The MM and SMM MELF resistor series offer significant advantages compared to thin film chip resistors. The cylindrical ceramic substrate is covered by a high-quality homogeneous metal film resistive layer. Its cylindrical shape results in a larger substrate volume and resistive element area as compared to chip resistors, allowing for a higher power dissipation. The helical laser trimming cut applied to the resistive film allows the resistor to evenly distribute thermal energy across the entire resistive element when it’s in use. As a result, the MELF resistors stability is enhanced and its pulse load capability increased.
