Cat.No.C31E-5 This is the PDF file of catalog No.C31E-5. No.C31E5.pdf 00.4.14 www.DataSheet4U.com MURATA entered the suppression filter field at an early stage in response to serious problems stemming from electromagnetic interference between electronic equipment. These pioneering efforts in the filter field resulted in the development and world-wide marketing of the EMI Suppression Filter (EMIFIL®). In 1979, MURATA successfully developed an on-board type EMIFIL®, thereby realizing a solution to PC board noise suppression. In 1985, the EMIFIL® class of on-board filters ware further developed to produce a chip-based EMI suppression filter, thus substantially improving noise suppression in compact electronic equipment. Based on more than thirty years of ceramic dielectric and ferrite technology experience, MURATA's full range of high-performance EMIFIL® serve to overcome and control all types of electronic-equipment noise problems. Further, MURATA's various noise suppression circuits, designed for the diversified needs of the electronic industry, offer great advantages in the pursuit of noisefree equipment, etc. Currently, MURATA is completing a system for the analy-sis and solution of noise problems. For the finest in noise suppression components, boards, and related equipment contact the nearest MURATA sales office. !ABOUT OPERATING CONDITION Noise suppression levels resulting from MURATA's EMI suppression filters (EMIFIL®) may vary, depending on the circuits and ICs used, type of noise, mounting pattern, lead wire length, mounting location, and other operating conditions. Be sure to check and confirm, in advance, the noise suppression effect of each filter, in actual circuit, etc., before applying the filter in a commercial-purpose equipment design. EMIFIL® for both DC and AC power supplies, and thru-type EMI suppression filters for high-frequency equipment (thru-type EMIFIL®) are available. For details, contact the nearest MURATA sales office.

No.C31E5.pdf 00.4.14 www.DataSheet4U.com Typical Application of EMI Suppression Filter (EMIFIL®) for DC line The main applications of EMIFIL® for DC lines are as follows: Descriptions of these applications are based on standard digital PC board. Typical applications of EMIFIL® in PC boards can be divided into four types: 1. Elimination of non desirable harmonics in high speed signal lines High speed clock signals, for example, contain higher level harmonic components, which can cause noise. These higher harmonics are reduced to within acceptable range by EMIFIL®. For relatively low noise levels, chip ferrite bead inductors and chip solid EMIFIL® (3-te
