B78476A7694A003 Frequently Asked Questions (FAQs)
TDK 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 3.5mm x 2.5mm, with a 1.5mm diameter hole in the center for the inductor's terminal.
The B78476A7694A003 has a temperature derating curve specified in the datasheet. To handle thermal derating, ensure that the inductor's operating temperature is within the specified range. If the operating temperature exceeds the specified range, reduce the inductor's current rating according to the derating curve to prevent overheating and ensure reliable operation.
The self-resonant frequency (SRF) of the B78476A7694A003 is not explicitly stated in the datasheet. However, TDK provides an impedance vs. frequency graph in the datasheet, which can be used to estimate the SRF. Alternatively, contact TDK's technical support for more information on the SRF of this specific inductor.
The B78476A7694A003 is designed to meet the vibration requirements of IEC 60068-2-6, which specifies a vibration amplitude of 7.5mm and a frequency range of 10-2000 Hz. However, it's recommended to consult with TDK's technical support to ensure the inductor meets the specific vibration requirements of your application.
The B78476A7694A003 has a tin-silver-copper (SnAgCu) terminal finish, which can be soldered using a standard reflow soldering process. Ensure that the soldering temperature and time are within the recommended range specified in the datasheet to prevent damage to the inductor.
