CDRH2D18/LDNP-470NC - Sumida

CDRH2D18/LDNP-470NC Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  A symmetrical layout with a solid ground plane and minimal signal trace length is recommended. Keep the component away from high-frequency noise sources and ensure good thermal dissipation.
• How do I ensure reliable soldering and avoid damage during reflow?
  Use a soldering iron with a temperature range of 220-250°C. Apply a small amount of solder paste and ensure the component is properly aligned. Avoid overheating or applying excessive force during reflow.
• What is the maximum allowed voltage drop across the inductor?
  The maximum allowed voltage drop is 1.5V. Exceeding this may cause overheating, reduced lifespan, or even damage to the component.
• Can I use this inductor in a high-temperature environment?
  The CDRH2D18/LDNP-470NC is rated for operation up to 125°C. However, derating is recommended for temperatures above 85°C to ensure reliability and prevent thermal runaway.
• How do I calculate the inductor's self-resonant frequency?
  The self-resonant frequency can be estimated using the formula: f_res = 1 / (2 * π * sqrt(L * C)), where L is the inductance and C is the equivalent capacitance. Consult the datasheet for specific values.
