Description

T50 High-Current Three-Phase Toroidal Inductor / Common Mode Choke

1. Product Overview

The CHIPSEN T50 Three-Phase Toroidal Inductor is engineered specifically for high-power conversion and grid-tied systems. Built on high-permeability magnetic cores with precision heavy-gauge copper winding and a flame-retardant PCB mounting base, it delivers exceptional common-mode noise attenuation, minimal power loss, and superior phase-to-phase balance. Designed to meet stringent international automotive and industrial standards, the T50 series is the ideal magnetic solution for harsh operating environments where thermal stability and high current handling are paramount.

Parameter Category Key Electrical Parameter Typical Specification Range Test Condition / Method
Inductance & Filtering Per-Phase Inductance (L) CM: 0.5 mH - 15.0 mH | DM: 10 μH - 200 μH @ 10 kHz / 100 kHz, 0.1V, 25°C
Phase Symmetry Phase-to-Phase Balance (|ΔL|) ≤ 3.0% - 5.0% max deviation across 3 phases Automated precision winding
Current & Thermal Rated Continuous Current (Irms) 15 A - 80 A continuous ΔT ≤ 40K - 50K temperature rise @ 25°C
Saturation Margin Saturation Current (Isat) Isat ≥ 1.2 - 1.5 * Irms (L drop ≤ 20%-30%) High DC-bias testing (up to 100A)
Power Loss & DCR DC Resistance per Phase (DCR) 1.5 mΩ - 35.0 mΩ (typical) 4-wire Kelvin measurement @ 25°C
High-Voltage Safety Dielectric Withstand (Hi-Pot) 1,500 VAC - 3,000 VAC (Leakage < 5mA, 60s) Phase-to-Phase & Phase-to-Core
Thermal Class Insulation Thermal Rating Class F (155°C) / Class H (180°C) UL 1446 recognized insulation systems
Magnetic Material Core Material Options Nanocrystalline / Sendust / High-Flux Ferrite Tailored to frequency & flux density
Mechanical & Mounting Header Base & Pin Termination Through-Hole PCB Mount with Spacer Base UL94-V0 rated base, heavy copper pins

2. Key Features

  • High Current & Low Loss: Handles up to 80A continuous current with ultra-low DCR (down to 1.5 mΩ), ensuring maximum energy efficiency and low heat dissipation.
  • Precision Phase Balance: Automated toroidal winding ensures phase inductance deviation ≤ 3%, effectively eliminating neutral line offset and magnetic saturation.
  • High Dielectric Safety: Reinforced phase-to-phase insulation barriers provide dielectric withstand voltage up to 3,000 VAC (Hi-Pot, 60s).
  • Robust PCB-Mount Design: Sturdy header base with heavy-duty solder pins enables vibration-proof PCB installation and automated wave soldering.
  • Thermal Endurance: UL-recognized Class F (155°C) / Class H (180°C) insulation system, engineered for compact, fanless, or sealed enclosures.

3. Applications

  • Renewable Energy & Storage: Solar / Photovoltaic grid-tied inverters, commercial ESS power conversion systems (PCS).
  • E-Mobility: EV DC fast chargers (30kW–120kW+), onboard chargers (OBC).
  • Industrial Automation & Robotics: Variable Frequency Drives (VFD), servo motor controllers, industrial robotics power units.
  • Critical Power Infrastructure: High-capacity 3-phase industrial UPS, AI server & telecom high-voltage power supplies (HVDC).
