Typical Applications & Why This Part Fits

• RF Signal Matching: The 56nH value and low‑profile SMD package enable clean impedance transformation in 2.4 GHz and 5 GHz wireless modules, while the 200mA current rating supports transceiver peak currents.
• High‑Frequency Noise Filtering: Its 1.2Ω DCR ensures minimal insertion loss in power‑line decoupling for IoT sensors, where every millivolt of headroom matters.
• Resonant Circuit Tuning: Stable inductance over temperature makes this inductor suitable for VCO (voltage‑controlled oscillator) bias networks – a critical need in compact GPS and Bluetooth circuits.

Key Features & Advantages

• Precision 56nH ±5%: Tight tolerance ensures repeatable filter performance without on‑board tuning, reducing calibration steps in production.
• 200mA Current Handling: Ample margin for typical RF front‑end loads, avoiding saturation even under burst transmission conditions.
• Low 1.2Ω DCR: Minimizes resistive power loss, preserving battery life in portable IoT devices.
