Resistor 小型化金屬氧化膜電阻

PDF File  Data Spec Metal Oxide Film Resistor - MOS Series

Resistor INTRODUCTION
These Metal Oxide Resistors offer excellent performance in applications where stability and uniformity of
characteristics are desired. They provide lower cost alternatives to Carbon Composition Resistors and
General Purpose Metal Films.  Metal Oxide also can replace many low power General Purpose Wire wound
applications, saving both money and time, with shorter delivery cycles.

功率因素調整二極體之應用介紹

功率因素調整(PFC)Power Factor Correction,用來表示電子産品對於電力的利用效率,是指有效功率除與總耗電量的比值,其原理主要是調整交流電輸入電流之波形,盡可能與直流電電壓波形盡可能一致,其計算出來的功率因素值越高(趨近於1),代表其電源利用率越大,電能轉換效率也越好。 一般電子設備沒有功率因素校正(Power Factor Correction, PFC)時其PF值約只有0.5

目前市面上有PFC的電源產品有兩種,一種為被動式(Passive)PFC,另外一種為主動式(Active)PFC.其中主動式PFC提高電力轉換效率,降低設備所傳導之電流損耗,比被動式更高效率,降低視在功率,讓電力的消耗更少,響應環保。電子3C產品逐漸多採用主動式PFC的元件設計使產品更輕薄短小高效率以符合市場趨勢
