High-Current 56μH 22.5A MPPT Power Inductor

Productoverzicht

This is a heavy-duty, high-frequency through-hole power inductor specifically engineered for demanding Maximum Power Point Tracking (MPPT) solar charge controllers and high-power DC-DC buck/boost converters. Designed to operate at a nominal frequency of 100 kHz with a working voltage of DC 150V, this inductor acts as the critical energy storage and filtering heart of premium industrial power conversion systems.

Featuring an advanced multi-wire parallel winding structure and high-stability magnetic cores, the inductor delivers a unique balance of high current-carrying capacity, minimal DC resistance, and soft-saturation characteristics. It is built to ensure ultra-high energy efficiency and long-term reliability in severe high-temperature environments.

Belangrijkste kenmerken

• Advanced Multi-Wire Parallel Winding: Wound with 4x AWG 15 heavy-grade copper wires in parallel. This multi-wire architecture significantly increases the effective cross-sectional area, successfully combating skin effect losses at 100 kHz while maintaining an ultra-low primary resistance of < 6.3 mΩ.

• Soft-Saturation Performance: Features a stable, low-loss magnetic powder core with an inductance coefficient (AL) of 135 nH/N². The inductance transitions smoothly from 81.41 µH at zero load to a highly stable 56.18 µH under a full 22.5A continuous DC load, preventing sudden system overcurrent drop-outs.

• Class H (180°C) Thermal Rating: Engineered to thrive in harsh environments, utilizing advanced insulation materials rated for Class H (180°C) maximum operating temperatures with an ambient operating window of -20°C to +85°C.

• Excellent Current-Carrying Leads: Equipped with robust tinned lead terminals boasting an output wire diameter of up to 5.0 mm max and a 6mm clearance grid from the coil bottom, assuring strong, low-loss vertical PCB through-hole mounting.

• Strict UL Traceability: Fully compliant and manufactured according to international safety frameworks (UL CCN: OBJY2 & OBMW2), with complete Certificate of Conformance (CoC) support.
