Stable High Volatge IGBT Snubber Capacitors

Kufotokozera Kwachidule:

Chitsanzo cha Capacitor: SMJ-TC

Mawonekedwe:

1. Maelekitirodi a mtedza wa mkuwa

2. Small kukula thupi ndi unsembe zosavuta

3. Mylar tepi yokhotakhota luso

4. Kudzaza utomoni wowuma

5. Low Equivalent Series Inductance (ESL) ndi Equivalent Series Resistance (ESR)

Mapulogalamu:

1. GTO Snubber

2. Peak Voltage ndi Peak Current Absorption ndi Chitetezo pa Kusintha Chigawo mu Zida Zamagetsi

Zozungulira za snubber ndizofunikira kwa ma diode omwe amagwiritsidwa ntchito posintha ma circuit.Itha kupulumutsa diode ku ma spikes ochulukirapo, omwe angabwere panthawi yobwezeretsanso.

FAQ

Q1.Kodi ndingapezeko chitsanzo choyitanitsa chopangira filimu?
A: Inde, tikulandira dongosolo lachitsanzo kuti tiyese ndikuyang'ana khalidwe.Zitsanzo zosakanikirana ndizovomerezeka.
*Q2.Nanga bwanji nthawi yotsogolera?*
A: Zitsanzo zimafunikira masiku 3-5, nthawi yopanga misa imafuna masabata a 1-2 kuti ikhale yochulukirapo kuposa.
Q3.Kodi muli ndi malire a MOQ a fim capacitors?
A: MOQ yochepa, 1pc yoyang'ana chitsanzo ilipo.
*Q4.Momwe mungapititsire kuyitanitsa ma capacitor amafilimu?*
A: Choyamba tidziwitseni zomwe mukufuna kapena zomwe mukufuna. Kachiwiri Timabwereza zomwe mukufuna kapena malingaliro athu. Kachitatu kasitomala amatsimikizira zitsanzo ndi malo madipoziti oda yovomerezeka. Chachinayi Timakonza kupanga.

Q5.Kodi mumatumiza bwanji katunduyo ndipo zimatenga nthawi yayitali bwanji kuti mufike?
A: Nthawi zambiri timatumiza ndi DHL, UPS, FedEx kapena TNT.Nthawi zambiri zimatenga 3-5 masiku kufika.Kutumiza kwa ndege ndi panyanja nakonso.
*Q6.Kodi ndizabwino kusindikiza logo yanga pa ma capacitor?*
A: Inde.Chonde tidziwitseni mwamwambo tisanapange ndikutsimikizira kapangidwe kake potengera zitsanzo zathu.
*Q7: Kodi mumapereka chitsimikizo pazogulitsa?*
A: Inde, timapereka chitsimikizo cha zaka 7 pazogulitsa zathu.
