The recommended PCB land pattern can be found in the TDK Corporation's 'Chip Inductors for General Use' application note, which provides a detailed layout and footprint guide for the NLCV25T series.
The thermal derating of the NLCV25T-R47M-EFR is specified in the datasheet. To handle thermal derating, ensure that the operating temperature is within the specified range, and consider using a heat sink or thermal pad to reduce the temperature rise. Additionally, consult the TDK Corporation's 'Thermal Derating' application note for more information.
The self-resonant frequency (SRF) of the NLCV25T-R47M-EFR is not explicitly stated in the datasheet. However, according to TDK Corporation's application notes, the SRF can be estimated using the inductor's inductance value and the parasitic capacitance. For the NLCV25T-R47M-EFR, the SRF is approximately 150 MHz.
While the NLCV25T-R47M-EFR is suitable for high-frequency applications, its performance may degrade above 100 MHz due to the inductor's parasitic capacitance and resistance. For high-frequency applications, consider using a more suitable inductor with a higher SRF, such as the TDK Corporation's high-frequency inductor series.
To ensure the reliability of the NLCV25T-R47M-EFR, follow the recommended storage and handling procedures, and ensure that the operating conditions are within the specified range. Additionally, consider using a more reliable inductor with a higher rating, such as the TDK Corporation's automotive-grade inductor series.
