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.
