Inductors
For Power Line
SMD
FEATURES
• The ACL series wire-wound chip inductors are magnetically
shielded, permitting their use in high-density mounting
configurations.
• High inductance values are achieved without size increase.
• Low DC resistance ensures high Q.
ACL Series ACL3225 Type
• The temperature coefficient is low despite the magnetic
shielding. Accordingly, immunity to ambient temperature change
is high.
