Syfer Technology

Company Profile:

Syfer Technology (UK)
Established in 1977 and headquartered in Norwich, UK, Syfer Technology (acquired by Knowles Corporation in 2013) is a global leader in multilayer ceramic capacitors (MLCCs) and EMI filters. Serving industries ranging from aerospace to automotive electronics, Syfer specializes in:

• Standard to high-performance capacitors for extreme conditions (high voltage, high temperature, high reliability, and high-Q applications).

• Advanced EMI filters including feedthrough, surface-mount, panel-mount, and proprietary X2Y® balanced filters.
