ʻAno mana kiʻekiʻemea pale uweahelu ʻia ma luna o 1W, a hiki i nā haneli watts, a hiki ke hoʻohana ʻia i nā wela ambient kiʻekiʻe.Hiki ke helu ʻia nā waiwai kūʻē mai kekahi mau ohms a i mau haneli kilohms, me ka pololei kūʻē maʻamau o ± 5% a me ± 10%.ʻAno mana ʻano mea pale pale wirewound no ka iwi iwi, ka wili, ka hopena alakaʻi a me ka papa pale;ʻO ka resistor wirewound he mea pale paʻa i hana ʻia i ka ʻeha uea kūʻē i ka ʻiʻo insulating, ʻo ka uea kūʻē i hana ʻia me ka nickel-chromium, manganese-copper a me nā alloys ʻē aʻe, ʻo ka skeleton insulating he alumina ceramic, nā mea encapsulation he insulating varnish, silicone, pena, seramika, alumini pūpū a pēlā aku.ʻO kā mākou mau mea pale sima maʻamau, trapezoidal aluminum casing resistors, a me ripple resistors no nā mea pale wirewound mana kiʻekiʻe, me nā mea encapsulation like ʻole.
No ke aha e pono ai i nā keʻena hoʻomalu ke hoʻohana i nā resistors wirewound mana kiʻekiʻe?
ʻAʻole pono e hoʻohana i ka mana kiʻekiʻemea pale uweano ka hoʻomalu cabinets, akā, kiʻekiʻe mana wirewound resistors pono e hoʻokō i ka hana o kā lākou mau koi koi, inā ʻaʻole pono, ʻaʻole hiki ke hoʻohana.ʻAʻole pono ka nui o nā keʻena hoʻomalu i nā resistors wirewound mana kiʻekiʻe, a ʻaʻole i loaʻa nā mea hana.No ka laʻana, ʻaʻole pono ka nui o nā keʻena hoʻomaka hoʻomaka kaʻa maʻamau i nā mea pale wirewound mana kiʻekiʻe, ʻoiai ʻo ka hoʻomaka ʻana o nā kaʻa kaʻa kaʻa e pono ai nā mea pale wirewound mana kiʻekiʻe ma ke ʻano he pale pale.
Mana kiʻekiʻemea pale uweamai 5mΩ a 100KΩ.Hana ʻia nā mea pale uea me ka uea Nichrome a i ʻole ka uea keleawe manganese, ConocoPower uea i ʻeha ma nā paipu seramika, hiki ke hoʻokaʻawale ʻia nā resistors RX20 i ʻelua mau ʻano: paʻa a hiki ke hoʻopau.
ʻO nā pōmaikaʻi o nā mea pale wirewound mana kiʻekiʻe: ke kūpaʻa pololei kiʻekiʻe, haʻahaʻa haʻahaʻa, kūpaʻa a hilinaʻi, liʻiliʻi liʻiliʻi wela, hiki ke kū i nā wela kiʻekiʻe, i ka mahana ambient o 170 ℃ hiki ke hana maʻamau.
