2 High urrent 3 erminal EMI hips he high current 3 terminal chips are an extension to the Syfer 3 terminal EMI chip range, and are capable of carrying currents up to 2A. Suitable for use on D lines on pcbs, they can prevent the radiation of interference emanating from high speed signal lines and I s and also prevent the propagation of high frequency noise on power lines. Improved high frequency filtering performance is offered as a result of the D current being fed directly through the EMI chip. 1 E ± 0.3 (0.079 ± 0.012) 3.2 ± 0.3 (0.126 ± 0.012) 1.25 ± 0.2 (0.049 ± 0.008) 1.6 ± 0.2 (0.063 ± 0.008) 1.0 ± 0.15 (0.039 ± 0.006) 1.3 max.

6 Surface Mount and Pi Filters SBSP/SBSG/ SBSM Effects of mounting method on Insertion oss hilst SBSG, SBSM and SBSP filters can be mounted conventionally on pcbs, they are also suitable for mounting in a wall or partition on a board. his greatly improves the screening between filter input and output, thereby enhancing the high frequency response. Figure 1. Filters mounted on open pcb he following insertion loss curves, based on actual measurements, show the effect. It can be seen that the filters conventionally mounted (Fig. 1) exhibit a drop in attenuation at higher frequencies. he types mounted in a partition, however (Fig. 2), maintain excellent suppression characteristics to 1GHz and above.
