1585-50UH-3A – FERROPERM

Overview

The FERROPERM 1585-50UH-3A is a high-performance RF choke meticulously designed for robust interference suppression in demanding electronic systems. Its core function is to impede high-frequency currents while allowing DC or low-frequency signals to pass, crucial for maintaining signal integrity and preventing unwanted oscillations. A key design consideration, particularly in high-current applications, is the trade-off between inductance value and core saturation. While the 50 µH rating is nominal, engineers must account for potential inductance derating under significant DC bias to ensure effective filtering without compromising circuit performance.

Key Features

• Inductance: 50 µH ± 20%
• Rated Current: 3 A
• Core Material: Ferrite
• Operating Temperature Range: -55°C to +85°C ambient
• Construction: Insulated with heat-shrink tube (INS type)
• Dimensions: [Specific dimensions would be added here if available, e.g., 12mm x 8mm x 5mm]
