Nūhou ʻOihana: Nā Capacitors a me ko lākou ʻano

Nā ʻano o nā capacitors
1. Nā capacitors electrolytic

He mau capacitors polarized kēia. Hana ʻia ka anode a i ʻole nā ​​​​kikowaena maikaʻi i ka metala a ma o ka anodization ua hana ʻia ka papa oxide. No laila hana kēia papa ma ke ʻano he insulator. ʻEkolu mau ʻano o nā capacitors electrolytic i hoʻohana ʻia no nā ʻano mea like ʻole. A hiki ke hoʻokaʻawale ʻia kēia mau mea e like me kēia:

Nā capacitors electrolytic alumini
Nā capacitors electrolytic Tantalum
Nā capacitors electrolytic Niobium

A. Nā capacitors electrolytic alumini

Ma kēia ʻano capacitors, ua hana ʻia ka anode a i ʻole ke kikowaena maikaʻi i ka alumini a hana kēia ma ke ʻano he dielectric. ʻOi aku ka liʻiliʻi o ke kumukūʻai o kēia mau capacitors ma mua o nā ʻano capacitors ʻē aʻe. Loaʻa iā lākou ka hoʻomanawanui nui loa.

B. Nā capacitors electrolytic Tantalum

I loko o kēia mau capacitors, hoʻohana ʻia ka metala ma ke ʻano he electrode. Loaʻa kēia mau ʻano ma ke ʻano kēpau a me ke ʻano chip no ka hoʻopaʻa ʻana i ka ʻili. Loaʻa i nā capacitors (10 nf a 100 mf) ka mana. Loaʻa iā ia ka pono volumetric kiʻekiʻe. He haʻahaʻa ko lākou hoʻomanawanui. He paʻa loa a hilinaʻi hoʻi lākou.

C. Nā capacitors electrolytic niobium

ʻAʻole kaulana kēia mau mea e like me nā capacitors electrolytic Aluminum a me ka capacitor electrolytic Tantalum. Ua haʻahaʻa loa ke kumukūʻai a ʻoi aku ka liʻiliʻi o ke kumukūʻai.

2. Nā capacitors seramika

ʻAʻole kaulana kēia mau mea e like me nā capacitors electrolytic Aluminum a me ka capacitor electrolytic Tantalum. Ua haʻahaʻa loa ke kumukūʻai a ʻoi aku ka liʻiliʻi o ke kumukūʻai.

•Papa I-Kūpaʻa kiʻekiʻe a me nā pohō haʻahaʻa

1. ka capacitance pololei a paʻa loa
2. kūpaʻa wela maikaʻi loa
3. hoʻomanawanui haʻahaʻa (I 0.5%)
4. ka emi ʻana o ke kahe ʻana o ke au
5. Nā mea kūpaʻa a me nā oscillators

•Papa II-haʻahaʻa pololei a me ke kūpaʻa i hoʻohui ʻia i nā capacitors papa-I

1. ʻoi aku ka maikaʻi o ka volumetric a laila nā capacitors papa-I.
2. nā loli me ke ana uila biasing

3. Nā capacitors kiʻiʻoniʻoni

♦ I loko o kēia mau capacitors kiʻiʻoniʻoni, hoʻohana ʻia ka kiʻiʻoniʻoni plastik ma ke ʻano he mea dielectric. Aia nā ʻano like ʻole e like me ka polyester poly propylene, polystyrene. Loaʻa iā ia ke kūpaʻa kiʻekiʻe a me ka hilinaʻi maikaʻi ʻo kāna helu voltage he IOU a 10 KV i loaʻa kēia mau mea i ka pae o PF a me MF.

4. Ka mea hoʻonui nui

♦ Ua kapa ʻia hoʻi ʻo ia he ultra capacitor ke mālama nei lākou i ka nui o ka uku. ʻOkoʻa ka laulā capacitance mai kekahi mau farads a i 100 farads ʻo ka helu Voltage ma waena o 2.5 a 2.9

5. Ka mea hoʻopili mika

♦ He pololei kēia mau mea a hāʻawi i kahi kūpaʻa maikaʻi o ka mahana. Hoʻohana ʻia lākou i nā noi RF a me nā noi uila kiʻekiʻe. He pipiʻi lākou ʻo ia ka mea i pani ʻia ai kēia mau mea e nā capacitor ʻē aʻe.

6. Kapasitor loli

♦ Ua kapa ʻia hoʻi ʻo ia he trimmer capacitor hoʻohana ʻia lākou no ka hoʻoponopono ʻana i nā lako a i ʻole ka hana ʻana a i ʻole ka lawelawe ʻana. Hiki ke hoʻololi i kahi laulā. ʻElua ʻano o ka trimmer capacitor.
♦ Ka mea hoʻonui ʻokiʻoki seramika a me ka ea.
♦ ʻO ka capacitor liʻiliʻi loa ma kahi o 0.5 PF, akā hiki ke hoʻololi ʻia a hiki i 100PF.
Loaʻa kēia mau capacitors no ka helu volta a hiki i ka 300v hoʻohana ʻia kēia mau capacitors i nā oscillators noi RF a me nā kaapuni hoʻonohonoho.
