Knowles Capacitors manufactures several ranges of components suitable for use in telecom applications. We cover infrastructure needs with our high Q and Ultra low ESR ranges designed for operation in high power applications such as base station amplifiers and filtering through to Surge/Safety capacitors and Tip and Ring capacitors at the user interface. We also manufacture planar arrays, filter components and filters for telecommunication transmission line filtering and EMI protection.
