AVX Corporation has developed a series of multilayer organic RF inductors in a 0402 case size. The RoHS-compliant devices features an inductance range of 1nH to 32nH, providing High Q and high self-resonance.

Larry Eisenberger, product manager at AVX, stated that these new inductors, which are based on a multilayer low loss organic (MLO) technology, represent a paradigm shift from traditional low temperature co-fired ceramic (LTCC) and thin film passive SMD components. He added that 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 0402 RF inductors also offer high self-resonant frequency (SRF), and can support frequencies well above 1GHz. These advanced devices are expansion-matched to printed circuit boards, allowing for improved reliability.

The 0402 inductors are ideal for RF power amplifiers, low noise amplifiers, filter networks, and MRI systems. They offer a 100 percent tin finish, and are rated for operation from -55C to 125C.
