人：美商Vishay & 台灣奇力新
事：電感廠傳出美商Vishay握有的Molding專利將於2017年到期解禁
時：2015/9/30
地：美國及台灣
物：奇力新為全方位電感廠，旗下產品包含薄膜電感、一體成型電感（Molding）、繞線式電感以及Multi
Layer製程，去年四大產品線同步擴產，其中以應用於智慧型手機的產品最引關注
摘要：
奇力新於2013年與美商Vishay簽訂全球性的授權協議，奇力新與其關係企業可在Vishay授權之下，製造、使用、出售一體成型高功率扼流器或是電感。
專利雖然解禁，但因Molding製程牽涉到粉末配方，目前僅德、日兩地有能力提供，但少數的貨源又被奇力新、乾坤二大廠把持住，奇力新還有自己的粉末廠，專利解禁之後理論上大家都可以生產，然而如何調配出符合特性的配方才是Know-How，專利解禁之後，不會改變目前的競合態勢。

ABSTRACT
A high current, low profile inductor includes a wire coil having an inter coil end and an outer coil end. A magnetic material completely surrounds the wire coil to form an inductor body. First and second leads connected to the inner coil end and the outer coil end respectively extend through the magnetic material to the exterior of the inductor body. The method of operation involves pressure molding the magnetic material around the wire coil.

ABSTRACT
A high current, low profile inductor includes a conductor coil surrounded by magnetic material to form an inductor body. The inductor coil is formed from a flat plate which is cut into a sine-shaped configuration and then is folded in accordion fashion to create a helical coil.
