Composite Film Type Ceramic Composition MELF Resistor

The Ceramic Composition Metal Electrode Leadless Face (MELF) Resistor boasts impressive electrical and physical characteristics. With a power rating of up to 1 Watt and a wide resistance range from 33 Ohms to 22K Ohms, it caters to the needs of various circuit designs. The ceramic rod of this resistor demonstrates exceptional anti-pulse capabilities within a tolerance range of ±5% to ±20%, ensuring stable operation in complex and varied electrical environments. Furthermore, thanks to the Surface Mounted Device (SMD) structure enabled by the MELF package, the resistor possesses a more robust mechanical structure that can effectively withstand adverse working conditions such as vibration and thermal shock, thereby extending its service life and enhancing the reliability of the system.
