OVERVIEW
Union Technology Corp. is a global supplier of ceramic chip capacitors and other specialty multilayer ceramic (MLC)
products used by electronic manufacturers.
UTC formulates the material used in the manufacture of its MLCs, including ceramic dielectric powders, electrode mate-
rials, resins, and inks. Precise raw material characterization and tight process control ensure UTC’s quality reputation as
a state-of-the-art manufacturer of ceramic capacitor products.
UTC offers the full range of standard popular EIA sizes from a 0603 to an 2225, in NPO, X7R, Z5U, and Y5V dielectrics,
in low to high voltage ratings. In order to accommodate our customers, we offer a series of high voltage parts to 10,000
volts and 6550 size.
In addition to the standard products included in this catalog, UTC designs and manufactures a significant number of cus-
tom and specialty ceramic capacitor products in various designs and configuration to address the specific needs of our
customers. Our Advanced Products Group is staffed and equipped to assist our customers with developing MLC solu-
tions for applications requiring cost effective, volumetric efficient designs.
