Excellent EMI Suppression Capability

Inductor Filter Coils Wide Band Chokes (TCWB)

Preview

Broadband choke inductors, also known as choke coils, is a common mode ferrite as the core of the

interference suppression devices. It consists of two same size, the same number of turns of coils,

symmetrically wound on the same ferrite toroidal cores, and forming a four-terminal device.

Shown on the common-mode signal inhibits the growth of large inductor, but for differential-mode

signal showing a small leakage inductance is almost ineffective. Choke coils used in a balanced circuit

can effectively suppress common mode interference signals (such as lightning interference), while the

normal transmission line differential-mode signal has no effect.

Token’s TCWB series use of insulation between the coil core winding method. To ensure that the

transient over-voltage under the action of short circuit breakdown does not occur. And when the

instantaneous high currents flowing through the coil, the core is not saturated. The wide band choke

cores mainly used in the PC boards to filters the EMI from the outsides.

Token utilizes the latest winding technology reducing parasitic capacitance of the coil and enhancing

the ability of transient over-voltage. Token Electronics will also produce devices outside these

specifications to meet customer requirements, with comprehensive application engineering and design

support available for customers worldwide.
