HDMI Common Mode Filters & Chokes (TCPWCH-2012HD)
HDMI port has been widely used in all kinds of A/V equipments with the development of HD & full HD video technology. HDMI provides ultra high transfer rate and supports hot plug and play technology. According to the latest HDMI1.4 specification, HDMI provide a max transfer rate of 4.8Gbps, which could well address the need of full HD video transmission.
DeMint has introduced the (TCPWCH-2012HD) series of low-profile choke coils. Designed for use as noise-control components adaptable to high-speed differential transmission systems, these series feature a wide variation of impedance values and the ability to match transmission-line impedance with component image impedance.
Different applications have different standards designed to govern the quality of signal waveforms. Components that will be used on such transmission lines need to have a certain level of waveform quality when they are inserted. In addition, as noise-suppression components, they need to provide noise-control effects. With the commonmode choke coils (TCPWCH-2012HD), insertion loss of HDMI waveform specifications can be satisfied without having any significant impact on initial signal waveforms, proving the capability to support high-speed signals.
All (TCPWCH) series comes a wide variety of options to meet your needs with halogen free and RoHS Directive. DeMint is able to customize and manufacture your request, with comprehensive application engineering and design support available for customers worldwide.

- Select the optimum impedance matching components in accordance with the frequencies at which noise is a problem, the cost and space.
- In the case that the chip common mode choke coil is used with ESD protection device with large capacitance, signal quality may result to fail to meet regulation.
- In the case that there are impedance mismatch to HDMI signal line, signal quality may become worse.
- Some items are under confirmation of waveform compatibility. Please contact us for latest information.
- Suppress noise for the high-speed differential signal lines.
- Low profile wound Chip constructure with standard 0805 size.
- Best EMI suppression effect, least impact of HDMI signal wave form.
