1. Ultra-Compact SMD Design
7.0×7.0×4.0mm footprint for space-critical PCBs (reflow-compatible).
2. High-Frequency Performance
Stable at 500kHz–3MHz (Ni-Zn ferrite core, Lsat ≥10μH).
3. Low Core Loss
<15mW/cm³ @ 1MHz, 25°C (PC95 material).
4. Precision Windings
Tight tolerance (±5%) with triple-insulated wire (UL 1446).
5. Automotive Grade
AEC-Q200 qualified (-55°C to +150°C).
RF Power Modules: Class-D/E amplifiers (5–20W).
5G Infrastructure: DC-DC converters in mMIMO antennas.
Wearables: Wireless charging Rx coils (WPC 1.3).
Automotive ADAS: Isolated CAN bus power (12V→5V).
Note: Optimized for high-density, high-reliability HF circuits.
