Token Wirewound Ceramic Inductor Simplifies Power Management Issues.

  • Wirewound Ceramic Inductors (TRWL)

Token (TRWL) series is a wire wound and ceramic technology that offers the highest usable frequency range, highest current carrying capability, and the best Q factor of the three technologies. The combination of these three advantages ensure that design engineers will have the right product for many more high frequency applications than most competitors.

High frequency inductors are specifically used for their frequency dependent properties. Depending on the technology, size and inductance value, the inductor will pass a certain desired range of frequencies, but will block or attenuate frequencies above the desired range. This eliminates high frequency noise or interference from communications signals.

The Construction of Token (TRWL) open-type series chip wirewound ceramic inductors are designed to provide high SRFs. The full (TRWL) series conform to the RoHS directive and Lead-free. Customed designs and tighter tolerances are available on request.

Primarily, Token (TRWL) series as power inductors required by power supply circuits of multifunctional and small mobile phones must be small in size and low in height. These products must exhibit performance that is commensurate with the high power conversion efficiency of power supply circuits. Power supply circuits must also exhibit resistance to noise in the power supply state. All performance requirements of this component is expected based on the wire-wound inductors manufactured by Token.

Application of specific designs also available including different inductance values and Q specifications adjusted to frequency requirements. The (TRWL) series is supplied in tape and reel packaging ready for use with automated assembly processes. Contact us with your specific needs.
