APPLICATIONS
Portable electronics and wireless segment includes mobile phones, Wireless LAN, HomeRF, Bluetooth
application, telecommunication and EMI countermeasure in high frequency circuits.
DESCRIPTION
Walsin Technology Corporation develops a tiny size of 1.0 x 0.5 x 0.5 mm Multi Layer Ceramic Inductor
(MLCI) consist of a rectangular block of ceramic foils on which low resistive silver metal electrodes are
contained and connected via through hole. The inner electrodes are then connected to the two terminations.
Adopt 3D EM simulation skill for product design makes Walsin Technology Corporation MLCIs provide
excellent Q_Value and Self Resonant Frequency (SRF) characteristics to address application on high
frequency band as well as on EMI suppression. The Walsin High frequency chip inductors are manufactured
by Multilayer fabrication technology providing excellent electrical performance. The inductors are supplied in
reel taping, making them suitable for automatic Pick & Place equipment.
Cooperating with environmental protection, We provided Pb-Free products for customer request.
