LQM21PN1R0NGCD - Murata Electronics

LQM21PN1R0NGCD Frequently Asked Questions (FAQs)

• What is the recommended land pattern for LQM21PN1R0NGCD?
  The recommended land pattern for LQM21PN1R0NGCD is a rectangular pad with a size of 1.4mm x 1.2mm, with a non-solder mask defined (NSMD) pad shape. This is to ensure proper soldering and to prevent solder bridging.
• Can I use the LQM21PN1R0NGCD in a high-temperature environment?
  The LQM21PN1R0NGCD is rated for operation up to 125°C, but it's recommended to derate the current rating according to the temperature derating curve provided in the datasheet. It's also important to ensure that the component is properly cooled to prevent overheating.
• How do I handle the LQM21PN1R0NGCD during PCB assembly to prevent damage?
  To prevent damage, handle the LQM21PN1R0NGCD by the edges, avoid touching the component's surface, and use an anti-static wrist strap or mat. Also, ensure that the PCB is properly cleaned and dried before assembly to prevent moisture damage.
• What is the equivalent series resistance (ESR) of the LQM21PN1R0NGCD?
  The ESR of the LQM21PN1R0NGCD is not explicitly stated in the datasheet, but it can be estimated to be around 0.1-0.2 ohms based on the component's design and materials. However, it's recommended to consult with Murata's application engineers or perform measurements to determine the exact ESR value for a specific application.
• Can I use the LQM21PN1R0NGCD in a high-frequency application?
  The LQM21PN1R0NGCD is designed for high-frequency applications up to 1 GHz, but it's essential to consider the component's self-resonant frequency (SRF) and ensure that it's not operated near the SRF to prevent unwanted resonances and losses.
