11R223C - Murata Electronics

11R223C Frequently Asked Questions (FAQs)

• What is the recommended land pattern for the 11R223C?
  Murata recommends a land pattern with a pad size of 2.5mm x 1.3mm, with a non-solder mask defined (NSMD) pad shape, and a minimum clearance of 0.2mm between the pad and the solder mask.
• How do I handle the 11R223C's sensitivity to moisture?
  To prevent moisture-related issues, store the capacitors in a dry environment (less than 30% RH) and avoid exposing them to high humidity or temperature fluctuations during assembly and storage. Use a moisture barrier bag or dry pack to store the components.
• What is the maximum allowable voltage derating for the 11R223C?
  Murata recommends derating the voltage by 10% to 20% to ensure reliable operation and prevent premature failure. For example, if the rated voltage is 50V, the maximum allowable voltage would be 40V to 45V.
• Can I use the 11R223C in high-frequency applications?
  Yes, the 11R223C is suitable for high-frequency applications up to 1 GHz. However, it's essential to consider the capacitor's self-resonant frequency (SRF) and ensure that the operating frequency is below the SRF to avoid resonance and potential performance issues.
• How do I ensure the 11R223C's reliability in high-temperature environments?
  To ensure reliability in high-temperature environments, follow Murata's recommended temperature derating guidelines, which typically involve reducing the voltage rating by 1.25% to 2.5% per degree Celsius above 85°C. Additionally, consider using a capacitor with a higher temperature rating, such as the 11R223C's 125°C variant.
