Technical Advantages

These Unshielded Inductor components outperform ferrite-core RF Inductor in cost-sensitive applications due to:

1. 30% lower DCR compared to equivalent shielded inductors.

2. Stable Q-factor maintenance up to 300MHz for EMI-sensitive circuits.

3. Compatibility with wave/reflow soldering processes.
   For noise suppression in Power Converter systems, pair with our EMC Filter solutions to achieve FCC/VCCI compliance.

Typical Applications

1. Consumer Electronics: TV power boards and VCR signal filtering.

2. Automotive Systems: Engine control units (ECUs) and Sensor interface circuits.

3. Industrial Controls: Power supplies for Sensor arrays and relay drivers.

4. Telecom Equipment: Mobile communication device filters and decoupling networks.

5. Power Conversion: DC-DC Power Converter modules requiring stable inductance.

Performance & Reliability

• Current Rating: IDC defined at 10% inductance drop or 20°C temperature rise.

• Environmental Resistance: MIL-STD-202E solvent compliance and humidity resistance.

• Long-Term Stability: ±10% inductance variation from -40°C to +105°C.
