AVX Corporation, a manufacturer and supplier of advanced electronic components and interconnect, sensor, 
Source: AVX Corporationcontrol and antenna solutions, has released the new Lambda-Bridge series thermal conductors. Constructed with high-quality aluminum nitride (AlN) or beryllium oxide (BeO) materials, Lambda-Bridge thermal conductors provide efficient, cost-effective thermal management solutions with reliable, repeatable performance in four small EIA form factors: 0302, 0402, 0603 and 0805.
Designed to direct heat to thermal ground planes, heat sinks or other points of thermal interest, help protect adjacent components from hot-spot thermal loads, and improve overall circuit reliability, the series exhibits high thermal conductivity, low thermal resistance and capacitance so low that the devices are virtually transparent at RF/microwave frequencies.
Standard configurations for the new Lambda-Bridge thermal conductors currently include 0302, 0402, 0603 and 0805 EIA packages with two standard thicknesses ranging from 20 to 40 mils (T1) and 15 to 25 mils (T2), in edge-wrap (fully-metalized edge) and no-wrap styles, and with either gold-over, non-magnetic barrier terminations or gold-over-magnetic terminations. Custom configurations are also available.
AlN Lambda-Bridge thermal conductors exhibit thermal resistance values spanning 10 °C/W to 25 °C/W (T1) and 16 °C/W to 32 °C/W (T2); thermal conductivity values spanning 40 mW/°C to 100 mW/°C (T1) and 30 mW/°C to 60 mW/°C (T2); and capacitance values spanning 0.06 to 0.13 pF (T1) and 0.05 to 0.08 pF for edge-wrap versions. Non-wrapped versions have even lower capacitance values.
BeO Lambda-Bridge thermal conductors exhibit thermal resistance values spanning 7 °C/W to 16 °C/W (T1) and 11 °C/W to 21 °C/W (T2); thermal conductivity values spanning 61 mW/°C to 153 mW/°C (T1) and 46 mW/°C to 92 mW/°C (T2); and capacitance values spanning 0.05 to 0.10 pF (T1) and 0.04 to 0.07 pF for edge-wrap versions.
