400MHz Multilayer Inductors:

We offer multilayer inductors with inductance from 0.15nH to 330mH, and self-resonant frequencies from 1MHz to 20GHz.An integrated multilayer-type inductor structure is formed by layering ceramic materials and a coil conductor. This enables a smaller size and lower cost compared to wire wound types.While the Q factor is lower than that of the wire wound structure, the multilayer structure provides good overall balance between the L value deviation, rated current, size, price, and other characteristics, enabling use in a wide range of applications.The multilayer structure is suitable for various applications such as RF circuit matching, choke, and resonance for mobile communication equipment.

Examples of our multilayer inductor product ranges

TE Connectivity’s 3671 Series SMD High Frequency Chip Inductors have a ceramic material construction that extends the effective frequency range to 10 GHz, and are available in four compact sizes.
