Additional Details

The 0805CS-331XJBC has an inductance of 330 nH with a tolerance of ±5%. The self-resonant frequency (SRF) is typically in the hundreds of MHz range. It has a low DC resistance (DCR), which contributes to its high Q performance. The operating temperature range is typically -40°C to +125°C. The part is suitable for automated pick and place assembly. These inductors are often used for impedance matching, filtering, and tuning in RF circuits. The 0805 package size provides a good balance between size and performance. The wirewound construction allows for higher current handling compared to multilayer chip inductors. Proper soldering techniques are required to ensure reliable connection to the circuit board. The inductor is designed to minimize parasitic capacitance, which can affect its high-frequency performance.
