Ferrite cores / Nanocrystalline Alloys cores etc.


Split type


Optimum applications for out-put cables of inverters and servo amplifiers, and automotive charging cables.
• For suppressing low frequency noise, 150KHz–30MHz (BFCWN-MA)
• For suppressing high frequency noise, 30MHz–1GHz (BFCWN-A)

Equivalent endurance to automotive vibration requirements (ISO 16750-3 Ⅱ)
Operating temperature is from –40 to +125℃.
Casing has anti-slip means for cable ties.
Double protection, a cable tie and the case lock prevent ferrite cores from malfunction even if the lock becomes damaged.
Low profile provides 30% downsize of conventional clamps.



Feature Sprit type, Plastic case Cable types Round type
Frequency band Low-frequency(BFCWN-NA), High-frequency(BFCWN-A) Usage high-temp., environment and signal cables
