◆ MF18 (18W) Resistance : 0.05R ~ 1M Tolerance: ±1%, ±5%.

◆ MF20 (20W) Resistance : 0.05R ~ 1M Tolerance: ±1%,± 5%.

◆ MF30 (30W) Resistance : 0.5R ~ 1M Tolerance:± 1%, ±5%.

◆ MF50 (50W) Resistance : 0.2R ~ 1M Tolerance: ±1%, ±5%.

特點:

TO-220 MF 系列封裝, 不使用金屬法藍底板,而是直接進行模壓包封,使得陶瓷基板的有效面積(及相應電阻模層的有效面積)增大,從而使得電阻具有較強的脈衝電負荷性能。MF 系列採取了陶瓷基片直接裸露的結構,並配合使用專用L型錳鋼散熱片,改善其散熱性能,當在電阻本體溫度升高時能保持它有較佳的額定功率及有極佳的脈衝電負荷性能。

TO-220 MF 系列封裝, 使用M3螺絲安裝,配合專用彈簧片,克服模壓電阻本體機械強度不够的弱點,使固定螺絲壓力直接作用於電阻本體的中心,增強了電阻的熱傳導性。無電感制成。

Mayloon Products Power Resistor ML series resistors satisfy demanding applications for accurate and stable power resistors housed in the convenient TO-220 case. The resistance element is Isolated from the mounting tab by an alumina ceramic layer, providing very low ther- mal resistance and ensuring high insulation resistance between terminals and tab.

The non-inductive design makes these products especially useful in high frequency and high speed pulse applications.
