The RTT024024FTH is a surface mount, 4.02M Ohms ±1% 1/16W 0402 RoHS electronic component, manufactured by RALEC. It is a chip resistor, which is a small, passive electronic component that consists of four layers – a conductive layer, a resistive layer, an oxidized layer, and a protective layer. The component is used to provide resistance to an electrical signal, limiting the current that will flow through the circuit and dissipating the energy as heat. It is particularly useful for protecting circuits from voltage spikes and in providing power and ground bypassing. The product is RoHS compliant, which means that it has been tested to meet RoHS standards and has been certified as compliant with all applicable legislation.
