GCM188R72A103MA37D - Murata Electronics

GCM188R72A103MA37D Frequently Asked Questions (FAQs)

• What is the recommended land pattern for this capacitor?
  The recommended land pattern for the GCM188R72A103MA37D 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 GCM188R72A103MA37D is relatively low, which makes it suitable for high-frequency applications. However, it's essential to consider the ESR value when designing the circuit to ensure that it doesn't affect the overall performance. A lower ESR value generally results in less energy loss and improved circuit efficiency.
• Is the capacitor suitable for use in high-temperature environments?
  The GCM188R72A103MA37D has a rated operating temperature range of -55°C to +125°C, making it suitable for use in high-temperature environments. However, it's essential to consider the derating curves and temperature coefficients to ensure that the capacitor operates within its specified limits.
• What is the recommended soldering profile for this capacitor?
  Murata recommends a soldering profile with a peak temperature of 260°C and a dwell time of 10-30 seconds. It's essential to follow the recommended soldering profile to prevent damage to the capacitor and ensure reliable solder joints.
• How does the capacitor's capacitance value change with voltage?
  The capacitance value of the GCM188R72A103MA37D may vary with voltage due to the ceramic material's characteristics. The datasheet provides a capacitance vs. voltage curve, which shows that the capacitance value decreases as the voltage increases. It's essential to consider this characteristic when designing the circuit to ensure that the capacitor operates within its specified limits.
