The recommended PCB land pattern for NLV25T-R33J-EFD is available in the TDK Corporation's 'Chip Inductors for General Use' application note (PDF). It provides detailed information on the recommended land pattern, including dimensions and layout considerations.
The thermal derating of NLV25T-R33J-EFD is specified in the datasheet. To handle thermal derating, ensure that the operating temperature is within the specified range (−40°C to +125°C). For temperatures above 85°C, derate the inductor's current rating according to the datasheet's thermal derating curve.
The self-resonant frequency (SRF) of NLV25T-R33J-EFD is not explicitly stated in the datasheet. However, according to TDK Corporation's application notes, the SRF of similar inductors in the NLV series is typically in the range of 100 MHz to 500 MHz. For more accurate information, contact TDK Corporation's technical support or consult their application notes.
While the NLV25T-R33J-EFD is suitable for high-frequency applications, its performance may degrade above 100 MHz due to the inductor's internal capacitance and resistance. For high-frequency applications, consider using TDK Corporation's high-frequency inductors, such as the MLF series, which are specifically designed for high-frequency use.
To ensure the reliability of NLV25T-R33J-EFD in a high-reliability application, follow TDK Corporation's recommended storage and handling procedures, and ensure that the inductor is operated within its specified ratings. Additionally, consider using TDK Corporation's AEC-Q200 qualified inductors, which are designed for high-reliability automotive and industrial applications.
