E04SR-A/E04SR-AB

It can be fixed easily with the nail of a resin case

It is fixable by the pedestal (E04SRMB) of an option.

E04SR200917

Technical Information

Relation between No. of Turns/Cores and Impedance.

If impedance is insufficient as a result of the cable passing through the ferrite core once (1 turn), impedance can be increased by passing the cable through it twice or three times. Impedance increases with the square of the number of turns. However, as shown in Fig. 1, because of line capacity, impedance begins to go down when the frequency exceeds a certain level, so the frequency employed should be determined carefully.

When the number of cores in use is increased, impedance goes up in proportion to the number of cores, as shown in Fig. 2.

Gaps

A split ferrite core is easily fitted to a cable fixed in place. The split core is designed to eliminate the joint gap. As shown in Fig. 3, the characteristics of the split ferrite core are almost the same as those of the non-split (standard) ferrite core. However, if dust or foreign matter should get into the joint and produce a gap, the impedance would considerably decline at low frequencies as indicated by the curve representing the gapped ferrite core. Therefore, when fitting the split core, care should be taken not to allow dust to get into the joint.

Impedance increases with the square of the number of turns. However, as shown in Fig. 1, because of line capacity, impedance begins to go down when the frequency exceeds a certain level, so the frequency employed should be determined carefully.

When the number of cores in use is increased, impedance goes up in proportion to the number of cores, as shown in Fig. 2.

Gaps

A split ferrite core is easily fitted to a cable fixed in place. The split core is designed to eliminate the joint gap. As shown in Fig. 3, the characteristics of the split ferrite core are almost the same as those of the non-split (standard) ferrite core. However, if dust or foreign matter should get into the joint and produce a gap, the impedance would considerably decline at low frequencies as indicated by the curve representing the gapped ferrite core. Therefore, when fitting the split core, care should be taken not to allow dust to get into the joint.

Technical Information

Relation between No. of Turns/Cores and Impedance.

If impedance is insufficient as a result of the cable passing through the ferrite core once (1 turn), impedance can be increased by passing the cable through it twice or three times. Impedance increases with the square of the number of turns. However, as shown in Fig. 1, because of line capacity, impedance begins to go down when the frequency exceeds a certain level, so the frequency employed should be determined carefully.

When the number of cores in use is increased, impedance goes up in proportion to the number of cores, as shown in Fig. 2.
