American Technical Ceramics Corp. (ATC) is a renowned manufacturer of high-performance electronic components, founded in 1962 and headquartered in Huntington Station, New York, USA. The company designs, develops, and produces multilayer ceramic capacitors (MLCCs), single-layer capacitors (SLCs), custom thin film products, resistive components, and inductors for RF, microwave, and millimeter-wave applications. ATC's products are critical enablers in wireless communications infrastructure, fiber optic networks, medical electronics, semiconductor manufacturing equipment, defense systems, aerospace, and satellite communications. The company is recognized for its industry-leading Q factor, ultra-low equivalent series resistance (ESR), and exceptional reliability in demanding environments. ATC's multilayer capacitors include the 100 Series, 600 Series, and 700 Series, widely used in matching, tuning, and coupling applications. Single-layer capacitors, such as the 900 Series, offer high-frequency performance and high-voltage handling. Custom thin film circuits and precision resistors, including the 470 Series, serve niche applications requiring tight tolerances. With ISO 9001 and ISO 14001 certifications, ATC maintains state-of-the-art manufacturing facilities to ensure product consistency. In 2007, ATC became a subsidiary of AVX Corporation, and later, as AVX merged into the KYOCERA group, ATC's expertise has been integrated into the global KYOCERA AVX Components Corporation, strengthening its market reach. The company holds a leading position in the RF capacitor segment, serving major OEMs and defense contractors worldwide.
