VLS4012HBX-4R7M - TDK

VLS4012HBX-4R7M Frequently Asked Questions (FAQs)

• What is the recommended land pattern for the VLS4012HBX-4R7M?
  The recommended land pattern for the VLS4012HBX-4R7M can be found in the TDK Corporation's application note or on their website. It typically includes a rectangular pad with a size of around 3.5mm x 2.5mm, with a 0.5mm clearance around the pad.
• How do I handle the thermal considerations for the VLS4012HBX-4R7M?
  The VLS4012HBX-4R7M has a maximum operating temperature of 125°C. To handle thermal considerations, ensure good airflow around the component, use a thermal pad or heat sink if necessary, and avoid overheating the component during soldering or rework.
• What is the equivalent series resistance (ESR) of the VLS4012HBX-4R7M?
  The ESR of the VLS4012HBX-4R7M is not explicitly stated in the datasheet, but it can be estimated to be around 0.1-0.5 ohms based on the inductor's design and materials. However, it's recommended to consult with TDK Corporation or perform measurements to determine the exact ESR value.
• Can I use the VLS4012HBX-4R7M in a high-frequency application?
  The VLS4012HBX-4R7M is designed for high-frequency applications, but its performance may degrade above 100 MHz. It's recommended to consult with TDK Corporation or perform simulations to ensure the inductor meets the requirements of your specific application.
• How do I ensure the VLS4012HBX-4R7M is properly soldered?
  To ensure proper soldering, follow the recommended soldering profile, use a solder with a melting point below 260°C, and avoid applying excessive heat or force to the component. It's also recommended to use a soldering iron with a temperature control and a flux suitable for the component's termination material.
