New Components: Military Through Mobile Phones
December 31, 1969 |Estimated reading time: 2 minutes
AVX expanded its AntennaGuard series; Murata introduced an 0302 capacitor array for dense and miniaturized assemblies; Gowanda Electronics released a military-approved QPL inductor range.
Gowanda Electronics introduced a military-approved RF inductor series, on the military's qualified product list (QPL) per MIL-PRF-83446. Gowanda is focusing on the military market through additional QPL pursuits for RF and power components. The component manufacturer's MLRF3013 series adds an enhanced RF inductor option for military, aerospace, and defense sectors. This includes use in various communications applications including space, satellite, radio, sonar, guidance, and GPS. Applications for this series could include RF signal circuitry in communications equipment, test & measurement equipment, medical diagnostic equipment, and industrial process control equipment, as well as other systems. To achieve military qualification, the company completed extensive qualification testing in-house with a newly constructed environmental lab, built to increase Gowanda's involvement in the military market. Gowanda's MLRF3013 series was subsequently added to the Defense Supply Center Columbus (DSCC) QPL for MIL-PRF-83446 (specifically -31, -32 and -33). Technical specifications for products in the MLRF3013 series include inductance from 0.10 to 1000 µH and current ratings from 1380 to 28 mA. Inductor cores consist of phenolic, iron, or ferrite, as determined by the specific technical requirements. Gowanda offers variations to the MLRF3013 design to meet the specific requirements of an application. The company has many other product series under test for QPL approval.

Murata Electronics North America debuted its 1.0 µF static capacitance 0.9 × 0.6 mm (0302) two-element capacitor array for reducing surface area and mounting costs. The model suits use as a decoupling capacitor for mobile phones and PCs, as well as digital audio/visual equipment. Miniaturization and high-performance features were the focus of designing this capacitor array, Murata representatives report. They assert that the array can realize static capacitance more readily than its single monolithic counterpart, due to design elements. Murata used its proprietary dielectric material technology to enable 1-µF capacitance per element in the 0302 form factor. The capacitor array joins Murata's GNM series. Its reported benefits include reduced board surface area occupied and lower placement cost due to high-density mounting. For more information, visit www.murata.com.
AVX Corporation expanded its AntennaGuard series of low-capacitance multilayer varistors (MLVs) to include a sub-1-pf version. Designed to provide a one chip solution for protecting high-speed digital interfaces, RF antennae, and RF amplifier circuits against ESD events, the application specific, bi-directional transient voltage suppressor provides minimal signal distortion and low insertion loss. The low-profile 0402 MLV features a fast response time to ESD and can withstand successive 1-k strikes at 8 kV (IEC 61000-4-2). The MLV also minimizes the parasitic capacitance and signal distortion to maximize the signal strength and speed, reports AVX representatives. Initial offerings include 0.8-pf capacitance at 10 and 15 V rating in 0402 case size. High-speed data lines it protects include HDMI, FlexRay, RF circuits, analog sensors, GPS antenna, etc. For more information, see www.avx.com.
