Q: 16. Ni izihe nyungu zo kugereranya za capacitors za VHE ugereranije n'izo mukeba (nka Panasonic na Chemi-con)?
Ubushobozi bwo guhagarara neza bwa ESR:
Ingano y'ubushyuhe bwuzuye (-55°C kugeza 135°C): Ihindagurika rya ≤1.8mΩ (ibicuruzwa bihiganwa birahindagurika >4mΩ).
“Agaciro ka ESR kaguma hagati ya 9 na 11mΩ, karuta VHU kandi ihindagurika rike.”
Agaciro k'Ubwubatsi: Bigabanya igihombo cya sisitemu yo gucunga ubushyuhe ku kigero cya 15%.
Iterambere mu bushobozi bw'umuyoboro wa Ripple:
Igereranya ryapimwe: Ubushobozi bwo gutwara bwa VHE burenze 30% by'abanywanyi bayo ku bunini bumwe, bushyigikira moteri zifite ingufu nyinshi (urugero, ingufu z'amashanyarazi zo kompa amazi zishobora kongerwa kugeza kuri 300W).
Iterambere mu buzima no mu bushyuhe:
Igipimo ngenderwaho cy'ibizamini bya 135°C ugereranije n'icy'umuhatana 125°C → Bingana n'ikirere kimwe cya 125°C:
Igihe cy'ubuzima cya VHE: amasaha 4000
Ubuzima bwo guhatana: amasaha 3000 → inshuro 1.3 z'abanywanyi
Kunoza Imiterere ya Mekanike:
Kunanirwa gusanzwe kw'abanywanyi: Umunaniro wa solder (igipimo cyo kunanirwa >200W mu bihe byo gutigita) FIT)
VHE: “Kongera ubushobozi bwo gusiganwa no guhangana n’ihungabana, bikanatuma umuntu ahora ahagarara.”
Iterambere ryapimwe: Igipimo cyo kunanirwa guhindagurika kw'ingufu cyariyongereyeho 50% (50G → 75G).
Q: 17. Ni uruhe rugero rw'ihindagurika rya ESR rya capacitors za VHE mu rugero rwose rw'ubushyuhe?
A: Igumana ubushyuhe bwa 9-11mΩ kuva kuri -55°C kugeza kuri 135°C, hamwe n'ihindagurika rya ≤22% ku kinyuranyo cy'ubushyuhe bwa 60°C, ibi bikaba ari byiza kurusha ihindagurika rya 35%+ rya capacitors za VHU.
Q: 18. Ese imikorere yo gutangira ya capacitors za VHE iragabanuka iyo ubushyuhe buri hasi (-55°C)?
A: Imiterere y’uruvange ituma ubushobozi bwo kubika ibintu bugera kuri >85% kuri -55°C (electrolyte + polymer synergy), kandi ESR iguma kuri ≤11mΩ.
Q: 19. Ni ubuhe buryo bwo kwihanganira ubwiyongere bw'amashanyarazi bwa capacitors za VHE?
A: Capacitors za VHE zifite ubushobozi bwo kwihanganira kurenza urugero: Zishyigikira voltage ingana inshuro 1.3 kuri 100ms (urugero, moderi ya 35V ishobora kwihanganira transients za 45.5V).
Q: 20. Ese capacitors za VHE zikurikiza ibidukikije (RoHS / REACH)?
A: Capacitors za YMIN VHE zujuje ibisabwa na RoHS 2.0 na REACH SVHC 223 (amategeko y'ibanze y'imodoka).
