8W 0805 RoHS, is a specialized component of the TA-I Tech lineup for use in circuit designs or other electronic applications. It is a resistor, meaning it can provide a resistance in an electrical circuit, allowing electrical current to follow a predetermined path. This resistor is a surface mount component, meaning it is made to be connected to an external circuit on a surface, such as a printed circuit board. It has a resistance of 39 Ohms with a tolerance of 5%, meaning it will provide around 37-41 Ohms of resistance. Also, it has a power rating of 1/8W, which means it can handle up to 1/8 Watts of power before becoming damaged. Furthermore, this resistor is RoHS compliant, meaning that it is approved for use in countries that abide by the Restriction of Hazardous Substances (RoHS) directive.
