GRM155R71E622KA01D Frequently Asked Questions (FAQs)

• What is the recommended land pattern for this capacitor?
  Murata provides a recommended land pattern for the GRM155R71E622KA01D capacitor in their documentation. The recommended land pattern is a rectangular pad with a size of 1.3mm x 0.8mm, with a solder mask clearance of 0.1mm. It's essential to follow this land pattern to ensure reliable soldering and to prevent defects.
• How does the capacitor's ESR affect its performance in my circuit?
  The Equivalent Series Resistance (ESR) of the GRM155R71E622KA01D capacitor is 0.022 ohms. A low ESR is essential for high-frequency circuits, as it reduces energy losses and improves the capacitor's ability to filter out noise. In your circuit, a low ESR can help to reduce voltage ripple, improve power supply efficiency, and reduce electromagnetic interference (EMI).
• Is the GRM155R71E622KA01D capacitor suitable for high-temperature applications?
  The GRM155R71E622KA01D capacitor has a maximum operating temperature of 125°C, making it suitable for high-temperature applications. However, it's essential to note that the capacitor's characteristics, such as capacitance and ESR, may change at high temperatures. Be sure to check the datasheet for temperature derating information and to consult with Murata's application notes for high-temperature applications.
• How do I handle the capacitor's moisture sensitivity during storage and assembly?
  The GRM155R71E622KA01D capacitor is a moisture-sensitive device (MSD) and requires special handling during storage and assembly. It's essential to store the capacitors in a dry environment, with a relative humidity of less than 30%. During assembly, follow Murata's recommended procedures for handling MSDs, including baking the capacitors before assembly and using a nitrogen-filled environment to prevent moisture absorption.
• What is the recommended soldering profile for this capacitor?
  Murata recommends a soldering profile with a peak temperature of 260°C, a dwell time of 10-30 seconds, and a cooling rate of 2-4°C/second. It's essential to follow this profile to prevent damage to the capacitor and to ensure reliable solder joints. Be sure to consult with Murata's application notes for more information on soldering profiles and techniques.
