konti lang ang tindahan dito saamin...
pero try ko pa din mamaya.
Satisfied na ako sa caps na yan... iniwan ko overnight na nakaon... fixed resistors lahat. di naman nadrift.

polysterene capacitor nagtry na akong humanap nyan sa raon with no luck hindi ata nila alam yan  kahit sa eleshop wala meron niyan sa may raon mismo 'yung may mga makalumang log potentiometers. isa-isahin mo lang 'yung mga tindahan, madalas nga lang kokonti lang ang values dahil maliit lang ang demand. karamihan kasi ng pinapalit nila sa ganyan, mylar na lang. |

medyo ok naman ang mylar sis, mas maganda lang 'yung polystyrene. minsan sa budget concerns na nadadaan ang choice, parang 'yung mylar ay middle end na sasakyan na pwede na pero pwedeng may kulang sa ibang aspects, tapos 'yung polystyrene naman ay high end version na maraming additional features. ang typical na reklamo ko lang sa mga locally available na mylar, madaling mabakbak nung kaha kapag natupi-tupi 'yung paa. |

kaya nga... kahit sa ceramic ganun din. kanina nga ikoconsider ko na din na mylar nalang, kaso may oorderin naman talga ako kay miss janet. 2.2uf non-polar (preferably tantalum) - eto di na talga ako makakahanap nito dito sa amin. heheh meron yun sa tweeter... radial at ang laki! (ano bang dielectric nito ). kaya yan, yung polysterene nalang talga. namention ko na din naman ang ceramic, anong difference ng ordinary ceramic at monolithic ceramic capacitors? |

AFAIK, kung hindi electrolytic, polypropylene 'yung ginagamit sa crossover. kapag sa application kasi na mataas na current ang dadaan sa cap, polypropylene ang pinakamaliit ang loss kaya 'di masyado nag-iinit. @sis marce: resulting size lang ang magiging difference sis nung monolithic and multilayer ceramic caps. merong multilayer ceramic caps na abot ng 10uF ang capacitance na mas maliit pa (SMD) sa kinagisnan nating typical .1uF na ceramic. kung ceramic ang gagamitin mo sis dapat 'yung C0G (NP0) ang dielectric para stable sa temperature, ang main advantage nila, hanggang microwave ang useful frequencies nila. |

daming types!!! heheh I really have to review those... @nucleus, i stand corrected! ngayon ko lang narealized na mali ang solution ko... ano bang 2.2uF na non polarized? narealize ko ngayon na polarized nga yung nailagay ko. pero nagwork naman. @Rd, noted yang C0G. Pero parang mas mahihirapan akong hanapin yan ah! at kaya pala malalaki yung non-polarize electrolytic caps na nilalagay sa crossover ay para mahandle yung voltage. may nakita nga ako sa bin ko, 100V ang rating. |

hehehe... nanood kasi ako ng movie kanina, papaantok (bandslam, gwapo pala si vanessa hudgens kung lalaki sya! heheh ). pero biglang may pumasok sa ulo ko... eto at biniverify at tama naman sa actual. heheh |

Nice info sis... heheh... nakagamit na pala ako nyan! tinignan ko yung datasheet ng vishay, hanggang 56nF lang pala yang C0G(NPO). tapos it promises a very good temperature coeficient.// |
