Split type


Optimum applications for output cables of inverters and servo amplifiers, including use in engine rooms
Effective in suppressing common mode noise
• For suppressing low frequency noise, 150KHz¬–30MHz (RFCW-MA)
• For suppressing high frequency noise, 30MHz–1GHz (RFCW-A)
Operating temperature is from –40 to +125℃.
Compliant to the automotive vibration standard (ISO 16750-3 Ⅱ, equivalent to passenger vehicle gear shifts)
Fixed lock ensures tight mating.
It’s structure enables tape mounting.
Anti-slip means prevents core to slide after fixing.
Plastic casing is rated UL94V-2.
