CVH252009-3R3M - Bourns

CVH252009-3R3M Frequently Asked Questions (FAQs)

• What is the recommended land pattern for the CVH252009-3R3M?
  The recommended land pattern for the CVH252009-3R3M is a rectangular pad with a size of 2.5 mm x 1.3 mm, with a non-solder mask defined (NSMD) pad shape.
• How do I handle the self-resonance frequency of the CVH252009-3R3M?
  The self-resonance frequency of the CVH252009-3R3M is typically around 100 MHz. To minimize the effects of self-resonance, use a series resistor or a parallel capacitor to dampen the resonance, or use a different inductor with a higher self-resonance frequency.
• Can I use the CVH252009-3R3M in a high-temperature environment?
  The CVH252009-3R3M is rated for operation up to 125°C. However, the inductor's characteristics may change at high temperatures, so it's essential to derate the component and consider the temperature coefficient of inductance (TCI) when designing for high-temperature applications.
• How do I ensure the reliability of the CVH252009-3R3M in a high-vibration environment?
  To ensure the reliability of the CVH252009-3R3M in a high-vibration environment, use a secure mounting method, such as soldering or adhesive bonding, and consider using a vibration-dampening material or a shock-absorbing mount.
• Can I use the CVH252009-3R3M in a high-current application?
  The CVH252009-3R3M is rated for a maximum current of 2.5 A. To ensure reliable operation, derate the current handling based on the ambient temperature and the inductor's temperature rise, and consider using a heat sink or a thermal interface material.
