Prosperity Dielectrics Co., Ltd. (PDC), established in 1990 and listed on the OTC in 2002, is a leading Chinese manufacturer of passive components. It uniquely integrates raw material production, including ceramic powder, with the manufacture of multilayer ceramic capacitors, making it the only company in China offering full vertical integration from materials to components. In 2005, PDC formed a strategic alliance with WTC and, in 2008, merged with Hongdian Electronics, expanding its product range to include semiconducting ceramic tiles, chip resistors, and inductors. PDC is now the only domestic supplier of specialized capacitors, resistors, and inductors. With expertise in key materials, PDC develops customized electronic components, reducing production time and expanding into high-value areas such as medium-high voltage and high-precision capacitors, low-resistance resistors, and high-power components. PDC is also advancing into high-frequency and high-capacity fields. Its dielectric ceramic powders, including precious and base metal process (BME) types, have been in mass production for over 20 years, earning stable market recognition. Additionally, PDC plays a critical role in supplying materials for the communications industry.
