Inductors have low DC resistance and high Q values

A line of multilayer RF ceramic inductors with low DC resistance, high Q values, self-resonant frequency, and reliability, has been introduced by Pulse Electronics. The line includes the 0201CC series whch are 1.0-100nH, with a low DCR and high Q, the 0402CC series which are 1.0-270nH, with a low DCR and high Q and the 0402CH series which are 1.0-15nH, with a very high Q.

The multilayer inductors come in standard surface mount footprints and are made of a monolithic non-organic substance that gives them a tighter tolerance and lower value of inductance in a small size compared to traditional wire-wound inductors. Their high Q value provides consistent, stable signal transmission at high frequencies.

The inductors, which are RoHS compliant, are sold in tape and reel and are suitable for use in wireless devices, broadband circuits, RFID devices, RF transceivers, modules, and medical devices.

"Pulse Electronics' high frequency ceramic chip inductors can be used as drop in replacements for some wire-wound inductors, resulting in higher reliability while reducing cost," said Chad Oblak, Senior Product Manager, Pulse Electronics. "Our customers now can choose from either our traditional wire-wound chip inductors or our new multilayer inductors."
