Medical-grade isolation transformers require ultra-stable, low-loss magnetic cores that can ensure patient safety, device isolation, and continuous performance. Our nanocrystalline cores, made from Fe-based alloys, are engineered for superior magnetic efficiency and thermal reliability in critical applications such as ventilators, MRI systems, patient monitors, and surgical equipment.
These toroidal or C-cut cores exhibit nanostructured grain sizes (12~20 μm), giving them a combination of high permeability, high saturation, and extremely low core loss—essential for precision medical power systems.

Key Features
High Magnetic Saturation (Bs = 1.2T)
Allows compact transformer designs while handling peak current without saturation.
Ultra-Low Core Loss
Thanks to nanocrystalline structure and optimized annealing, loss is typically under 10 W/kg @ 20 kHz—ideal for 24/7 hospital-grade operation.
Broad Operating Temperature Range
Stable magnetic performance from –40°C to +140°C; Curie temperature rated at 570°C ensures long-term thermal reliability.
High Electrical Resistivity (ρ ≈ 100 µΩ·cm)
Greatly suppresses eddy current losses in high-frequency circuits.
Low Magnetostriction (λs = 2~3)
Reduces mechanical noise and vibration — critical in silent, patient-focused environments.
Custom Dimensions Available
OD from 4 mm to 140 mm; cross-sectional areas and inductance values fully tailored for your medical device needs.
Advantage
Galvanic Isolation: Meets stringent medical safety regulations by ensuring patient-to-device insulation.
Silent Operation: Low magnetostriction and low core loss result in nearly silent transformer operation — ideal for ICU and diagnostic rooms.
Compact & Lightweight: High permeability enables fewer windings and smaller form factor, essential in portable medical equipment.
Reliable in Emergency: High saturation and thermal resistance ensure reliable function during power surges or high-load events.
EMC Safe: Helps suppress EMI/RFI to protect sensitive analog and digital signals in medical instruments.
