ElectThe CQ07W2F2870T5E is a surface mount chip resistor manufactured by Uniroyal Electronics with a rated power of 500mW, resistance of 287O±1%, and a size of 1210 following the ROHS standard. It consists of two separate functional parts, namely, the chip substrate and the terminal. The chip substrate provides structural support to the terminal, absorbing shock and vibration while protecting the terminal from damage. It is also designed to dissipate heat generated by the resistor, ensuring optimal operation. The terminal is made from high quality metals, providing the necessary electrical contacts for connections with the circuit components. It also helps maintain the desired electrical parameters, such as resistance and power rating. The resistor is pre-tested for quality assurance, ensuring it is suitable for use in various applications.
