Description
The Protechnic MBT1705VS-W03 is an ultra-miniature 5 V DC Blower Fan with dimensions of 17 x 17 x 5 mm, specifically engineered for precision thermal management in high-density mobile electronics and wearable medical devices. Driven by a high-efficiency micromotor with integrated auto-restart and reverse polarity protection, this unit features a precise Max. Power Consumption of 0.6 W and a Max. Current Draw of 0.12 A at 5 V DC. Operating at an optimized rated speed for low-noise performance, it provides a dedicated directional airflow to maintain optimal temperature in space-constrained electronic environments. Constructed with a premium glass-fiber reinforced PBT plastic housing and a centrifugal impeller featuring precision dual ball bearings, this unit utilizes an integrated Flexible Printed Circuit (FPC) with a multi-pin connector for high-reliability electrical hookup in compact assemblies.
