PWR163S-25-2R50JE - Bourns

PWR163S-25-2R50JE Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and land pattern for optimal performance?
  Bourns provides a recommended PCB layout and land pattern in their application notes and design guides. It's essential to follow these guidelines to ensure proper thermal management, reduce parasitic inductance, and optimize performance.
• How do I select the correct current rating for my application?
  To select the correct current rating, consider the maximum current required by your load, as well as any potential inrush currents or surges. Also, ensure the resistor's power rating is sufficient to handle the expected power dissipation.
• What is the tolerance on the resistance value, and how does it affect my design?
  The PWR163S-25-2R50JE has a resistance tolerance of ±1%. This means the actual resistance value may vary by up to 1% from the nominal value. Ensure your design can accommodate this tolerance to avoid any potential issues.
• How does the resistor's temperature coefficient affect my design?
  The temperature coefficient of resistance (TCR) specifies how much the resistance value changes with temperature. For the PWR163S-25-2R50JE, the TCR is ±50 ppm/°C. This means the resistance value may change by up to 0.005% per degree Celsius. Consider this when designing for temperature-sensitive applications.
• Is the resistor suitable for high-frequency applications?
  While the PWR163S-25-2R50JE is a power resistor, it's not optimized for high-frequency applications. If you need a resistor for high-frequency use, consider Bourns' high-frequency resistor series or consult with their application engineers for guidance.
