[New Taipei City] With the rapid adoption of smart buildings and Industry 4.0, Power over Ethernet (PoE) technology continues to evolve toward higher power and higher operating frequencies. However, the resulting electromagnetic interference (EMI) challenges often become the final barrier before a product can be brought to market. To simplify the development process, LinkCom Manufacturing Co., Ltd. (TPE 6821) today announced a system-level filtering solution for PoE applications, integrating PoE transformers + common-mode chokes + molded inductors + LAN transformers. Through precise component matching, this solution is designed to significantly reduce customers’ tuning and debugging costs.

Core of the Solution: From “Single-Component Purchasing” to “System Optimization”
In traditional R&D workflows, engineers often source transformers and inductors from different vendors, overlooking parasitic coupling effects between components. Based on extensive EMI laboratory data, the technical team at LinkCom Manufacturing Co., Ltd. (TPE 6821) has found that pairing a PoE transformer with a common-mode choke of specific impedance characteristics, and supplementing the output stage with a high-magnetic-shielding molded inductor, provides the most effective suppression of radiated noise from 30 MHz to 1 GHz.

To ensure stability and compatibility of the complete PoE system within enterprise LAN architectures, LinkCom Manufacturing Co., Ltd. (TPE 6821) validates its solutions in accordance with IEEE 802.3 standards, using industry-standard Ethernet compliance test equipment and services. These validations include PSE/PD behavior, long-distance transmission, temperature rise, and load characteristics. Measurement procedures using compliance tools from Tektronix and other vendors ensure that the combined solution—PoE transformer + common-mode choke + molded inductor + LAN transformer—meets stringent performance and radiated emission requirements under real-world network deployment conditions.

Why a “One-Stop Solution” Is Key to Business Profitability
For project managers and procurement decision-makers, solving EMI issues is no longer just an engineering challenge—it is a critical factor affecting time-to-market and total cost:
•    Significantly reduced launch risk: Precise matching of transformers and peripheral inductors (common-mode chokes and molded inductors) helps avoid costly last-minute redesigns, retooling, or circuit changes due to EMI failures.
•    Optimized sourcing and supply chain management: A complete, validated component set simplifies supplier communication and ensures compatibility and long-term supply stability of critical parts.
•    Improved end-user satisfaction: High-quality magnetic components reduce operating noise and heat generation, extending product lifetime and strengthening brand reliability.
•    Compliance with international standards: Pre-validation against strict global environmental and EMC regulations enables faster entry into overseas high-end markets.
