Overview
The WCM4532F2SV-421T32-HI is a two-line common mode choke designed for surface mount applications. It exhibits an impedance of 420 Ohms at 100 MHz and supports a current rating of 3.2 Amperes. The component features a low direct current resistance (DCR) of 55 milliohms. Manufactured by TAI-TECH Advanced Electronics Co., Ltd., this device utilizes a horizontal package configuration with four pad connections, ensuring reliable integration into compact electronic circuits requiring effective noise suppression.
Feature Summary
- Provides effective common mode noise suppression for dual-line signal paths
- Features low direct current resistance to minimize power loss
- Constructed with a horizontal surface mount package for space efficiency
Applications
- Noise filtering in high-speed data transmission lines
- Signal integrity protection in portable communication devices
- EMI suppression in automotive infotainment systems
Procurement Notes
Verify the specific impedance tolerance and current derating curves against your circuit requirements before finalizing the design. Confirm that the horizontal package dimensions align with your PCB footprint constraints. Ensure compatibility with your assembly process regarding thermal profiles during soldering. Cross-reference the manufacturer's latest datasheet to confirm RoHS compliance status and material specifications for regulatory adherence.
Selection Notes
Select this component when dual-line noise cancellation is required in space-constrained designs. The low DCR makes it suitable for applications where signal attenuation must be minimized. Consider the 3.2A current rating to ensure adequate headroom for peak operational loads. Evaluate the 420 Ohm impedance at 100 MHz to verify effectiveness against target interference frequencies.
Part Context
This part belongs to the WCM series of common mode chokes from TAI-TECH Advanced Electronics Co., Ltd. The series focuses on surface mount solutions for EMI suppression. The model number indicates specific electrical characteristics and physical packaging details relevant to modern automated assembly processes.
Replacement Considerations
Check for parts with identical 420 Ohm impedance at 100 MHz and similar 3.2A current ratings. Verify that substitute components match the horizontal package outline and terminal configuration to ensure mechanical compatibility without PCB redesign.
