WSB5543W-2/TR

The WSB5543W-2/TR is a surface-mount RF inductor designed for high-frequency applications, such as RF circuits, filters, and impedance matching. It features low DC resistance (DCR) and high self-resonant frequency (SRF), making it suitable for wireless communication, IoT, and RF modules.
Key specifications:
- Inductance range: Typically in the nH range (exact value depends on model).
- Compact size: Small form factor (e.g., 0402 or similar).
- High Q factor: Ensures minimal signal loss.
- Operating temperature: Wide range (e.g., -40°C to +125°C).
Common applications include RFID, Bluetooth, Wi-Fi, and 5G devices. The "-TR" suffix indicates tape-and-reel packaging for automated assembly.
For exact parameters, refer to the datasheet (manufacturer: Würth Elektronik or similar).
