KRM55TR72J474MH01L - Murata Electronics

KRM55TR72J474MH01L Frequently Asked Questions (FAQs)

• What is the recommended land pattern for this capacitor?
  The recommended land pattern for the KRM55TR72J474MH01L capacitor can be found in the Murata Land Pattern document, which provides detailed information on the recommended pad layout and dimensions for optimal mounting and soldering.
• How do I handle the capacitor during assembly to prevent damage?
  To prevent damage, handle the capacitor by the body, avoiding touching the terminals. Use an anti-static wrist strap or mat to prevent electrostatic discharge. Avoid bending or flexing the capacitor, and do not apply excessive force during assembly.
• What is the maximum allowable voltage derating for this capacitor?
  The maximum allowable voltage derating for the KRM55TR72J474MH01L capacitor is 80% of the rated voltage. This means that if the capacitor is rated for 50V, the maximum allowable voltage derating would be 40V.
• Can I use this capacitor in a high-temperature environment?
  The KRM55TR72J474MH01L capacitor is rated for operation up to 125°C. However, the capacitance and ESR may vary with temperature. Consult the datasheet and Murata's application notes for guidance on using this capacitor in high-temperature environments.
• How do I determine the equivalent series resistance (ESR) of this capacitor?
  The ESR of the KRM55TR72J474MH01L capacitor can be determined by measuring the impedance of the capacitor at high frequency (e.g., 100 kHz) using an impedance analyzer or a network analyzer. The ESR is typically specified in the datasheet, but it can also be calculated using the measured impedance data.
