This SMD coil offers a very low profile solution for applications in which it’s needed a transponder vertical coil with high sensitivity in z direction and in a small surface area. It’s so a lower profile solution for those applications in which the height of the component is critical. The design has the best electrical performance in these dimensions.
This chart is a reference guide for the most common required values at working frequency of 125 kHz. Any other inductance value at
LF or tighter tolerances can be provided. Please contact our sales department for any inquiry.

Reflow soldering, vapour-phase soldering. A maximum soldering temperature of 260ºC during 10 s should not be exceed for (see recommended soldering profile with maximum and minimum temperature-time).
The reflow condition recommended is according to the machine used by our company. Big differences will arise as a result of the type of machine, reflow conditions, method, etc used.
