Murata provides a recommended PCB land pattern in their application notes, which can be found on their website. The recommended land pattern is typically a rectangular pad with a size of 3.2mm x 2.5mm, with a 1.2mm diameter hole in the center for the inductor's terminal.
The NFE61HT680R2A9L has a maximum operating temperature of 125°C. To ensure reliable operation, it's essential to consider thermal management in the design. This can include providing adequate airflow, using thermal vias, and keeping the inductor away from heat sources. Murata also provides thermal derating curves in the datasheet to help with design decisions.
The self-resonant frequency (SRF) of the NFE61HT680R2A9L is not explicitly stated in the datasheet. However, according to Murata's application notes, the SRF can be estimated using the following formula: SRF (MHz) = 1000 / (2 * π * √(L * C)), where L is the inductance and C is the parasitic capacitance. For the NFE61HT680R2A9L, the estimated SRF is around 150-200 MHz.
While the NFE61HT680R2A9L is designed for high-frequency applications, its performance may degrade above 100 MHz. Murata recommends using their high-frequency inductors, such as the LQP series, for applications above 100 MHz. However, if you still want to use the NFE61HT680R2A9L, you should carefully evaluate its performance using simulation tools and consider the inductor's parasitic capacitance and resistance.
To ensure the reliability and longevity of the NFE61HT680R2A9L, follow proper storage and handling procedures, avoid excessive mechanical stress, and operate the inductor within its specified ratings. Additionally, consider using Murata's recommended soldering profiles and avoiding excessive soldering temperatures.
