AVX nkesa data: AVX tantalum capacitor Anode nhọrọ
Ịmafe ike esenyịn, a nkịtị na-emekarị nke microprocessor na digital circuit a na-eji belata mkpọtụ nke elu ugboro na-arụ ọrụ. Iji na-eme nke a, mmiri ga-enwe ala ESR (resistivity), elu capacitance na elu pụrụ ịdabere.
AVX tantalum capacitor An anode maka n'ozuzu n'elu ebe, karịsịa n'elu ebe na olu ruru, bụ otu n'ime ndị isi kwa ikpebi ESR uru, n'elu ebe bụ nnukwu, ibu uru nke ESR. The ojiji nke multi anode na-ukwuu belata otu ụzọ AVX tantalum capacitor ESR uru, ya omume bụ na-eji otu electrode ihe a capacitor ahu.
The omenala obibia
Na ngwa nke ogologo ndụ na elu pụrụ ịdabere, ot MnO2 electrode efere AVX tantalum capacitor Nke ka a na-ewu ewu nhọrọ. The manganese dioxide technology nwere ike inye ndị magburu onwe ubi arụmọrụ ma kwụsie ike na gburugburu ebe obibi na na a dịgasị iche iche nke voltages dị ka 2.5 ~ 50V na elu resistivity na thermal eguzogide ọnụego, ngwaọrụ imewe ọrụ okpomọkụ na 125 DEG C. Otú ọ dị, jiri ya tụnyere ihe AVX polima tantalum capacitors, elu manganese dioxide electrode usoro ESR bụ a mwepu.

(2) tụnyere otu anode unit olu, multi anode capacitor na ala arụmọrụ, nke na-eduga a amụma na-apụghị-enweta na a otu multi anode anode ka CV (mgbe nile voltaji akpata. N'eziokwu, mkpa anode iji nweta ọzọ mfe , na ndị ọzọ na-adị mfe banye n'ime abụọ manganese dioxide electrode usoro, na elu CV nwere ike ji mee, ya mere, multi anode capacitor nwere ike nweta otu ma ọ bụ ọbụna ọkwa dị elu nke CV.
Common anode ụdị
On ahịa taa ejikarị multi anode tantalum emekarị adopts na vetikal ndokwa maka 3 ~ 5 anode na a capacitor ahụ, dị ka e gosiri na ọgụgụ 1. Nke a bụ n'ezie si a n'ichepụta echiche, ma ọ bụrụ na si n'ọnọdụ nke ESR, a ngwọta ọ bụghị dị ka ihe ọma dị ka ndị kwụ okirikiri nhọrọ ukwuu, anode efere thinner na a kwụ layout n'ihu belata ESR.

Chepụta 1 Multi anode ngwaọrụ eji anode abụọ ma ọ bụ karịa abụọ na a capacitor ahụ

Multi anode ngwaọrụ ọhụrụ multi anode imewe na-eri na ọnụ ọgụgụ na-amụba exponentially anode. Ugbu a, ọtụtụ ojiji na imewe nke ezigbo imewe nke atọ anode kemgbe nso ndị na-eri na ruru nke ESR.
The longitudinal Ọdịdị imewe, ihe anode electrode site silver epoxy resin mama na jikọọ na abụọ, na mgbe ahụ ka ndị ọzọ electrode ụzọ etiti. A otu anode capacitance otu ụzọ e ji mee ihe na ọkọlọtọ, otú ahụ n'ichepụta technology na agadi yiri, na-enweghị nkà na ụzụ ọhụrụ njikọ kwukwara ọtụtụ ndị ọzọ ego anode imewe.
N'aka nke ọzọ,, kwụ imewe mkpa ọhụrụ ngwọta maka njikọ n'etiti anode, nke na-eduga ná mgbanwe nke oké ọnụ technology. Ya mere, nnọọ, a haziri ka e ji mee ihe maka otu ogbe multi anode capacitor ndụ mmepụta. The kwụ imewe na ndị ọzọ na-eji na ụfọdụ pụrụ iche ngwa, bụ site ịgbado ọkụ ma ọ bụ jigging usoro, abụọ ma ọ bụ karịa abụọ zuru ezu capacitor na-agbakwunyere na n'usoro ma ọ bụ modul.
The iche n'etiti arụmọrụ nke ESR kwụ na vetikal Ọdịdị dị ka e gosiri na ọgụgụ 2. Ihe atụ a bụ ngụkọta oge nke ndị D ụdị capacitor dabeere na ozizi Ọgụgụ 2 na-egosi na abụọ kwụ Ọdịdị na vetikal Ọdịdị nke anode Mmaji anode usoro ESR uru bụ yiri. Otú ọ dị, ikwu price uru na ESR kwụ Ọdịdị bụ ihe doro anya.
