4 microwave slcs maxi & maxi+ series: single layer ceramics with & without borders general information maxi and maxi+ are both avx proprietary intergranular barrier layer dielectric formulations. both use srtio 3 as 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 ?55c to +125c. 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. sample kits are available maxi kit catalog # kitslck20ksampl includes 10 each: gh0158101ma6n, gh0258221ma6n, gh0258471ma6n, gh0358102ma6n, gh0458182ma6n maxi+ kit catalog # kitslck30ksampl includes 10 each: gh0159331ma6n, gh0259751ma6n, gh0359152ma6n, gh0459302ma6n, gh0559602ma6n ca c e c n a t i c a phw e g n ai r e p m e t h tu t are 8 - 6 - 4 - 2 - 0 2 4 6 8 - 7 0-0 6 - 5 0 - 0 4- 3 0-0 2 - 10 0 0 10 20 30 40 5 0 6 0 70 80 90 0 10 1 10 2 10 3 10 4 1 temp r eu t ar c ( e) typical delta cap (%) 5 q0 5 + e 16 + e 17 + e 18 + e 19 + e 10 1 + e 1 frequency (hz.) 0 + e 1 1 + e 1 2 + e 1 3 + e 1 4 + e 1 impedance f p 0 0 1 f p 0 2 2 f p 0 7 4 f p 0 0 0 1 typical t y p i c a l impedance vs. frequency
