GRM022R71A471KA01L - Murata Electronics

GRM022R71A471KA01L Frequently Asked Questions (FAQs)

• What is the recommended land pattern for this capacitor?
  The recommended land pattern for the GRM022R71A471KA01L can be found in the Murata Land Pattern Recommendation document, which provides guidelines for pad size, shape, and spacing to ensure reliable soldering and minimize defects.
• How does the capacitor perform in high-frequency applications?
  The GRM022R71A471KA01L is a general-purpose ceramic capacitor, but it can still be used in high-frequency applications up to 1 GHz. However, its performance may degrade above 100 MHz due to ESL and ESR effects. For high-frequency applications, Murata recommends using their high-frequency ceramic capacitors, such as the GRM155 series.
• Is the capacitor suitable for automotive applications?
  The GRM022R71A471KA01L is not AEC-Q200 qualified, which is a standard for automotive components. However, Murata offers other ceramic capacitors that meet the AEC-Q200 standard, such as the GRM155R71A471KA01D. It's recommended to check the specific requirements of the automotive application and consult with Murata's technical support team.
• What is the maximum operating temperature range for this capacitor?
  The GRM022R71A471KA01L has a maximum operating temperature range of -55°C to 125°C, as specified in the datasheet. However, the capacitor's performance and reliability may degrade if operated at the extreme ends of this range for extended periods.
• Can I use this capacitor in a flex circuit or flexible PCB?
  The GRM022R71A471KA01L is a rigid ceramic capacitor, and its use in flex circuits or flexible PCBs is not recommended. The capacitor's terminals may not withstand the flexing and bending stresses, which can lead to mechanical failure or electrical shorts. Murata offers flexible ceramic capacitors, such as the FX series, specifically designed for use in flex circuits and flexible PCBs.
