The RL-4400 Series of Common Mode
Chokes are designed to maximize
performance in the smallest possible
package. High inductance and high current
capabilities are achieved by selection of
premium materials.
There are three sizes available with
inductance values ranging from 390µH to
200mH and current ratings ranging from
210mA to 4 Amps.
SPECIFICATIONS:
Rated Voltage: 250V, DC to 400Hz.
Dielectric Withstanding Voltage: 2000VAC
line to line. 750 VAC Wind to Core
Temperature Rise: 50°C max.
Maximum Operating Temperature Range:
-55°C to +125°C.
