Additional Details

The LB2012T680K has an inductance value of 68μH with a tolerance of ±10%. The rated current and DC resistance (DCR) are specified in the manufacturer's datasheet. The high Q factor minimizes energy loss in the circuit, leading to improved performance. The self-resonant frequency (SRF) indicates the frequency at which the inductor's impedance reaches its maximum, and it should be significantly higher than the operating frequency to ensure proper operation. The multilayer ceramic construction provides excellent mechanical strength and environmental stability.

Proper soldering techniques are essential for reliable mounting. Refer to Taiyo Yuden's application notes for recommended soldering profiles and handling precautions. The component is designed for surface mount technology (SMT) and can be easily integrated into automated assembly processes. Its compact size makes it suitable for high-density circuit boards.
