High Q SMD Precision Wound Inductor with Low Tolerance for RF Filter Applications

Our High-Q SMD Precision Wound Inductor is engineered to deliver exceptional performance in radio frequency (RF) filtering and signal conditioning applications. Designed for demanding RF circuits, this inductor combines ultra-low tolerance, minimal losses, and superior quality factor (Q) to ensure precise impedance matching, sharp frequency selectivity, and stable operation across high-frequency ranges.

Features

• High Q Factor: Optimized for minimal core and winding losses, achieving Q values up to 150 @ 100 MHz (varies by inductance), enabling efficient energy storage and low insertion loss in resonant circuits.

• Tight Tolerance: Precision wound construction ensures ±2% inductance tolerance, critical for maintaining consistent filter characteristics and phase stability in RF designs.

• Broad Frequency Range: Operates effectively from 1 MHz to 6 GHz, ideal for 5G, Wi-Fi 6/7, IoT, cellular infrastructure, and satellite communication systems.

• Low DCR: Advanced winding technology minimizes DC resistance (as low as 0.05Ω), reducing thermal losses and improving power handling.

• Robust Construction: Ceramic or composite core materials provide excellent temperature stability (±30 ppm/°C) and high self-resonant frequency (SRF).

• Compact SMD Package: Available in 0603, 0805, and 1206 footprints with moisture-resistant coatings, compatible with automated PCB assembly processes.

Applications

• RF bandpass/bandstop filters
