RCER71H474K1DBH03A - Murata Electronics

RCER71H474K1DBH03A Frequently Asked Questions (FAQs)

• What is the recommended land pattern for the RCER71H474K1DBH03A?
  Murata recommends a land pattern with a pad size of 2.5mm x 1.25mm, with a non-solder mask defined (NSMD) pad shape, and a minimum clearance of 0.2mm between the pad and the solder mask.
• How do I handle the thermal considerations for this chip resistor?
  To ensure reliable operation, it's essential to consider thermal management. The RCER71H474K1DBH03A has a thermal resistance of 250°C/W. Ensure good thermal conduction by using a thermal pad or via, and keep the ambient temperature below 70°C.
• What is the recommended soldering profile for the RCER71H474K1DBH03A?
  Murata recommends a soldering profile with a peak temperature of 260°C, a dwell time above 240°C of 30-60 seconds, and a cooling rate of 3-5°C/s. Avoid exceeding 280°C to prevent damage to the component.
• Can I use the RCER71H474K1DBH03A in a high-frequency application?
  While the RCER71H474K1DBH03A is a general-purpose chip resistor, it's not optimized for high-frequency applications. For frequencies above 100 MHz, consider using a high-frequency resistor with a lower ESL (equivalent series inductance) and ESR (equivalent series resistance).
• How do I ensure the reliability of the RCER71H474K1DBH03A in a humid environment?
  To ensure reliability in humid environments, follow Murata's recommended storage and handling guidelines. Store the components in a dry, cool place, and avoid exposing them to moisture or condensation. Consider using a moisture-resistant coating or conformal coating for added protection.
