| Inductance Range (L) | 5.0mH - 50mH (Customizable per noise profile) |
| Rated Current (Idc) | 1.0A - 15A (Depending on winding gauge) |
| Working Frequency | 10kHz - 500kHz (Optimized for Switching Noise) |
| DC Resistance (DCR) | 10mΩ - 300mΩ (Optimized for Low-Loss) |
| Hi-Pot / Isolation | 2500V AC - 3500V AC / 50Hz / 60s (Winding to Winding) |
| Insulation Resistance | ≥ 100MΩ @ 500V DC |
| Operating Temp Range | -40°C to +125°C (Ambient + Temperature Rise) |
| Insulation Class | Class B (130°C) Standard / Class F (155°C) Available |
| Mounting Type | Vertical Through-Hole (with Ruggedized Base) |
| Termination Interface | Tinned High-Conductivity Copper Pins (Lead-Free) |
The SQ28 Series features Square-Core Closed Magnetic Circuit technology that forms a tightly coupled magnetic loop, trapping magnetic fields within the ferrite to eliminate external shielding requirements. Precision Automated Winding Technology prevents wire overlapping and insulation abrasion, while Vacuum Pressure Impregnation creates a moisture-proof, monolithic component resistant to industrial gases and magnetostriction.
