Isihlungi Sokunikezwa Kwamandla Esinconyiwe
Qaphela:
Ama-inductor anokumelana kwe-DC okungaphansi kwe-1Ω kufanele asetshenziswe ukuze kugcinwe i-voltage edingekayo ku-pin yokufaka ye-SFP ene-voltage yokuphakelwa engu-3.3V. Uma kusetshenziswa inethiwekhi yokuhlunga yokuphakelwa enconywayo, ukuxhuma okushisayo kwemojuli ye-transceiver ye-SFP kuzoholela ekungeneni kwamandla kagesi okungaphezu kwama-30 mA okukhulu kunenani lesimo esizinzile.
