Medical-Grade Magnetic Components
Medical devices demand absolute reliability. Whether powering diagnostic equipment, isolating patient‑connected circuits, or filtering noise in life‑support systems, magnetic components must perform flawlessly. A transformer failure isn’t just an inconvenience; it can interrupt care, delay procedures or compromise critical monitoring.
Custom Magnetics builds transformers, inductors and coils engineered for the precision, safety and long-term stability required in medical environments. For over forty years, we have supplied custom magnetics for OEM medical equipment manufacturers, laboratory systems, imaging platforms and patient‑care devices.
Transformers Built for Medical‑Grade Performance
Off‑the‑shelf magnetics rarely meet the electrical, mechanical and regulatory requirements of medical designs. Our engineering team works from your drawings or collaborates with you to develop a winding solution that meets your voltage, isolation, leakage current and creepage/clearance needs.
Laminated core transformers support low‑frequency applications such as:
- Patient‑connected isolation circuits
- Power conditioning for diagnostic equipment
- Control electronics in laboratory instruments
- Medical-grade power supplies requiring robust thermal performance
Toroidal transformers offer compact size, low radiated field and quiet operation, which make them ideal for:
- Portable medical devices
- Home‑care and bedside equipment
- Battery‑powered diagnostic tools
- Low‑noise environments such as imaging suites
Ferrite core transformers handle the high‑frequency switching used in modern medical power converters:
- High‑efficiency switch‑mode power supplies
- DC‑DC converters for mobile carts and portable monitors
- Gate drive transformers for precision motor control
- Power modules in imaging and analytical systems
Inductors and Coils for Clean, Stable Signals
Medical electronics rely on clean, predictable signals. Noise, distortion or drift can affect readings, disrupt communication or interfere with sensitive sensors.
We manufacture air core, ferrite core and laminated inductors designed for:
- EMI/RFI suppression in patient‑connected circuits
- Filtering for imaging and diagnostic equipment
- Current sensing in infusion pumps and monitoring systems
- Harmonic mitigation in medical power supplies
Our winding methods control stray fields, saturation behavior and linearity, ensuring stable performance across the full operating range of your device.
Built for Regulatory Compliance and Reliability
Medical equipment manufacturers face strict quality and documentation requirements. Our ISO 9001:2015 certification ensures every transformer and coil is built under audited, controlled processes with full material traceability.
We support UL, CSA and IEC insulation system requirements, creepage and clearance design for medical isolation, consistent production for long‑term product lifecycles, and engineering documentation for regulatory submissions.
You receive components that meet your specifications on the first build and remain consistent through every production run.
