Coilmaster provides multiple shielding architectures—plastic-base shielded, ferrite ring-shielded, semi-shielded epoxy types, and cost-optimized plated-core solutions. Each offers different balances of EMI suppression, mechanical robustness, thermal behavior, and cost. Engineers can match performance to their required switching frequency, footprint, or target inductance.

Closed Magnetic Architecture & Performance Spectrum

The closed magnetic path drastically reduces flux leakage, eliminating component coupling and ensuring stability in high-density PCB layouts. This architecture is leveraged across all sub-series to meet diverse needs, from cost-efficiency to extreme anti-vibration requirements.

Manufacturing Quality and System Reliability

All shielded products are produced using high-automation assembly with full automated inspection to ensure zero-defect delivery for industrial and automotive systems.
