Mainjiniya anzanu, kodi mudakumanapo ndi vuto la "phantom" lamtunduwu? Chipata chosungira deta chopangidwa bwino chinayesedwa bwino mu labu, koma patatha chaka chimodzi kapena ziwiri zogwiritsidwa ntchito kwambiri komanso kugwira ntchito m'munda, magulu enaake anayamba kukumana ndi kutayika kwa mapaketi kosamvetsetseka, kuzimitsidwa kwa magetsi, komanso kuyambiranso. Gulu la mapulogalamu linafufuza bwino codeyo, ndipo gulu la zida linayang'ananso mobwerezabwereza, pamapeto pake pogwiritsa ntchito zida zolondola kuti adziwe chomwe chikuyambitsa: phokoso lamphamvu kwambiri pa njanji yamagetsi yapakati.
Yankho la YMIN Multilayer Capacitor
- Kusanthula Kwaukadaulo kwa Muzu wa Chifukwa – Tiyeni tifufuze mozama za "kusanthula kwa matenda." Kugwiritsa ntchito mphamvu kwa ma chips a CPU/FPGA m'ma gateways amakono kumasintha kwambiri, ndikupanga ma harmonics ambiri amagetsi amphamvu. Izi zimafuna kuti ma network awo ochepetsa mphamvu, makamaka ma capacitor akuluakulu, akhale ndi mphamvu yotsika kwambiri yofanana (ESR) komanso mphamvu yamagetsi amphamvu. Njira yolephera: Pansi pa kupsinjika kwa nthawi yayitali kwa kutentha kwakukulu ndi mphamvu yamagetsi amphamvu, mawonekedwe a electrolyte-electrode a ma capacitor wamba a polymer amawonongeka nthawi zonse, zomwe zimapangitsa kuti ESR iwonjezeke kwambiri pakapita nthawi. Kuwonjezeka kwa ESR kuli ndi zotsatira ziwiri zofunika: Kuchepetsa mphamvu yosefera: Malinga ndi Z = ESR + 1/ωC, pama frequency apamwamba, impedance Z imatsimikiziridwa makamaka ndi ESR. Pamene ESR ikuwonjezeka, mphamvu ya capacitor yoletsa phokoso lamagetsi amphamvu imachepa kwambiri. Kuwonjezeka kwa kutentha: Ripple current imapanga kutentha kudutsa ESR (P = I²_rms * ESR). Kukwera kwa kutentha kumeneku kumathandizira kukalamba, ndikupanga kuzungulira kwa mayankho abwino komwe pamapeto pake kumabweretsa kulephera kwa capacitor msanga. Zotsatira zake: Capacitor array yolephera singathe kupereka chaji yokwanira panthawi yosintha kwa katundu, komanso singathe kusefa phokoso la ma frequency apamwamba lomwe limapangidwa ndi magetsi osinthira. Izi zimayambitsa glitches ndi kuchepa kwa magetsi operekera chip, zomwe zimapangitsa kuti pakhale zolakwika za logic.
- Mayankho a YMIN ndi Ubwino wa Njira – Ma capacitor a YMIN a MPS a multilayer solid-state capacitors apangidwa kuti agwiritsidwe ntchito molimbika.
Kupambana kwa kapangidwe kake: Njira ya multilayer imaphatikiza ma chips angapo ang'onoang'ono a solid-state capacitor pamodzi mkati mwa phukusi limodzi. Kapangidwe kameneka kamapanga mphamvu yofanana ya impedance poyerekeza ndi capacitor imodzi yayikulu, zomwe zimachepetsa ESR ndi ESL (inductance yofanana) kukhala yotsika kwambiri. Mwachitsanzo, capacitor ya MPS 470μF/2.5V ili ndi ESR yotsika mpaka 3mΩ.
Chitsimikizo cha Zinthu: Dongosolo la polima lolimba. Pogwiritsa ntchito polima yolimba yoyendetsa, imachotsa chiopsezo cha kutuluka kwa madzi ndipo imapereka mawonekedwe abwino kwambiri a kutentha. ESR yake imasiyana pang'ono pa kutentha kwakukulu (-55°C mpaka +105°C), makamaka kuthana ndi zoletsa za moyo wa ma capacitor a electrolyte amadzimadzi/gel.
Kagwiridwe ka ntchito: ESR yotsika kwambiri imatanthauza kuthekera kwakukulu kogwiritsira ntchito mphamvu ya ripple current, imachepetsa kukwera kwa kutentha kwamkati, komanso imakonza MTBF ya dongosolo (nthawi yapakati pakati pa kulephera). Yankho labwino kwambiri la ma frequency apamwamba limasefa bwino phokoso losinthira la MHz, ndikupatsa chip mphamvu yoyera.
Tinayesa mayeso ofanana pa bolodi la amayi lomwe linali ndi vuto la kasitomala:
Kuyerekeza kwa mawonekedwe a mafunde: Pansi pa katundu womwewo, kuchuluka kwa phokoso la njanji yamagetsi yoyambirira mpaka pachimake kunafika pa 240mV. Pambuyo posintha ma capacitor a YMIN MPS, phokosolo linachepetsedwa kufika pa 60mV. Mafunde a oscilloscope akuwonetsa momveka bwino kuti mawonekedwe a mafunde amagetsi akhala osalala komanso okhazikika.
Kuyesa kukwera kwa kutentha: Pansi pa mphamvu yonse ya ripple current (pafupifupi 3A), kutentha kwa pamwamba pa ma capacitor wamba kumatha kufika pa 95°C, pomwe kutentha kwa pamwamba pa ma capacitor a YMIN MPS kuli pafupifupi 70°C yokha, kutsika kwa kutentha kwa kupitirira 25°C. Kuyesa kwa moyo wofulumira: Pa kutentha kovomerezeka kwa 105°C ndi ripple current yovomerezeka, pambuyo pa maola 2000, kuchuluka kwa mphamvu yosungira mphamvu kunafika >95%, kupitirira kwambiri muyezo wamakampani.
- Zochitika Zogwiritsira Ntchito ndi Ma Model Ovomerezeka - YMIN MPS Series 470μF 2.5V (Miyeso: 7.3*4.3*1.9mm). ESR yawo yotsika kwambiri (<3mΩ), kuchuluka kwa mphamvu ya ripple current, komanso kutentha kwakukulu (105°C) zimawapangitsa kukhala maziko odalirika a mapangidwe amagetsi apakati pazida zolumikizirana zama netiweki zapamwamba, ma seva, makina osungira, ndi ma motherboard owongolera mafakitale.
Mapeto
Kwa opanga zida zamagetsi omwe akuyesetsa kukhala odalirika kwambiri, kugawa magetsi sikungokhudza kusankha mphamvu yoyenera; kumafuna chisamaliro chachikulu pa magawo osinthika monga ESR ya capacitor, ripple current, ndi kukhazikika kwa nthawi yayitali. Ma capacitor a YMIN MPS ambiri, kudzera muukadaulo watsopano wa kapangidwe kake ndi zinthu, amapatsa mainjiniya chida champhamvu chothana ndi zovuta za phokoso lamagetsi. Tikukhulupirira kuti kusanthula kwaukadaulo kwakuya kumeneku kukupatsani chidziwitso. Kuti mudziwe zovuta zogwiritsira ntchito ma capacitor, pitani ku YMIN.
