GT2011 vs FP3415-351 Pulse Electronics Transformers: 7.5mm or 375W?

In industrial design, the choice between ultra-compact footprints and high-power delivery defines system capabilities. Pulse electronics Transformers bridge this gap, yet selecting between models like GT2011 (7.5mm) and FP3415-351 (375W) demands understanding their core technical divergence.

The Thin Profile Champion: GT2011

Optimized for space-constrained applications, the GT2011 excels with:

  • 7.5mm height – Enables stacking in 20+ layer AI server PCBs

  • 30pF max coupling capacitance (@100kHz) – Critical for signal integrity in 5G base stations

  • 1:1 turns ratio – Preserves pulse waveform fidelity in broadband PLC systems

  • 3200VAC Hi-Pot isolation – Meets medical/industrial safety thresholds

Ideal for: IoT gateways, edge computing nodes, and high-density communication boards.

The Power Density Leader: FP3415-351

Engineered for energy-intensive systems, FP3415-351 delivers:

  • 375W continuous power (@50kHz) – Powers SiC-based EV traction inverters

  • 1:6 turns ratio – Boosts voltage for 800V battery platforms

  • 98A peak current tolerance – Handles surge loads in solar microinverters

  • 389V surge voltage resistance – Exceeds automotive-grade requirements

Ideal for: Industrial motor drives, renewable energy converters, and fast-charging systems.

Technical Crossroads: 5-Parameter Showdown

Parameter GT2011 (High-Frequency) FP3415-351 (High-Power)
Core Mission Signal integrity preservation Energy transfer efficiency
Frequency Range DC-100MHz+ Optimized for 50kHz switching
Thermal Design Passive cooling sufficient Requires heatsink/active cooling
Standards RoHS, EN 61558 IEC 60851, AEC-Q200 (auto)

Application-Driven Selection Guide

  1. Choose GT2011 When:

    • Designing 20+ layer server PCBs (height <8mm)

    • Transmitting sub-μs pulses in radar/PLC systems

    • Needing <1.5μs rise time for precision timing

  2. Choose FP3415-351 When:

    • Driving SiC/IGBT modules in 800V EV architectures

    • Demanding >300W continuous power in hostile environments (-40°C to +85°C)

    • Managing 16.3A surge currents during motor startups

Beyond "Or": Synergistic Solutions

Modern pulse electronics transformers increasingly merge both paradigms. Ferrtx’s latest GT Series prototypes achieve:

  • 5.9mm height with 200W power capacity

  • PTFE-base windings reducing capacitance to 22pF

  • Integrated heat pipes dissipating 15W/cm²

The Engineer’s Verdict

Selecting between 7.5mm and 375W isn’t about superiority – it’s about system priorities:

  • Signal-sensitive designs? GT2011’s low capacitance prevents waveform distortion.

  • Power-hungry applications? FP3415-351’s copper windings handle joule heating.
