Organic Inductors Make Stable Amps

Sept. 5, 2012
Inductors are often taken for granted…that is, until they fail to perform (or simply fail). A new line of multilayer organic (MLO™) RF inductors from AVX Corp. is designed not to disappoint, providing high quality factor (Q) values and high self-resonant frequencies (SRFs) in compact 0402 sized housings.

Inductors are often taken for granted…that is, until they fail to perform (or simply fail). A new line of multilayer organic (MLO™) RF inductors from AVX Corp. is designed not to disappoint, providing high quality factor (Q) values and high self-resonant frequencies (SRFs) in compact 0402 sized housings. The RoHS-compliant inductors are available with values from 1 to 32 nH.

According to AVX Product Manager Larry Eisenberger, “These new inductors represent a paradigm shift from traditional low temperature co-fired ceramic (LTCC) and thin film passive SMD components. Since copper organic inductors (COIs) are polymer based, and use high conductivity copper interconnects in a multilayer fashion, the ability to fabricate these components on large-area substrates and in laser-direct imaging allow for improved cost versus LTCC and thin film technologies.”

The low-profile inductors support frequencies well above 1 GHz and feature coefficient of thermal expansion closely matched to many popular printed-circuit-board (PCB) materials for excellent reliability. They include a 100% tin finish and are rated for operating temperatures from -55 to +125°C.
