How to Select EMI Filters for Medical Devices
Your Guide to Reliable, High-Performance EMI Filtering for Critical Healthcare Applications
Why EMI Filtering Matters in Medical Equipment
Electromagnetic interference (EMI) is a silent disruptor in today’s high-frequency medical environments. From diagnostic imaging systems to portable life support equipment, medical devices rely on clean and uninterrupted power and signal transmission. Without proper EMI filtering, signal distortion and equipment malfunction could compromise patient safety.
At LCA Mic, we specialize in high-reliability EMI filters engineered for mission-critical applications — including life-saving medical systems.
Step 1: Know Your Device’s Sensitivity and Standards
Different medical devices operate under varying degrees of susceptibility to EMI:
- MRI & CT Systems: demand ultra-low noise and minimal leakage current
- Portable Defibrillators: require compact, robust filters with stable performance
- Patient Monitoring Devices: must comply with IEC/EN 60601 standards
Tip: LCA Mic’s filters are designed to help you meet FDA, EMC Directive (2014/30/EU), or IEC 60601-1-2 compliance efficiently.
Step 2: Choose the Right Filter Type
| Filter Type | Ideal For | LCA Mic Product Example |
