AVX Develops High Q, Low ESR Multilayer Organic RF Capacitor

Designated the MLOC Series, the advanced organic RF capacitors maintain high Q and high self resonance while providing low ESR values at high frequencies. The capacitors, based on AVX’s patented multilayer low loss organic (MLO) technology, are polymer-based organic capacitors that use high-conductivity copper interconnects in a multilayer fashion.

The ability to fabricate these components on large area substrates with sophisticated laser direct imaging allows for improved cost benefits and tolerance control. The end result is a low profile, low ESR and high-performance RF capacitor. In addition, the MLOC Series is expansion matched to printed circuit boards to allow for improved reliability.

“AVX’s new line of organic capacitors represent a paradigm departure from traditional passive SMD components,” said Larry Eisenberger, product manager at AVX. “The multilayer low loss organic RF capacitor’s state-of-the-art design ultimately increases performance characteristics while decreasing costs.”

The RoHS-compliant RF capacitors are 50 VDC to 250 VDC rated with capacitance values ranging from 0.1 pF to 2.5 pF with capacitance tolerance to +/- 0.02 pF. Available in 0603 case size with a 100% tin finish, the MLOC Series features stable NPO characteristics with an operating temperature range of -55°C to +125°C.

The MLOC Series surface mount capacitors are ideal for usage in RF power and low noise amplifiers, filter networks, and MRI systems.
