Q: Zan iya tuƙa wannan nunin tare da fil ɗin microcontroller 5V kai tsaye?

A: A'a. Dole ne ka yi amfani da resistor mai iyakance halin yanzu ko, zai fi dacewa, keɓantaccen IC mai tuƙi na halin yanzu akai-akai. Haɗa fil ɗin 5V kai tsaye zuwa cathode na sashe (tare da anode mai wutar lantarki) zai yiwu ya wuce matsakaicin halin yanzu na ci gaba (25mA) kuma ya lalata LED. Dole ne a ƙididdige ƙimar resistor bisa ga ƙarfin wutar lantarki, VF na LED, da halin yanzu na gaba da ake so (IF).

Q: Me yake nufi da \"derating linear daga 25°C\" don halin yanzu na gaba na ci gaba?

A> Yana nufin cewa ga kowane digiri na Celsius da yanayin yanayi ya tashi sama da 25°C, matsakaicin halin yanzu na ci gaba da aka yarda yana raguwa da 0.28 mA. Misali, a 50°C (25°C sama), matsakaicin halin yanzu zai zama 25 mA - (25 * 0.28 mA) = 25 mA - 7 mA = 18 mA kowane sashe.
