A simplified electromagnetic interference (EMI) model is given for a multi-pins connector based on the assumption of nearest interaction between pins. Method of moments (MOM) is used in the calculation of per unit length capacitances. The accuracy of the model for high frequency signals is discussed. Crosstalk betwen pins are simulated in frequency domain and time domain. Simulating results may be helpful in the decreasing of EMI in connectors.
