Pulse Load High Voltage MELF Resister

The pulse load high-voltage MELF resistor features a rated power range of 0.4W to 1W and a resistance span from 300K ohms to 39M ohms, with tolerances of ±1%, ±2%, and ±5%. Thanks to its MELF package of 0204/0207, it boasts an SMD-compatible structure. Its proprietary thin film can handle much higher operating voltages than general-purpose resistors, as it incorporates surge protection functionality coated onto a cylindrical ceramic rod and encapsulated as a MELF resistor. The pulse load high-voltage MELF resistor offers superior heat dissipation compared to chip resistors.
