The Toko America Inc. Y655LY-02M=P3 is likely a shielded power inductor, similar to the Y655LY-01M=P3. The 'LY' designation indicates that it belongs to Toko's inductor product family. Shielded power inductors are crucial components in power electronics, used for energy storage and filtering in circuits like DC-DC converters and power supplies. The shielding is essential for reducing electromagnetic interference (EMI), which can affect the performance of nearby circuits. The '=P3' suffix likely designates a specific variation of the part, potentially relating to tolerance, packaging, or electrical characteristics.

Applications

• DC-DC converters (step-up, step-down, buck-boost)
• Switching power supplies
• Voltage regulators
• EMI filtering
• LED driver circuits

Features

• Shielded construction for low EMI
• High saturation current capability
• Low DC resistance (DCR) for efficient power conversion
• Surface mount design for automated assembly
• Compact size

Benefits

• Reduced noise and interference in sensitive electronic circuits
• Improved power conversion efficiency
