ʻIke i nā mea pale

1. He aha ke kū'ē

ʻO ka hana o ka hoʻokuʻu ʻana i ke au i kapa ʻia ʻo resistance.ʻO kahi mea me kahi waiwai kū'ē i kapa ʻia he mea kū'ē.Hōʻike ʻia ka R(Resistor) ma ka ʻōlelo Pelekania.

2. Unite kū'ē

He tausani o K Ω megohm M Ω ka wae kumu no ka ohm Ω kona mau huina hoonui

3. Ke kumu hoʻololi o nā ʻāpana ana:

1 m Ω = 10 ³K Ω = 10⁶Ω

4. ʻAno a me ke ʻano o ke kū'ē:

4.1 Hoʻohui waiwai:

CF:Carbon Film

TF: Kiʻiʻoniʻoni Mānoanoa

MF:Metala Film

Ueaea

4.2 Hoʻokaʻawale ʻia ma ke ʻano:

Kūpaʻa paʻa.(R)

Kū'ē Semi-hoʻololi.(S-VR)

Ke kū'ē like 'ole (VR)

4.3 Hoʻokaʻawale ma ke ʻano:

pale kala kala

Kūleʻa pepa.

kaawale

4.4 Hoʻokaʻawale e like me ka mana helu:

1/16W, 1/8W, 1/4W, 1/2W, 1W, 2W, 3W… A pela aku.

Hiki ke ʻike ʻia ka mana e kona ʻano a me ka nui.ʻO ka nui o ka leo, ʻoi aku ka nui o ka mana.

5. Nā hiʻohiʻona nui o ke kū'ē:

ʻO nā ʻāpana ʻenehana nui o ke kū'ē ʻana e pili ana i ka waiwai kūʻē, ka mana helu, ka pae hewa a pēlā aku.

6. Keʻano hōʻike kū'ē:

Hiki ke hōʻike ʻia nā waiwai kūʻē a me nā hewa o nā mea pale e nā kaha kikohoʻe i paʻi ʻia ma nā mea pale a i ʻole nā ​​apo kala.ʻO nā hiʻohiʻona helu wale nō i wehewehe ʻia ma lalo nei.

Ke hoʻohana nei i ʻekolu huahelu:

ʻO nā mea pale SMT me ka hewa o 5% ka mea maʻamau i paʻi ʻia ma ka resistor e kahi helu ʻekolu-helu, me nā huahelu mua ʻelua e hōʻike ana i nā huahelu koʻikoʻi a ʻo ka huahelu ʻekolu e hōʻike ana i ka nui o 10n.

Hōʻike ʻia e ʻekolu huahelu:

Hōʻike pinepine ʻia nā mea pale pololei e nā huahelu ʻehā, nā huahelu koʻikoʻi ʻekolu mua a me ka mana ʻehā 10n.

emi iho ma lalo o 10 Ω kū'ē me ka huapalapala “R” a me nā helu ʻelua:

5R6 = 5.6 Ω 3R9= 3.9 Ω R82 = 0.82Ω

Hoʻokuʻu ʻia o ke ʻano SMD:

Hōʻike pinepine ʻia e RP××, no ka laʻana, ʻo 10K OHM 8P4R ʻo ia ka mea i haku ʻia nā pine 8 me 4 mau kūʻokoʻa kūʻokoʻa, a ʻo ka waiwai kūʻē he 10K OHM hoʻokuʻu ʻia.

Hāʻawi ʻo NeoDen i nā ʻōnaehana laina SMT holoʻokoʻa, me ka umu SMT reflow, ka mīkini hoʻoheheʻe nalu, ka mīkini ʻohi a me ka waiho ʻana, ka mīkini paʻi solder, Reflow umu, PCB loader, PCB unloader, chip mounter, SMT AOI mīkini, SMT SPI mīkini, SMT X- ʻO ka mīkini Ray, nā lako laina hui SMT, nā lako hana PCB SMT ʻāpana, a me nā ʻano mīkini SMT āu e pono ai, e ʻoluʻolu e kelepona mai iā mākou no ka ʻike hou aku:
