Description
Stable Heavy Duty AS770 Toroidal Inductor Efficient Low DCR Power Coil
Industrial Energy Node: AS770 High-Current Toroidal Power Inductor

The AS770 Series High-Current Toroidal Inductor represents a pinnacle in power magnetic engineering, specifically designed to serve as the critical energy storage and filtering hub in modern high-performance power conversion systems. This component provides a robust solution for managing high-amperage loads within a compact, vertically-mounted footprint.

Key Advantages
  • Total Magnetic Containment Architecture: Closed-loop toroidal magnetic circuit that virtually eliminates radiated EMI
  • High Saturation Current Capacity: Maintains stable inductance during massive current surges
  • Vertical Mounting for Spatial Efficiency: Drastically reduces board real estate requirements
  • Ultra-Low DC Resistance (DCR): Optimized winding geometry minimizes resistive losses
  • Superior Thermal Resilience: Rated for wide-ranging industrial environments
  • Automated Precision Manufacturing: CNC machinery ensures perfect turns-ratio consistency
  • Exceptional Vibration Resistance: Dual-lead termination with reinforced base for rigorous applications
Technical Specifications
Technical Parameter Standard Industrial Range / Value
Product Model Code AS770 High-Current Series
Inductance Range (L) 100µH - 1,000µH ± 20% (@ 100kHz / 1V)
Rated Current (Irms) 5.0A - 25.0A (Based on 40°C Temp Rise)
Saturation Current (Isat) 8.0A - 35.0A (Based on 30% Inductance Drop)
DC Resistance (DCR) 5.0mΩ - 85.0mΩ (Optimized for Efficiency)
Working Frequency Range 100kHz - 200kHz (High Frequency Support)
Core Material Selection Sendust (Fe-Si-Al) or Iron Silicon (Fe-Si)
Operating Temperature -40°C to +155°C (Including Self-Heating)
Insulation Rating Class H (180°C) or Class N (200°C)
Termination Method Vertical PC Pin or Lead Wire with Terminal
Dielectric Strength 2500V AC / 60s (Between Winding and Core)
Standard Compliance RoHS, REACH, International Safety Compliant

Engineering Insight: The Saturation Current (Isat) is the most vital metric for power system designers. Our core materials are chosen for their high flux density and "Soft Saturation" curve, providing vital safety margins during unexpected over-current events.

Advanced Manufacturing Features
  • Inherent Magnetic Shielding: Toroidal geometry provides complete circular magnetic path, eliminating radiated noise
  • High-Precision CNC Winding: Multi-spindle CNC machines monitor wire tension and speed in real-time
  • High-Purity Materials: Oxygen-free copper windings for lowest possible DC resistance
  • Vertical Base and Lead Protection: High-strength, flame-retardant polymers with reinforced lead protection
  • Vacuum Impregnation and Bonding: Dielectric resin eliminates air pockets and prevents audible buzzing
Industrial Applications
  • Consumer Electronics & Smart Appliances: High-definition televisions, gaming consoles, smart home hubs
  • Industrial Automation & Data Center Power: High-wattage server power units, industrial DC-DC converters
  • Medical Device & Laboratory Equipment: Diagnostic tools, patient monitors, imaging systems
  • Renewable Energy & Smart Grid: Solar micro-inverters, battery management systems, EV charging stations
