BU15-2721R6BL - COILCRAFT

BU15-2721R6BL Frequently Asked Questions (FAQs)

• What is the recommended land pattern for the BU15-2721R6BL?
  The recommended land pattern for the BU15-2721R6BL is a rectangular pad with a size of 2.5 mm x 1.5 mm, with a non-solder mask defined (NSMD) pad shape. This is to ensure proper soldering and to prevent solder from flowing onto the adjacent pads.
• Can I use the BU15-2721R6BL in a high-temperature environment?
  The BU15-2721R6BL is rated for operation up to 125°C, but it's recommended to derate the current rating by 1.5% for every degree above 80°C to ensure reliable operation. Additionally, the inductor's temperature coefficient of inductance (TCI) should be considered when operating at high temperatures.
• How do I handle the BU15-2721R6BL's magnetic shielding?
  The BU15-2721R6BL is a shielded inductor, which means it has a magnetic shield to reduce electromagnetic interference (EMI). To ensure proper shielding, the inductor should be placed on a solid ground plane, and the shield should be connected to the ground plane through a low-impedance path.
• What is the BU15-2721R6BL's self-resonant frequency (SRF)?
  The SRF of the BU15-2721R6BL is not explicitly stated in the datasheet, but it can be estimated using the inductor's inductance and capacitance values. A rough estimate of the SRF can be calculated using the formula: SRF ≈ 1 / (2 * π * sqrt(L * C)), where L is the inductance and C is the capacitance.
• Can I use the BU15-2721R6BL in a high-frequency application?
  The BU15-2721R6BL is designed for high-frequency applications, but its performance may degrade above 100 MHz due to the inductor's internal capacitance and resistance. It's recommended to evaluate the inductor's performance in the specific application and consider using a different component if necessary.
