The D31FU inductor features a low resistance, low height, and small size, making it ideal for a variety of EL lamp inverter inductor applications. Its inductance range is 100-1200µH, and its resistance is 4.8-60Ω.
The D31FU is a thin, surface‑mount fixed inductor designed for EL lamp inverter applications. It features a maximum square size of 3.5 mm and a height of 1.7 mm, and it meets RoHS requirements.
The datasheet lists inductance values from 100 µH to 1200 µH, tolerance of ±20 %, DC resistance measured with a digital multimeter, and the maximum rated DC current defined by a 10 % inductance drop or a 40 °C temperature rise, whichever occurs first. Recommended pad patterns for PCB mounting are also provided. This manual is written in Chinese.

The D31FU provides inductance values from 100 µH up to 1200 µH.
Its maximum dimensions are 3.5 mm square and 1.7 mm in height.
Yes, the D31FU meets RoHS requirements.
It is the DC current that causes the inductance to drop by 10 % or the coil temperature to rise by 40 °C, whichever occurs first.
