Yini inhloso yama-capacitors amaningi ku-chip'sUkunikezwa kwamandla kagesiIzikhonkwane?
Njengonjiniyela be-Electronics Kuyaziwa ukuthi ama-capacitors ngokuvamile akhonza imisebenzi emine eyinhloko: Ukuqunjelwa, ukuhlanganisa (ukuvimba i-DC ngenkathi kuvumela i-AC ukuthi kudlule), ukuhlunga, kanye nokugcinwa kwamandla. Namuhla, ngizogxila ekuchazeni umsebenzi wokukhohlisa.
Izinhlobo ezijwayelekile zama-capacitors asondayo
Lesi sithombe esingenhla sibonisa i-schematic enengxenye yokulungiswa kwamandla okuhambisa amandla kwe-microcontroller's application. Le MCU idinga ujantshi wamandla amahlanu we-3.3v, okuvame ukunikezwa yi-LDO (umlawuli ophansi ophansi), njenge-LM1117.
Kungani ama-capacitors aqalayo ayadingeka
Ngenkathi i-LDOS ngokuvamile ihlinzeka ngama-voltages aqinile aqhathaniswa nawoAbaguquli be-DC-DC(isib. Ukuze sibhekane nalokhu, sibeka ama-capacitors asondelana eduze kwezikhonkwane zamandla e-chip. Lawa ma-capacitors athatha umsindo ophakeme we-ac acrency esuka ekuhlinzekeni kwamandla, akwehlise phansi, ngaleyo ndlela aqinisekise ukuthi i-chip ithola i-voltage ezinzile nethembekile ye-DC. Ukusebenza kahle, ama-capacito aqothulayo kufanele abekwe eduze ngangokunokwenzeka ezinhlakeni ze-chip.
Kungani kusetshenziswa i-capacitor engu-0.1μf evame ukusetshenziswa?
Lapho sifunda ubuqotho bamandla, sivame ukuhlaziya i-capacitor efana nale ndlela, kumafrikhwensi aphansi, i-capacitor ngokuyinhloko isebenza njengesihlungi. Kodwa-ke, njengoba imvamisa inyuka, isakhi esingelona iqiniso seCapacitor siba balulekile futhi ekugcineni sibusa. Ngaphandle komkhawulo okhethekile wokuvama, ukusebenza kahle kweCapacitor kuncipha. Lokhu kusho ukuthi atimvamisa ephezulu, i-capacitor ayisaziphathi njenge-capacitor "emsulwa". Izici zangempela zokuhlunga ze-capacitor ziboniswa kwijika elingezansi:
Kusuka ku-curve, ukuhlunga okuhle kwenzeka endaweni ephansi kakhulu yeumlingaijika (ubuncane bokuphazamiseka). Kodwa-ke, njengoba imvamisa inyuka, i-capacitor engu-0.1μ Ngokuvamile okuphezulu, amanani amancane amakhono (isib. 0.001μF) ayadingeka ekuhlunga kahle.
Isixazululo: Ama-capacitors ahambisanayo
Ukubhekana nalokhu kukhawulelwa, imiklamo eminingi yesifunda isebenzisa ama-capacitors amaningi ngokufana namanani ahlukile we-capcacitance. Ngokuhlanganisa ama-capacitors amanani ahlukahlukene, ukuhlupheka okusebenzayo kokuhlunga kwandiswa, kuqinisekisa ukucindezelwa komsindo okungcono ngaphesheya kwe-spectrum ebanzi. Le ndlela ivumela ukusebenza kokuhlunga okuthuthukisiwe ngaphezulu kobubanzi obubanzi bezakhiwo.
