GRM1553C1H2R2BA01D - Murata Electronics

GRM1553C1H2R2BA01D Frequently Asked Questions (FAQs)

• What is the recommended land pattern for this capacitor?
  The recommended land pattern for the GRM1553C1H2R2BA01D can be found in Murata's Capacitor Land Pattern document, which provides guidelines for pad size, spacing, and shape to ensure reliable soldering and minimize defects.
• How does the capacitor's self-resonant frequency affect its performance?
  The self-resonant frequency of the GRM1553C1H2R2BA01D is around 100 MHz, which means it can resonate and cause impedance peaks at this frequency. This can affect the capacitor's performance in high-frequency circuits, and engineers should consider this when designing their circuits.
• What is the maximum voltage derating for this capacitor?
  Murata recommends derating the maximum voltage of the GRM1553C1H2R2BA01D by 10% to ensure reliable operation. For example, if the capacitor is rated for 50V, the maximum operating voltage should be limited to 45V.
• How does the capacitor's temperature coefficient affect its capacitance?
  The GRM1553C1H2R2BA01D has a temperature coefficient of ±30 ppm/°C, which means its capacitance can vary by up to 30 ppm for every degree Celsius change in temperature. This can affect the capacitor's performance in temperature-sensitive applications.
• What is the recommended reflow soldering profile for this capacitor?
  Murata recommends a reflow soldering profile with a peak temperature of 260°C and a dwell time of 30-60 seconds to ensure reliable soldering of the GRM1553C1H2R2BA01D. The exact profile may vary depending on the specific application and PCB design.
