AVX has expanded its porcelain and ceramic dielectric multilayer capacitor (MLC) chip offering to include non-magnetic termination versions that are suitable for medical devices such as MRI coils.

Designated the SQ Series, the RF capacitor series is rated at 50 to 500V DC with capacitance values ranging from 0.1 to 1,000pF.

The SQ Series offers low ESR, high Q, high current and high self-resonance frequency values.

'The SQ Series capacitors' porcelain and ceramic multilayer construction features l palladium internal electrodes as well as fine-grained, high-density, high-purity dielectric materials to keep moisture out,' said Larry Eisenberger, senior field applications engineer at AVX.

'This advanced design allows for as much as 40 per cent lower equivalent series resistance than other MLC versions,' he added.

With these high-performance materials and design, along with high current-carrying capabilities and high-quality factors, the SQ Series capacitors offer stability under the stresses of changing voltage, frequency, time and temperature.

The SQ Series capacitors are rated for operation between -55 and 125C, and feature P90 and NPO characteristics, as well as a 100 per cent tin finish.

The SQ Series capacitors are available in 0603, 0605, 0805 and 1210 case sizes.
