Product Description
A ferrite core that can be attached to cables with a single-action.
[Features]
·The high-frequency absorption property of ferrite gives it superiority in absorbing high-frequency noise
·Ferrite core is integrated with the resin case
·Effective against common mode noise and does not affect signal quality
[Applications]
·Cable noise prevention for various electronic equipment from PCs and other consumer products to medical equipment and industrial machines
·Used when cables are affected by their own unnecessary radiation, external noise, static electricity and so on
·Effective when used with cables turned for noise with relatively low frequencies such as in power supply lines
Product specifications

External appearance of Undivided Ferrite Core
- Because a ferrite core is integrated with the resin case, this product can be attached to interfaces and power cables with a single-action.
- Supports from ø3.0 to 26.0 (applicable cable diameter 3.0 to 26.0 mm).
- Effective for both normal mode noise and common mode noise, and can be expected to provide effect regardless of the kind of electromagnetic noise.
- If the impedance is not enough with 1 turn (just through the cable), it is possible to increase the impedance by increasing the number of turns such as 2 turns and 3 turns. Impedance increases in proportion to the square of the number of turns. When this product is used at a high frequency, the impedance decreases when the frequency exceeds a particular frequency due to the line capacity; therefore, it is necessary to consider the compatible frequency.
- The lineup includes large size products that support thick cables such as power cables for industrial equipment and simultaneous winding of multiple cables.
- Can be fixed in various methods such as the foot and base of the product itself.
- Ideal for cases where it is difficult to install the ring ( = undivided) type, such as when the cable already has a connector.
