High Current SMD Power Inductors - SPQ Series
Product Overview
The SPQ Series High Current SMD Power Inductors from SHENZHEN LANTU MICRO ELECTRIC TECHNOLOGY CO., LTD. are designed for demanding applications requiring low DC resistance and ultra-high current handling in a thin, space-saving profile. Featuring magnetic shielding for strong anti-electromagnetic interference and an integral construction for high reliability and vibration resistance, these inductors offer ultra-low buzz noise and low loss due to their composite structure and die-casting with low loss alloy powder. They are suitable for high-density installations and operate efficiently at frequencies up to 3MHz, making them ideal for power conversion and battery-powered devices.
