Common Mode Chokes For USB, IEEE 394, Lan Interface (TCPWCH)
Common mode chokes (TCPWCH) are used in order to filter common mode electromagnetic interference (EMI) currents without de-rating under high currents and without causing signal degradation. Common mode chokes are applied to supply and return pairs of conductors and are ideal for EMI filtering of signal lines.
DeMint Electronics offers SMD Common Mode Inductors & EMI Filters (TCPWCH) in standard 0805, 1206, 1810, and 1812 size, with a maximum height of 1.2 mm, 2.0 mm, 2.2 mm, and 2.8 mm making them low profile common mode chokes available.
They provide high differential mode cutoff frequency and common mode noise attenuation across a wide frequency range, suiting them as ideal for noise suppression in super-high-speed signal lines such as DisplayPort, DVI, USB 3.x, and HDMI 2.0. The chokes are also suited for high-speed differential signal lines such as USB, IEEE1394, and LVDS, and are compatible with USB Type-C specification.
All (TCPWCH) series comes a wide variety of options to meet your needs with halogen free and feature RoHS Directive. DeMint is able to customize and manufacture your request.

Features :
- Recommended solder profile: reflow.
- Low profile and very small size SMD Design.
- Wound Chip constructure with standard 0805 to 1812 size.
- Best EMI suppression effect but least impact to data signal wave form.
Applications :
- Preventive measure against high speed signal radiation emissions such as USB, IEEE 1394 (Firewire) or LAN interface.
- Best for NB, DSC, mobile device design.
