GCM31CR91H474KA37K - Murata Electronics

GCM31CR91H474KA37K Frequently Asked Questions (FAQs)

• What is the recommended land pattern for this capacitor?
  The recommended land pattern for the GCM31CR91H474KA37K can be found in Murata's Capacitor Land Pattern document, which provides guidelines for PCB layout and pad design to ensure reliable mounting and soldering.
• How does the capacitor's ESR affect its performance in high-frequency circuits?
  The Equivalent Series Resistance (ESR) of the GCM31CR91H474KA37K is an important parameter in high-frequency circuits, as it affects the capacitor's impedance and energy losses. A lower ESR generally results in better high-frequency performance, and Murata's datasheet provides ESR values for this capacitor.
• Is the GCM31CR91H474KA37K suitable for use in automotive applications?
  While the GCM31CR91H474KA37K is a high-reliability capacitor, it is not specifically designed for automotive applications. Murata offers other capacitor series, such as the GRM series, that are designed to meet the stringent requirements of the automotive industry.
• Can I use the GCM31CR91H474KA37K in a high-temperature environment?
  The GCM31CR91H474KA37K has a maximum operating temperature of 125°C, but its capacitance and ESR may change significantly at high temperatures. Murata recommends derating the capacitor's voltage and current ratings at high temperatures, and consulting the datasheet for more information.
• How does the capacitor's voltage rating affect its lifespan?
  The voltage rating of the GCM31CR91H474KA37K affects its lifespan, as excessive voltage can cause dielectric breakdown and reduce the capacitor's lifespan. Operating the capacitor at a voltage below its rated value can help extend its lifespan, and Murata recommends following the datasheet's guidelines for voltage derating.
