Mō ngā pūnga MLCC (Multilayer Ceramic Capacitor), ko tētahi āhuatanga nui hei whakaaroaro ko te Ātete Raupapa Rite (ESR). Ko te ESR o te pūnga e pā ana ki te ātete ā-roto o te pūnga. Arā, ka ine i te ngāwari o te kawe a te pūnga i te iahiko whakawhiti (AC). Te mārama ki te ESR oNgā pūnga MLCChe mea tino nui i roto i ngā tono hiko maha, inā koa ko ērā e hiahia ana ki te mahi pumau me te iti o te whakapaunga hiko.
He maha ngā āhuatanga e pāngia ana e te ESR o tētahi pūnga MLCC, pērā i te hanganga rauemi, te hanganga, me te rahi.Ngā pūnga MLCChe mea hanga i ngā paparanga maha o te rauemi uku kua whakarārangihia, me ia paparanga e wehea ana e ngā irahiko whakarewa. Ko te rauemi uku e pai ana mō ēnei pūnga ko te huinga o te titanium, te zirconium, me ētahi atu waikura whakarewa. He mea whiriwhiri pai ēnei rauemi kia puta he uara kaha teitei me te aukati iti i ngā auau teitei.
Hei whakaiti i te ESR, he maha ngā hangarau rerekē e whakamahia ana e ngā kaihanga i roto i te tukanga hanga. Ko tētahi o aua tikanga ko te whakauru i tētahi rauemi kawe hiko, pērā i te hiriwa, i te parahi rānei, hei whakapiri kawe hiko. Ka whakamahia ēnei whakapiri kawe hiko hei hanga i ngā irahiko e hono ana i ngā paparanga uku, ā, ka whakaitihia te ESR whānui. Hei tāpiri, ka taea e ngā kaihanga te pani i tētahi paparanga angiangi o te rauemi kawe hiko ki te mata o tePūnga MLCCkia nui ake te whakaiti i te ESR.
Ka inehia te ESR o te pūnga hiko MLCC i roto i ngā ohm, ā, ka rerekē pea i runga i te tono. Ko ngā uara ESR iti he mea e hiahiatia ana i te nuinga o te wā nā te mea e tohu ana i te kawe hiko pai ake me te ngaronga hiko iti ake. He pai ake ngā pūnga hiko ESR iti mō ngā tono e hiahia ana ki te mahi auau teitei, pērā i ngā pūtake hiko me ngā ara iahiko wetewete. He pai ake te pumau me te whai hua, ā, ka taea te whakahaere i ngā huringa tere o te ngaohiko me te kore he ngaronga nui.
Heoi anō, me mārama koNgā pūnga MLCCTērā pea he herenga anō hoki mō ngā mea he tino iti te ESR. I ētahi tono, ka taea e te ESR he tino iti rawa te whakaputa i te haruru kāore e hiahiatia me te mahi kore pumau. Nō reira, he mea nui kia āta whiriwhiria he pūnga MLCC me te uara ESR e tika ana mō ngā whakaritenga motuhake o te ara iahiko.
Hei tāpiri, ko te ESR oNgā pūnga MLCCKa rerekē haere i roto i te wā nā ngā āhuatanga pēnei i te koroheketanga me ngā huringa pāmahana. Ka piki ake te ESR i te koroheketanga o te pūnga hiko, ka pā ki te mahi whānui o te ara iahiko. Me whai whakaaro ki ēnei āhuatanga i te wā e hoahoa ana i ngā pūnaha hiko hei whakarite i te pono me te pumau mō te wā roa.
Hei whakarāpopototanga, he mea nui te ESR o te pūnga hiko MLCC ki te whakatau i ōna āhuatanga hiko. He tawhā nui tēnei hei whakaaroaro māu i te wā e whiriwhiri ana i ngā pūnga hiko mō ngā momo tono hiko. Ka whakapai ake ngā pūnga hiko MLCC me te ESR iti i te pai me te pumau, ā, he pai hoki mō ngā ara iahiko auau teitei. Heoi, me taurite te uara ESR ki ngā whakaritenga motuhake o te ara iahiko kia pai ai te mahi me te pono.
