WCM 4532F2SV-900T40-HI

Overview

The WCM 4532F2SV-900T40-HI is a surface mount common mode choke manufactured by TAI-TECH Advanced Electronics Co., Ltd. This component features a two-line configuration designed for noise suppression in high-speed data interfaces. It exhibits an impedance of 90 Ohms at 100 MHz and supports a current rating of 4 Amperes. The device utilizes a compact 4532 (1812 metric) package, ensuring low profile integration into dense circuit boards. Its direct current resistance is specified at 50 milliohms, facilitating efficient power transmission with minimal loss while maintaining effective electromagnetic interference filtering capabilities.

Feature Summary

• Dual-line architecture for simultaneous signal path protection
• High-frequency noise attenuation with 90 Ohm impedance characteristic
• Low DC resistance design to minimize insertion loss
• Surface mount compatibility for automated assembly processes

Applications

• USB 3.0/3.1 interface lines
• HDMI signal processing circuits
• DisplayPort data transmission paths
• General high-speed digital bus filtering

Procurement Notes

Verify the specific impedance tolerance and current derating curves against the official TAI-TECH datasheet before finalizing the design. Confirm that the 4A rating aligns with peak operational requirements rather than just continuous current. Ensure the 4532 footprint matches the PCB layout constraints. Cross-reference the RoHS compliance status with current environmental regulations applicable to the target market.

Selection Notes

Select this component when dual-channel noise suppression is required for differential pairs operating at frequencies around 100 MHz. The 90 Ohm impedance value suits standard USB and HDMI standards. Consider the 4A current capacity for power delivery lines or high-current data buses. The 50mOhm DCR makes it suitable for applications where voltage drop must be minimized. Evaluate thermal performance if multiple units are placed in close proximity on the board.

Part Context

This part belongs to TAI-TECH's WCM series of common mode chokes, specifically engineered for surface mount technology. The 4532 package size offers a balance between electrical performance and space efficiency. It is distinct from single-line filters and provides balanced noise cancellation for paired conductors. The product line focuses on meeting the stringent EMI requirements of modern consumer electronics and computing devices.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and impedance profiles if considering alternative manufacturers. Ensure any replacement maintains the 4532 footprint and 4A current handling capability.
