.The AECR2010F0000K9 is a Chip Resistor - Surface Mount 0Ohms ±1% 3/4W 2010 RoHS manufactured by ResistorToday. This resistor is a type of component used to regulate the flow of electric current in electronic circuits. It is made up of a substance that has a known resistance, usually carbon, and two metal plates separated by the substance. The resistor measures just 0 ohms, with a tolerance of ±1%, and a power rating of 3/4 watts. The component is RoHS-compliant, which stands for Restriction of Hazardous Substances, and is a European Commission directive for the promotion of more environmentally friendly electronic components. This resistor comes in the form of a compact surface-mount package, which makes it resistant to vibration, shock, dust, and other environmental contaminations.
