Nā mea palehoʻohana nui ʻia i nā kaapuni uila, e pāʻani ana i kahi kuleana koʻikoʻi i ka hoʻomalu ʻana i ke kahe o ke au uila. Aia nā ʻano like ʻole o nā resistors ma ka mākeke, a me ka nānā ʻole ʻana i ko lākou ʻano, aia lākou āpau i kā lākou mau ʻokoʻa wela ponoʻī, ʻo ia hoʻi, ʻo kēlā me kēia resistor ke hoʻololi ʻia e ka mahana. Ma kēia ʻatikala, e ʻimi mākou i ka manaʻo a me ke koʻikoʻi o nā koena wela o Resistors.
ʻO ZENITHSUN nā ʻano pale pale nui
He aha ka Mahana Coefficient o Resistor?
ʻO ka helu wela o kahi pale, i hōʻike ʻia e ka hōʻailona α (alpha), e hōʻike ana i ka loli ʻana o ke kūpaʻa me ka mahana. Hōʻike maʻamau ia i nā ʻāpana o ka miliona no ka degere Celsius (ppm/°C). ʻElua mau ʻano nui o nā coefficient wela: maikaʻi a maikaʻi ʻole.
ʻO ke koena wela maikaʻi (PTC): ʻO nā mea pale me kahi koena wela maikaʻi e hōʻike i ka piʻi ʻana o ke kūpaʻa i ka piʻi ʻana o ka wela. He mea maʻamau kēia ʻano i nā mea i hoʻomaikaʻi ʻia ka conductivity uila me nā wela kiʻekiʻe, e like me kekahi mau ʻokikene metala.
ʻO ke koena wela maikaʻi ʻole (NTC): I ka hoʻohālikelike ʻana, ʻike nā mea pale me kahi koena wela maikaʻi ʻole i ka emi ʻana o ke kūpaʻa i ka piʻi ʻana o ka mahana. ʻIke pinepine ʻia kēia i nā semiconductor a me nā mea ʻē aʻe kahi e emi ai ka conductivity me ka piʻi ʻana o ka mahana.
Ka Huli Hoʻololi Kūʻē ma muli o ka Mahana (Laʻana)
Ma lalo o nā kūlana hea e pono ai ka helu wela o amea pale palee noonooia?
ʻO ka noʻonoʻo ʻana i ka coefficient wela o kahi resistor he mea nui ia i kēia mau kūlana:
1. Nā kaiapuni me nā hoʻololi wela nui: Inā hōʻike ʻia kahi kaapuni a i ʻole ka uila uila i nā loli wela nui i ka wā e hana ai, lilo ka koena wela o ka resistor i mea nui. I kēia hihia, hiki i ke koho ʻana i kahi resistor me kahi coefficient wela kūpono ke hōʻoia i ka paʻa o ke kaapuni ma luna o nā mahana like ʻole.
2. Kaapuni pololei: Ma kekahi mau kaapuni e koi ana i na waiwai kū'ē pololei loa, ʻoi aku ka nui o nā noi e like me ke ana, nā mea ʻike, a me nā mea hoʻonui pololei, pono e noʻonoʻo ʻia ka coefficient wela o ka resistor. Pono pinepine nā kaapuni pololei e hāʻawi i ka puka kūpono a paʻa ma luna o nā mahana like ʻole.
3. Nā Hana Hana Hana: Ma kekahi mauʻoihanaʻoihana, hiki ke hoʻopiliʻia nā mea hana e nā wahi wela kiʻekiʻe a haʻahaʻa paha. I kēia hihia, ʻo ka coefficient wela o ka resistor he mea hoʻolālā koʻikoʻi no ka hōʻoia ʻana ʻaʻole i hoʻopilikia ʻia ka hana o ke kaapuni e nā loli wela.
4. Ka uku pānaʻi: Pono kekahi mau noi i ka hoʻohana ʻana i nā mea pale no ka uku wela e hōʻoia i ka hana maʻamau o ke kaapuni ma lalo o nā kūlana wela like ʻole. I kēia hihia, pono e koho i kahi resistor me kahi coefficient mahana kūpono.
ʻO ke koho kūpono o nā resistors e hōʻoia i ka paʻa a me ka pono o nā ʻōnaehana uila. Pono nā ʻenekinia a me nā mea hoʻolālā e loiloi pono i nā ʻano wela o nā resistors e hoʻokō i nā koi kikoʻī o kā lākou noi a hana i nā ʻōnaehana uila paʻa a hilinaʻi.
Ke koho ʻana i kahi resistor, ʻike pinepine ʻia ka ʻike coefficient wela o ka resistor i ka pepa kikoʻī i hāʻawi ʻia e ka mea hana.
Shenzhen Zenithsun Electronics Tech. He ʻoihana ʻo Co., Ltdnā mea palemea hana, he 20 mau makahiki o ka ʻike, a he hui ʻenehana loea e kōkua i nā mea hoʻohana e koho i nā mea pale kūpono.
