sir tony ano ba ang mas preferred gamitin? mica or silicon pad? ano pagkakaiba nila...

karamihan nang insulator dito sa akin puro para sa sanken 2922/1216.. pwede kaya to gupitin para magamit sa to-264..

MT-200 pala yan....pwede ka ring gumamit ng kapton tape.....yung mica, universal yan, yung silicon pad hindi kailangan lagyan ng silicon grease....merong seller dito ng kapton tape, pwede mo pang i-cut to size...

kapton tape yan ba yung parang cellophane na yellow orange ang color?..

pag yan ang ginamit kailangan pa ba nang thermal paste?


sensya na mga sis matanong ako...

may nakapag-post dati dito na merong kapton tape sa Deeco na baka mali ang presyo. nakalimutan ko na kung sino nag-post dati noon.

meron ding mga nagbebenta sa sulit nung medyo malalaking silicon pads (para talaga sa mga processor ng laptop) na pwedeng kumasya sa ibang transistor. ang inherent advantage ng silicon is 'yung heat transfer at mas madali siyang mag-conform doon sa shape nung kakabitan. isa niya pang advantage, though 'di masyadong pronounced on linear applications, is mas mababa ang magiging parasitic capacitance niya doon sa heatsink dahil magiging mas makapal siya kaysa sa comparable mica sheet.

yes pwedeng pwede yang mica insulator, lagyan mo lang ng silicon grease.
yan yung tinutukoy kong TB-35(sanken> 2sc2922/2sa1216)

salamat master sa idea... galing naman..

mga sis baka may mga extra kayong Mica insulator jan na di na nagamit TO-3PL baka pwedeng benta nyo na lang sa akin...

wahuhuhu bakit ngayon ko lang nabasa ito...

sir nakabili ako nang insulator pero silicone pad hindi mica or glas typpe pwede rin kaya to sa MJL4202A at MJL4281A na transistor na gagamitin ko..
