Maxi & Maxi+ Series:

Single Layer Ceramics With & Without Borders

GENERAL INFORMATION

Maxi and Maxi+ are both AVX proprietary intergranular

their major constituent and have dielectric constants

exceeding 20,000 and 30,000 respectively. Grain bound-

ary barrier layer (GBBL) capacitors have been well dis-

cussed in various literature sources and, while simple in

principle, their resulting electrical properties are depen-

dent on a complex combination of materials and process

technology.

AVX’s Maxi & Maxi+ dielectrics have the distinctive

properties that are ideal for extremely broadband

by-pass capacitors. This built-in feature gives these prod-

ucts a unique disspersive effect that is illustrated in the

accompanying curves. AVX’s ability to control the

prerequisite relationships between materials and

process has resulted in dielectrics that make these

Single Layer Ceramics especially well suited for applica-

tions requiring high frequency performance well into the

millimeter band.

These GBBL dielectrics are also available in low loss

versions that are comparable to conventional barium

titanate based dielectrics. Performance is likewise similar

in that these materials exhibit a very pronounced dip at

their resonant frequency. These designs are excellent

choices for applications requiring the combined attribut-

es of very small size and precise cut-off frequencies.

Additional information on these high Q products may be

obtained by contacting the factory or your local AVX

representative.

All Maxi & Maxi+ dielectrics exhibit X7R temperature

performance of ±15% from –55°C to +125°C. Electrical

characteristics, as outlined in MIL-C-49464, will meet

those specified for Class II dielectrics, rather than the

less stringent Class IV, which typically describes GBBL

dielectrics.
