GRM1885C2E100JW07D - Murata Electronics

GRM1885C2E100JW07D Frequently Asked Questions (FAQs)

• What is the recommended land pattern for this capacitor?
  Murata recommends a land pattern with a pad size of 2.5mm x 1.25mm, with a non-solder mask defined (NSMD) pad shape. The land pattern should also have a clearance of at least 0.2mm around the pad to ensure reliable soldering.
• How do I handle the capacitor's moisture sensitivity?
  The GRM1885C2E100JW07D is a moisture-sensitive device. To prevent moisture absorption, it's recommended to store the capacitors in a dry environment (less than 30% RH) and to bake them at 125°C for 24 hours before soldering. Additionally, use a nitrogen-filled packaging or a dry pack to minimize exposure to moisture during transportation and storage.
• What is the maximum voltage derating for this capacitor?
  Murata recommends derating the voltage by 10% to 20% to ensure reliable operation. For the GRM1885C2E100JW07D, the maximum voltage rating is 100V, so the derated voltage would be 80V to 90V.
• Can I use this capacitor in a high-frequency application?
  The GRM1885C2E100JW07D is a general-purpose ceramic capacitor, and its frequency characteristics are suitable for most applications up to 100 MHz. However, for high-frequency applications above 100 MHz, Murata recommends using a capacitor with a higher self-resonant frequency, such as the GRM155 series.
• How do I ensure the capacitor's reliability in a high-temperature environment?
  To ensure reliability in high-temperature environments, it's essential to follow Murata's recommended temperature derating guidelines. For the GRM1885C2E100JW07D, the maximum operating temperature is 125°C. Derate the voltage by 1.25% per °C above 85°C to prevent thermal runaway and ensure reliable operation.
