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) #CommonPartsLibrary #Inductor #WE-CMB

2 Line Common Mode Choke Surface Mount 90 Ohms @ 100 MHz 400mA DCR 190mOhm The ACM2012-900-2P-T002, manufactured by TDK, is a 2-line common mode filter that helps reduce electromagnetic interference (EMI) and radio-frequency interference (RFI) in electronic systems. It is built using a wire-wound chip structure and optimized for high-speed differential signals while maintaining low impact on the desired signal. Key Characteristics Component Type: Common Mode Choke / EMI Filter Lines: 2-line (for differential signal pairs) Impedance: 90 Ω @ 100 MHz Current Rating: up to 400 mA DC Resistance: ~190 mΩ max Voltage Rating: up to 50 V Package Size: 0805 (2.0 × 1.2 mm) Mounting: Surface Mount (SMD) Function Suppresses common-mode noise on signal lines Maintains low differential impedance, so signal integrity is preserved Helps systems pass EMI/EMC compliance In simple terms: It filters out noise without affecting the actual data signal. Typical Applications USB, HDMI, Ethernet lines High-speed communication interfaces Embedded systems and IoT devices Consumer electronics and industrial equipment LVDS and display interfaces #CommonPartsLibrary #Filter #ACM
