Stable power MELF resistors featuring small tolerance, low temperature coefficient, and high power SMD resistors

Stable power MELF resistors offer a rated power range from 0.4W to 3W and a resistance range from 0.5Ω to 10MΩ. They excel in heat dissipation compared to chip resistors. With robust mechanical structures that resist vibration and thermal shock, they feature low temperature coefficients and tight tolerances. Offering high stability over extended use, they demonstrate excellent power handling capabilities.
