Lokacin da muke zabar samfur, yawanci muna zaɓar bisa ga abubuwan waje. Hakanan gaskiya ne ga inductor na guntu. Muna buƙatar yin la'akari da wasu abubuwan waje ko na ciki don zaɓar manajan guntu mai dacewa, wanda ke shafar guntu. Akwai dalilai da yawa don inductance

Idan samfurin yana buƙatar inductor guntu don samar da wutar lantarki mai ɗaukuwa, yawanci yana buƙatar yin la'akari da maki uku: girma, girma, kuma batu na uku har yanzu girman. Me yasa kuke mayar da hankali kan girman? Girman allon kewayar wayar hannu ƙanƙanta ne. Na'urorin hannu na yau sun haɗa da ayyuka na baya kamar MP3, MP4, da bidiyo. Ƙarin ayyuka sun ƙara yawan baturi. Don haka, don samar da ingantattun mafita, masu bincike suna inganta su sannu a hankali.

Misali, yanzu ana amfani da mai musanya buck na maganadisu don maye gurbin mai sarrafa layin da aka yi amfani da shi a baya ko kuma an haɗa kai tsaye da baturi.

Baya ga girman, manyan ƙayyadaddun ƙayyadaddun inductor dole ne su yi la'akari da ƙimar inductance, ƙwaƙƙwaran DC na nada, ƙimar saturation na yanzu, da AC impedance ESR. A lokaci guda, dangane da aikace-aikacen, ya kamata a yi la'akari da inductance mai kariya da inductance marar garkuwa.

Hakanan muna buƙatar la'akari da asarar inductor ƙarƙashin ikon AC. Canje-canje a cikin inductance ƙarƙashin AC da kowane masana'anta inductor ke bayarwa sun bambanta. Daban-daban na AC impedances da aka samar ta hanyoyi daban-daban na sauyawa sun bambanta, yana haifar da bambance-bambance a ƙarƙashin nauyin haske. Yana da matukar mahimmanci don inganta rayuwar baturi a tsarin wutar lantarki mai ɗaukar nauyi.
