Additional Details

The TCTOBL0J157M8R-ZK1 typically features a compact surface mount package. It is designed to be used in applications where the signal frequency is relatively high, requiring the filter to have low insertion loss at the operating frequency while providing high attenuation of common mode noise. The common mode cutoff frequency is typically above 100MHz. These filters are crucial in modern electronics to meet strict EMI/EMC standards and to ensure reliable data transfer. It supports high-speed data transmission standards while mitigating common mode noise which could lead to data corruption or system malfunction. The filter's performance characteristics are usually specified in terms of common mode rejection ratio (CMRR) and differential mode insertion loss over a frequency range.
