39 mH @ 10 kHz 2 Line Common Mode Choke Through Hole 300mA DCR
The 744821039 is a common mode choke (CMC) designed for power line filtering. It is used to suppress electromagnetic interference (EMI), particularly common-mode noise in AC/DC power circuits and switching power supplies.
Type: Common mode choke (power line filter)
Inductance: 39 mH @ 10 kHz
Rated current: 300 mA
Number of lines: 2-line configuration
Mounting: Through-hole (radial/vertical, 4 pins)
AC voltage rating: up to 250 V
DC resistance: ~3 Ω max
Operating temperature: −40°C to +125°C
Blocks high-frequency noise on power lines
Allows normal differential current (useful signal) to pass
Improves EMC compliance of electronic systems
Reduces radio interference (RFI) in circuits
AC/DC power supply input filters
Switch-mode power supplies (SMPS)
Industrial electronics and motor drives
Household appliances and embedded systems
Devices without proper grounding (noise suppression)
