MEJ2S1209SC - Murata Electronics

MEJ2S1209SC Frequently Asked Questions (FAQs)

• What is the recommended land pattern for the MEJ2S1209SC?
  Murata recommends a land pattern with a pad size of 1.3mm x 0.8mm, and a spacing of 0.5mm between pads. A detailed land pattern can be found in the Murata's recommended land pattern document.
• Can the MEJ2S1209SC be used in high-temperature applications?
  The MEJ2S1209SC is rated for operation up to 125°C, but it's recommended to derate the voltage and current ratings above 85°C. Consult the datasheet and Murata's application notes for more information on high-temperature usage.
• How do I ensure the reliability of the MEJ2S1209SC in humid environments?
  To ensure reliability in humid environments, it's recommended to follow Murata's guidelines for moisture sensitivity and reflow soldering. Additionally, consider using a conformal coating or potting compound to protect the device from moisture.
• What is the equivalent series resistance (ESR) of the MEJ2S1209SC?
  The ESR of the MEJ2S1209SC is not explicitly stated in the datasheet, but it can be estimated to be around 0.1-0.2 ohms based on Murata's typical ESR values for similar capacitors. However, it's recommended to consult with Murata's application engineers for more accurate information.
• Can the MEJ2S1209SC be used in high-vibration applications?
  The MEJ2S1209SC is designed to withstand vibrations up to 10G, but it's recommended to consult with Murata's application engineers to determine the suitability of the device for specific high-vibration applications.
