DLI makes capacitors for high frequency applications demanding near perfect, almost lossless devices. Their components use specially developed, proprietary materials tuned to provide optimized high Q, low ESR responses. 

They are the world’s largest supplier of single-layer capacitors, typically used in hybrid and high-frequency modules, offering the broadest range of material and device options.  Our multilayer capacitors include traditional “porcelain” products, as well as highly temperature-stable and extremely low ESR chips and a family of broadband blocks.

HT Series Ceramic Capacitors are small, RF-capable, Class1 parts featuring high Voltage, Current and Power ratings. They exhibit a low dissipation factor and minimum self-inductance.  These extremely rugged capacitors are carefully designed to live in the demanding world of broadcast and high-voltage industrial application.  Their structure is both simple and robust, assuring a long trouble free life.  HT Series parts feature a nonconductive, humidity-resistant, coating and a long flashover path.  They are build upon a choice of six Class I dielectrics, providing a broad range of capacitance and temperature coefficients.  Typical applications include transmitters, antennas, induction heating, X-ray, diathermy and welding.
