NLCV25T-100K-EFRD - TDK

NLCV25T-100K-EFRD Frequently Asked Questions (FAQs)

• What is the recommended PCB footprint for the NLCV25T-100K-EFRD?
  The recommended PCB footprint for the NLCV25T-100K-EFRD is a rectangular pad with dimensions of 3.5mm x 2.5mm, with a 1.5mm diameter hole in the center for the inductor's lead.
• How do I handle the inductor's thermal considerations?
  The NLCV25T-100K-EFRD has a maximum operating temperature of 125°C. Ensure good airflow around the inductor, and consider using a heat sink or thermal pad if the inductor will be operating near its maximum current rating.
• What is the inductor's self-resonant frequency (SRF)?
  The SRF of the NLCV25T-100K-EFRD is not explicitly stated in the datasheet, but it can be estimated to be around 100-150 MHz based on the inductor's construction and similar products from TDK Corporation.
• Can I use the NLCV25T-100K-EFRD in a high-frequency switching application?
  While the NLCV25T-100K-EFRD is suitable for high-frequency applications, its core material and construction make it more suitable for lower-frequency applications (e.g., 100 kHz to 1 MHz). For higher-frequency applications (e.g., > 10 MHz), consider using a different inductor with a higher SRF.
• How do I ensure the inductor's reliability and prevent failure?
  To ensure reliability, follow proper PCB design and assembly guidelines, avoid exceeding the inductor's maximum ratings, and consider using a fuse or overcurrent protection to prevent damage from excessive current.
