49390-221

Overview

The Vicor 49390-221 is a through-hole bifilar common mode adapter inductor designed for power conversion applications. It provides an inductance of 220 µH at 10 kHz and exhibits a common mode impedance of 700 Ohms at 1 MHz. The component supports a typical current rating of 10.5 A with a DC resistance of 11 mOhm. This part functions as a magnetic interconnect accessory, specifically engineered to suppress electromagnetic interference in high-performance power systems.

Feature Summary

• Bifilar winding construction for enhanced common mode noise suppression
• Through-hole mounting configuration for robust mechanical integration
• High current handling capability suitable for dense power architectures

Applications

• Enterprise and high performance computing power delivery networks
• Industrial equipment and automation control systems
• Telecommunications and network infrastructure power supplies

Procurement Notes

Verify the specific manufacturing revision and RoHS compliance status directly with Vicor or authorized distributors before finalizing procurement. Confirm that the through-hole footprint dimensions align precisely with the target PCB layout. Ensure that the thermal management strategy accounts for the 11 mOhm DC resistance under maximum load conditions to prevent excessive temperature rise during operation.

Selection Notes

Select this component when designing systems requiring high common mode rejection ratios in bifilar configurations. The 220 µH inductance value is optimized for filtering applications operating at standard switching frequencies. Engineers should validate the 10.5 A current rating against peak load requirements to ensure reliable long-term performance without saturation or thermal issues in the power stage.

Part Context

This component belongs to Vicor's portfolio of modular power components and accessories. Vicor specializes in patented power delivery technologies for sectors including aerospace, defense, and automotive. The 49390-221 serves as a passive magnetic element within larger factorized power architectures, supporting the company's focus on high-efficiency power conversion solutions.

Replacement Considerations
