KC355LD7LQ474KV01L - Murata Electronics

KC355LD7LQ474KV01L 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 spacing of 0.5mm between pads. The land pattern should be designed to minimize thermal resistance and ensure good solderability.
• How does the capacitor perform in high-frequency applications?
  The KC355LD7LQ474KV01L is a general-purpose capacitor suitable for high-frequency applications up to 100 MHz. However, its performance may degrade above 100 MHz due to internal inductance and resistance. For high-frequency applications above 100 MHz, Murata recommends using specialized capacitors designed for high-frequency use.
• Is the capacitor suitable for use in high-temperature environments?
  The KC355LD7LQ474KV01L has a maximum operating temperature of 125°C. While it can withstand high temperatures, its capacitance and ESR may change significantly above 85°C. For high-temperature applications, Murata recommends using capacitors with a higher temperature rating, such as the KC series with a 150°C rating.
• What is the recommended soldering profile for this capacitor?
  Murata recommends a soldering profile with a peak temperature of 260°C, a dwell time of 10-30 seconds, and a cooling rate of 4°C/s or less. The soldering profile should be designed to minimize thermal shock and ensure good solder joint reliability.
• Are there any specific handling and storage precautions for this capacitor?
  Yes, the KC355LD7LQ474KV01L is a sensitive electronic component and requires proper handling and storage. It should be stored in a dry, cool place, away from direct sunlight and moisture. Handling should be done with anti-static precautions, such as using an anti-static wrist strap or mat, to prevent electrostatic discharge damage.
