Additional Details

The TCE1210-900-2P-T common mode choke is constructed with a ferrite core material that provides high impedance at specific frequencies. This choke is designed to filter unwanted noise while allowing the desired differential signals to pass through with minimal attenuation. The component is commonly used in high-speed data transmission lines, where signal integrity is paramount. The '900' in the part number typically indicates the impedance value in ohms at a specific frequency. The '2P' likely relates to the number of lines or the configuration of the choke. The component is designed to withstand reflow soldering processes, making it suitable for automated manufacturing. When selecting this choke, designers should consider the operating frequency, impedance characteristics, and current handling capacity to ensure optimal performance in their application. Detailed specifications, including impedance vs. frequency curves, can be found in the TDK datasheet for this part number. The maximum rated current should not be exceeded to avoid saturation and potential damage to the choke.
