Ultra-High K Single Layer Chip Capacitors

Ultra-High K Single Layer Chip Capacitors

Sophistication of communication equipment is essential as advanced telecommunications technologies, such as 5G, continue to develop. This is driving demand for smaller and smaller devices as requirements for higher and higher capacitances emerge. To support these new technologies, Tecdia has researched and developed a range of ultra-high K dielectrics for single layer chip capacitors (SLCs).

The Challenge:

Achieving higher dielectric constants and miniaturization of SLCs

SLCs are embedded into circuits within RF communication devices and optical transceiver modules, used for coupling, decoupling, DC block and impedance matching applications. With the commercialization of 5G using higher frequency bands, smallerhigh-frequency compatible components are required for the communication equipment. To support this, it is essential to increase the dielectric constant to realize downsizing of SLCs.

The Solution:

Developing a single layer ceramic capacitor lineup with extremely high dielectric constant

Tecdia utilizes a class IV GBBL (Grain Boundary Barrier Layer) dielectric material to achieve ultra-high effective dielectric constant materials. The dielectric constants of the materials we developed and now manufacture entirely in-house are 16,000, 30,000 and 50,000.

The GBBL structure consists of a conductive ceramic that is in contact with a thin insulating grain boundary barrier layer, resulting in a very high dielectric constant not possible with conventional dielectric materials. SLCs using this GBBL ultra-high dielectric boast excellent temperature characteristics, high breakdown voltage, and high reliability.

Key Point:

Providing products that match your application

Tecdia has a track record of developing, manufacturing, and selling SLCs used in microwave communication equipment and optical communication equipment for over 40 years. Tecdia also has been adopted by communication equipment manufacturers and optical module manufacturers around the world. Our wide ranging lineup of dielectric materials, with dielectric constants including 10, 40, 90, 130, 280, 1,600, 2,800, 16,000, 30,000, and 50,000, enables us to provide optimal solutions to our customers. We are continuing to develop novel materials to meet the needs of customers on a global scale to support advanced development efforts of communication equipment.

The Result:

The high dielectric constant of SLCs made by Tecdia contributes to the miniaturization of communication equipment. Tecdia offers not only a lineup of SLCs, but other customizable products including integrated resistor-capacitors (IRCs).
