CR2LS-100 - FUJI ELECTRIC

CR2LS-100 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and thermal management for optimal performance of the CR2LS-100?
  Fuji Electric recommends a 4-layer PCB with a dedicated ground plane and thermal vias to dissipate heat. A minimum of 1 oz copper thickness is recommended. Additionally, a heat sink with a thermal interface material (TIM) should be used to ensure efficient heat dissipation.
• How do I ensure the reliability and longevity of the CR2LS-100 in high-temperature applications?
  To ensure reliability and longevity, it's essential to operate the CR2LS-100 within its specified temperature range (-40°C to 150°C). Additionally, consider using a thermally conductive potting material, and ensure good airflow around the device. Regular cleaning and maintenance can also help prevent thermal issues.
• What are the recommended soldering conditions for the CR2LS-100?
  Fuji Electric recommends soldering the CR2LS-100 using a reflow soldering process with a peak temperature of 260°C (±5°C) and a dwell time of 30 seconds (±10 seconds). Hand soldering is not recommended due to the device's high power density.
• How do I protect the CR2LS-100 from electrical overstress (EOS) and electrostatic discharge (ESD)?
  To protect the CR2LS-100 from EOS and ESD, use a robust PCB design with adequate clearance and creepage distances. Implement ESD protection devices, such as TVS diodes or ESD arrays, and ensure that the device is handled and stored in an ESD-safe environment.
• What are the recommended storage and handling procedures for the CR2LS-100?
  Store the CR2LS-100 in its original packaging or an ESD-safe container, away from direct sunlight and moisture. Handle the device by the body, avoiding touching the leads or electrical contacts. Use an anti-static wrist strap or mat when handling the device.
