19R225C - Murata Electronics

19R225C Frequently Asked Questions (FAQs)

• What is the recommended land pattern for the 19R225C?
  Murata recommends a land pattern with a pad size of 2.5mm x 1.25mm, with a spacing of 0.5mm between pads. The land pattern should be designed to minimize thermal resistance and ensure good solderability.
• How does the 19R225C capacitor handle high-frequency noise?
  The 19R225C is designed to handle high-frequency noise due to its low equivalent series resistance (ESR) and high self-resonant frequency (SRF). The capacitor's internal construction and materials are optimized to minimize parasitic inductance and capacitance, making it suitable for high-frequency applications.
• Is the 19R225C capacitor suitable for automotive applications?
  Yes, the 19R225C is AEC-Q200 qualified, which means it meets the stringent requirements for automotive applications. It can operate in temperatures ranging from -40°C to 125°C, making it suitable for use in automotive systems.
• What is the maximum ripple current rating for the 19R225C?
  The maximum ripple current rating for the 19R225C is 1.5A RMS at 100kHz, with a temperature derating of 0.5A RMS per 10°C above 85°C. It's essential to ensure that the capacitor is operated within its specified ripple current rating to prevent overheating and premature failure.
• Can the 19R225C be used in high-voltage applications?
  The 19R225C has a rated voltage of 50V, but it can be used in high-voltage applications with proper derating. Murata recommends derating the capacitor by 10% for every 10°C above 85°C to ensure reliable operation. However, it's essential to consult with Murata's application engineers or a qualified design expert to determine the suitability of the capacitor for specific high-voltage applications.
