Anti-Surge Wire Wound MELF Resistors-Xseries

The X Series of surge-protected wound MELF resistors boasts a rated power of 1 watt, with a wide resistance range spanning from 1 ohm to 150 ohms, and a precise resistance tolerance controlled within ±5%. Specifically engineered to tackle the challenges posed by high surge currents, the X Series finds extensive application in surge protection for power capacitors, current stabilization during motor startups, electric vehicle systems, and renewable energy storage, among other fields. It effectively absorbs and dissipates harmful surge energy, thereby safeguarding circuits from the risks of damage caused by surges.

Thanks to its unique Surface Mount Device (SMD) structure featuring a Metal Electrode Leadless Face (MELF) package, the X Series not only demonstrates superior thermal dissipation performance compared to traditional chip resistors but also possesses a more robust mechanical construction. This design enables the X Series to withstand vibrations and thermal shocks in harsh environments effortlessly, ensuring stable and long-term operation.
