GRM022R71A101KA01L - Murata Electronics

GRM022R71A101KA01L Frequently Asked Questions (FAQs)

• What is the recommended land pattern for this capacitor?
  Murata provides a recommended land pattern for the GRM022R71A101KA01L in their capacitor catalog or on their website. The recommended land pattern is typically a rectangular pad with a size of 0.5mm x 0.5mm, with a solder mask clearance of 0.1mm.
• How do I handle the capacitor's moisture sensitivity?
  The GRM022R71A101KA01L is a moisture-sensitive device (MSD). To handle it, follow the guidelines in IPC/JEDEC J-STD-033C, which recommends storing the components in a dry environment, using a dry pack or airtight container, and baking the components before reflow soldering if they have been exposed to high humidity.
• What is the capacitor's equivalent series resistance (ESR)?
  The ESR of the GRM022R71A101KA01L is not explicitly stated in the datasheet, but it can be estimated based on the capacitor's impedance characteristics. According to Murata's application notes, the ESR of a similar capacitor is around 0.1 ohms at 100 kHz. However, it's recommended to consult with Murata's technical support or perform measurements to determine the ESR for a specific application.
• Can I use this capacitor in a high-vibration environment?
  The GRM022R71A101KA01L is a ceramic capacitor, which is generally suitable for use in high-vibration environments. However, it's essential to ensure that the capacitor is properly mounted and secured to the PCB to prevent mechanical stress and damage. Murata provides guidelines for capacitor mounting and vibration testing in their application notes.
• How does the capacitor's capacitance change with temperature?
  The GRM022R71A101KA01L has a capacitance tolerance of ±10% at 25°C. The capacitance may change with temperature, following a characteristic curve that can be found in Murata's application notes or capacitor catalog. The capacitance typically decreases as the temperature increases, with a temperature coefficient of capacitance (TCC) of around -55 ppm/°C.
