Ho ipapisitsoe le sekhahla sa phallo ea matla a khoheli, ferrosilicon e phahame ho feta sendust. Leha ho le joalo, sendust e na le melemo e mengata e hlahelletseng, e bonts'ang ka botlalo bo bonolo, tahlehelo ea mantlha e sa tsotelleng, botsitso ba mocheso le litšenyehelo tse tlase tsa ts'ebeliso. Li-inductors tse sebelisang li-cores tsa phofshoana tsa sendust li ka felisa lintlha tse sa thabiseng tse bakoang ke lekhalo la moea la selikalikoe sa ferrite magnetic.

lintlha ka tsela e latelang:

1. The magnetic flux density B ea ferrite e ka tlaase ho kapa e lekana le 0.5T, e leng ka tlase ho halofo ea sendust. Ke ho re, tlas'a molumo o tšoanang, polokelo ea matla ea ferrite e tlaase haholo ho feta ea sendust.

2. Ho hanyetsa mocheso oa ferrite ho tlase haholo ho feta sendust. The magnetic saturation magnetic flux density of ferrite e fokotsehile haholo tlas'a maemo a phahameng a mocheso, athe magnetic saturation magnetic flux density of sendust ha e fetohe haholo tlas'a maemo a phahameng a mocheso.

3. Ferrite e na le litšobotsi tsa ho itima lijo le botlalo. Haeba e feta boleng bo sireletsehileng ba hona joale, e ka 'na ea etsa hore mosebetsi oa inductance o oele ka kakaretso, ha Sendust e na le litšobotsi tsa bonolo le botlalo' me e ka mamella litekanyetso tse phahameng tsa hona joale.

4. Li-cores tsa Sendust li loketse haholo bakeng sa li-inductors tsa polokelo ea matla ka ho fetola lisebelisoa tsa motlakase. Ha ho bapisoa le li-air-gap ferrite kapa li-cores tsa phofo tsa tšepe tsa boholo bo lekanang le ho phunyeletsa, li-sendust cores tse nang le flux saturation e phahameng li ka fana ka matla a phahameng a polokelo.

5. Ha ho hlokahala ho fetisa motlakase o moholo oa puisano ntle le ho hlahisa li-inductors tse feletseng tsa lerata, tšebeliso ea sendust core e ka fokotsa boholo ba filthara ea inthaneteng. Hobane palo ea ho chenchana e hlokahalang e ka tlase ho ea ferrite, sendust e boetse e na le coefficient ea magnetostriction e haufi le zero, ke hore, e khutsitse haholo ts'ebetsong ea lerata kapa hona joale marang-rang sebakeng sa maqhubu a utloahalang.

6.High magnetic flux density le low core tahlehelo litšobotsi etsa sendust cores e loketseng haholo bakeng sa matla factor calibration circuits le unidirectional drive applications, tse kang flyback transformers le pulse transformers.
