Q:6. Kedu ụdị mgbanwe ESR nke YMIN siri ike-mmiri ngwakọ capacitors mgbe reflow soldering? Kedu otu esi ejikwa mkpụgharị?
A: A tụrụ atụ ESR mgbanwe nke YMIN capacitors bụ ≤0.002Ω (dịka, 0.0078Ω → 0.009Ω). Nke a bụ n'ihi na nhazi ngwakọ mmiri siri ike na-egbochi ire ere nke electrolyte dị elu, yana usoro nchikota jikọtara ọnụ na-eme ka kọntaktị electrode kwụsie ike.
Q:7. Kedu otu esi ahọrọ capacitors iji wedata oriri ike na sekit ntinye nzacha OBC?
A: YMIN ụdị ESR dị ala (dịka, VHU_35V_270μF, ESR ≤8mΩ) ka a na-ahọrọ iji belata mfu ntinye-ọkwa. N'otu oge ahụ, ntapu nke ugbu a kwesịrị ịbụ ≤20μA iji zere ịba ụba ike oriri njikere.
Q:8. Kedu uru ndị YMIN capacitors nwere njupụta capacitance dị elu (dịka, VHT_25V_470μF) na usoro mmepụta voltaji nke DCDC?
A: High capacitance ebelata mmepụta ripple voltaji na lowered mkpa ụdi nzacha. Nhazi kọmpat (10 × 10.5mm) na-ebelata akara PCB ma belata mfu ndị ọzọ nke inductance parasitic kpatara.
Ajụjụ: 9. YMIN capacitor parameters ga-adagharị ma na-emetụta ike oriri n'okpuru ọnọdụ ịma jijiji-ọkwa ụgbọala?
A: YMIN capacitors na-eji nkwado nhazi (dị ka imewe electrode na-agbanwe agbanwe) iji guzogide ịma jijiji. Nnwale na-egosi na mgbanwe mgbanwe ESR na ntapu ugbu a mgbe ịma jijiji erughị 1%, na-egbochi mmebi arụmọrụ n'ihi nrụgide ọrụ.
Q: 10. Gịnị bụ okirikiri nhọrọ ukwuu chọrọ maka YMIN capacitors n'oge a 260 ° C reflow soldering usoro?
A: A na-atụ aro ka capacitors nọ ≥5mm pụọ na ihe ndị na-emepụta okpomọkụ (dị ka MOSFET) iji zere ikpo ọkụ mpaghara. A na-eji imewe ihe na-ere ihe na-ekpo ọkụ na-ekpo ọkụ iji belata nrụgide gradient thermal n'oge ịrịgo.
Q: 11. YMIN siri ike-mmiri ngwakọ capacitors dị oke ọnụ karịa omenala electrolytic capacitors?
A: YMIN capacitors na-enye ogologo ndụ ogologo oge (135 ° C / 4000h) na obere ike oriri (na-echekwa ụgwọ usoro jụrụ oyi), na-ebelata ụgwọ ọrụ ndụ ngwaọrụ site na 10%.
Q:12. YMIN nwere ike ịnye parampat ahaziri ahazi (dị ka obere ESR)?
A: Ee. Anyị nwere ike ịhazigharị usoro electrode dabere na mgbanwe mgbanwe nke ndị ahịa (dịka ọmụmaatụ, 100kHz-500kHz) iji belata ESR ruo 5mΩ, na-ezute ihe achọrọ OBC dị oke elu.
