□ INTRODUCTION
MMO For Metal Oxide Resistor to show long-term stability under high temperature, the unit area of
resistance film must withstand larger loads, The small-sized high-performance metal oxide film
Resistor are made of high-quality ceramic core with size greatly reduced in comparison with RS,
while having the same performance of large-sized Resistor.
(MMO 對於電阻長期穩定的高溫下,電阻薄膜的面積必須承受更大的負荷,小型高性能金屬氧化物
薄膜電阻器是由高品質陶瓷棒大大降低了與RS的比較,而具它有相同大型電阻相同的性能。)
