Syfer Technology Limited

At Knowles Capacitors we make Multilayer, High Reliability, Single Layer and Precision Variable Capacitors, EMI Filters and Thin Film Devices. Our business was formed by combining Dielectric Laboratories (DLI), Novacap, Syfer and Voltronics, each well-established specialty capacitor makers with a combined history of over 175 years, into a single organization.

Our expertise is the design and manufacture of components important to engineers in applications where function and reliability are key. The markets we serve include medical implantable and medical equipment, military, aerospace/avionics, EMI and connector filtering, oil exploration,instrumentation, industrial electronics, optical networks, telecom and automotive.

We aim to be a leader in every market we serve, to the benefit of our customers and our mutual long-term success. We achieve this by:

  • Understanding our customers’ real needs and providing products and services to meet and exceed them
  • Providing better products and services than competitors
  • Investing in product development, manufacturing processes and people
  • Insisting on the highest ethical standards and a business culture of trust, respect and open communication

DLI is a global supplier of microwave and millimeter wave components for applications demanding near perfect, almost lossless devices. Our components use specially developed, proprietary materials tuned to provide optimized Hi-Q, low ESR responses.

Novacap is recognized as a leading supplier of specialty multilayer ceramic capacitors, differentiated by offering a wide range of high-voltage, high-reliability, high-temperature and high-energy components for specialized applications.

Syfer is a premier global source for application-specific multilayer ceramic capacitors and EMI suppression filters. Our comprehensive product range includes standard and high-voltage capacitors for 10V to 10kV and case sizes from 0402 to 8060.

Voltronics is a leader in the precision, multi-turn variable capacitor market. Utilizing a clever non-rotating piston design, our parts can be confidently set to optimize the performance of a tuned circuit. Being stable with time and temperature, Voltronics trimmers are often the easiest way to get the best performance from the circuit.
