Additional Details:

The 0805CS-681XGLC features an inductance value of 680nH with a tolerance typically around ±5% or ±10%, depending on the specific grade. Its self-resonant frequency (SRF) is typically high, allowing for operation at high frequencies without significant performance degradation. The inductor's operating temperature range is broad, usually from -55°C to +125°C, making it suitable for use in a variety of environments. The DC resistance (DCR) is kept low to minimize power losses. It is designed for reflow soldering and compatible with standard pick-and-place equipment.

The part's construction involves winding a fine wire around a ceramic core. This wirewound construction contributes to the high Q factor and current handling capability. The ceramic core provides stability and reduces losses at high frequencies. The entire assembly is encapsulated in a ceramic package for protection and durability. The terminals are typically tin-plated for good solderability.
