PRF18BG471QB1RB - Murata Electronics

PRF18BG471QB1RB Frequently Asked Questions (FAQs)

• What is the recommended land pattern for PRF18BG471QB1RB?
  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 recommended land pattern is available in the Murata Capacitor Land Pattern document.
• Can I use PRF18BG471QB1RB in a high-temperature environment?
  The PRF18BG471QB1RB is rated for operation up to 125°C, but its capacitance and ESR may degrade at high temperatures. For applications above 105°C, derating is recommended. Consult the datasheet and Murata's reliability handbook for more information.
• How do I handle the PRF18BG471QB1RB capacitor during PCB assembly?
  Handle the capacitor by the edges or the body, avoiding touching the terminals. Use a vacuum pick-up or tweezers to prevent damage. Avoid bending, flexing, or applying excessive force, which can cause internal damage or terminal breakage.
• Is the PRF18BG471QB1RB capacitor suitable for high-frequency applications?
  Yes, the PRF18BG471QB1RB is designed for high-frequency applications, with a self-resonant frequency of 10.5MHz. However, its performance may degrade at frequencies above 100MHz. Consult the datasheet and Murata's application notes for more information.
• Can I use PRF18BG471QB1RB in a humid or moist environment?
  The PRF18BG471QB1RB is not designed for use in humid or moist environments. It is recommended to use a conformal coating or potting compound to protect the capacitor from moisture. Consult Murata's reliability handbook for more information.
