RF CHIP INDUCTORS
Application Notes
The Basics of Wire-Wound Chip Inductors
Pulse currently supplies high quality magnetic products to companies such as 3COM, Cisco, Ericsson, Intel, Marconi,
Nokia and Nortel and has been active in the field of RF engineering, since the launch of its first wire-wound 1008
chip product in 1982. Pulse now offers seven ranges of wire-wound chip from 0402 to 1206 (see table 1.0 below):
the "CD Range" with 100% compatibility to other market leaders, and the "CM and CQ ranges" with improved
electrical performance or alternative inductance values with a ceramic core construction; the FT series with a
Ferrite core construction.
In recent years, Pulse has leveraged its strength within the Telecoms and Networking industry to extend its product
range to encompass RF products for the Cable Modem, CATV, MMDS and TETRA markets. Pulse now also offers
Wide Bandwidth RF Transformers, Splitter Combiners, Couplers, Diplexers, Low Pass Filters and High Power
Impedance Matching Transformers. To explore the complete range of RF products, visit the Pulse website:

Competing Chip Inductor Types
Capacitor and resistors are available in a wide variety of sizes and component values and it is possible to purchase
almost any value, tolerance or other rating. Inductors, on the other hand, are not so readily available and engineers
may find it necessary to wind their own inductors to get a specific value of inductance.
There are mainly 3 varieties of inductor in common use today and they are wire-wound, multi-layer and drum core
chip inductors. The primary differences between these competing types are the core material used to enhance the
inductance of coil and the construction method. Wire is wound around a ceramic or ferrite bobbin or in the case of
multi-layer the coil is formed by interconnecting layers of conductive material printed on a ceramic substrate.
Table 2.0 indicates that the performance merits of wire-wound inductors versus the alternative multi-layer and drum
core platforms. If price were the only consideration then, of course, there would be no market available for wire-wound
chip inductors. But price is not the only consideration, since RF engineers must also consider the needs of the
application in terms of Q factor, Idc (maximum current carrying capacity). Rdc (resistance at dc), Tolerance and
SRF (self-resonant or series resonant frequency).
