Cornell Dubilier is now part of Knowles and contributes capacitor technologies to the Knowles Precision Devices portfolio. The official manufacturer website presents a broad capacitor platform that includes multilayer and single-layer ceramic capacitors, high-reliability capacitors, precision variable capacitors, EMI filters and microwave components, while the Cornell Dubilier heritage adds extensive power-capacitor and energy-storage expertise. The combined offering is relevant to industrial, medical, military, space, telecom and power-electronics applications. Engineers can address DC-link filtering, energy storage, EMI/RFI suppression, pulse handling and high-voltage requirements using capacitor technologies selected for the electrical and environmental demands of the circuit. Knowles also provides RF and microwave products such as filters, splitters and couplers, extending the portfolio beyond conventional energy-storage components into high-frequency signal-conditioning functions. Current manufacturer highlights include Hiteca™ multilayer ceramic capacitors for demanding power-electronics applications and new high-Q ceramic-core inductors for mission-critical RF systems. The company also supports custom large-capacitor assemblies where board space, capacitance, voltage and mechanical integration must be optimized together. Design resources include catalogs, technical libraries and component-selection tools for multilayer and trimmer capacitors. For engineers working on converters, inverters, power supplies, aerospace electronics, medical systems or RF hardware, the combined Cornell Dubilier and Knowles portfolio provides multiple dielectric and construction technologies rather than a single capacitor type. This allows component selection to be based on capacitance density, ESR, ripple current, voltage rating, frequency behavior, reliability level and mechanical constraints specific to the application. For RF design, the practical selection process also has to consider operating bands, antenna efficiency or RF gain, impedance matching, coexistence with adjacent radios, cable and connector losses, enclosure materials and the final installation environment. The manufacturer’s development resources are therefore useful during schematic definition, PCB layout, antenna placement, prototype tuning and compliance preparation.
