1812L020 - LITTELFUSE

1812L020 Frequently Asked Questions (FAQs)

• What is the recommended land pattern for the 1812L020?
  The recommended land pattern for the 1812L020 is a rectangular pad with a size of 1.8mm x 1.2mm, with a 0.5mm x 0.5mm thermal pad in the center. The pad should be solder-mask defined and have a non-solder-mask-defined (NSMD) pad for the thermal pad.
• Can I use the 1812L020 in a high-temperature application?
  The 1812L020 is rated for operation up to 150°C, but it's recommended to derate the current rating by 1.5% per degree Celsius above 125°C. For high-temperature applications, it's recommended to consult with Littelfuse Inc or a thermal expert to ensure the device can operate safely and reliably.
• How do I handle the 1812L020 during assembly and rework?
  The 1812L020 is a sensitive device and requires careful handling during assembly and rework. It's recommended to use a no-clean or low-residue flux, and to avoid exposing the device to excessive heat, moisture, or mechanical stress. Rework should be done using a low-temperature soldering iron and a gentle touch to avoid damaging the device.
• What is the recommended soldering profile for the 1812L020?
  The recommended soldering profile for the 1812L020 is a peak temperature of 240°C to 250°C, with a dwell time of 30 seconds to 60 seconds above 217°C. The soldering process should be done in a nitrogen atmosphere to minimize oxidation and ensure reliable joints.
• Can I use the 1812L020 in a high-vibration or high-shock application?
  The 1812L020 is designed to withstand normal vibration and shock, but it's recommended to consult with Littelfuse Inc or a mechanical expert to ensure the device can operate safely and reliably in high-vibration or high-shock applications. Additional mechanical support or potting may be required to ensure the device's reliability.
