PTR901-2015K-A103 - Bourns

PTR901-2015K-A103 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 (AN16) and on their website. It's essential to follow these guidelines to ensure optimal performance, low thermal resistance, and minimal parasitic inductance.
• How do I select the correct resistor value and tolerance for my application?
  Bourns offers a resistor selection guide (AN13) that helps engineers choose the right resistor value and tolerance based on their specific application requirements, including power rating, operating temperature, and precision requirements.
• What is the maximum allowable voltage derating for this resistor?
  According to Bourns' application notes, the maximum allowable voltage derating for the PTR901-2015K-A103 is 80% of the rated voltage. Exceeding this derating may lead to premature failure or reduced reliability.
• Can I use this resistor in a high-frequency application?
  While the PTR901-2015K-A103 is a general-purpose resistor, it's not optimized for high-frequency applications. For high-frequency use, consider Bourns' high-frequency resistor series, such as the SRP or SRN series, which are designed to minimize parasitic inductance and capacitance.
• What is the expected lifespan and reliability of this resistor?
  Bourns' PTR901-2015K-A103 is a high-reliability resistor with a expected lifespan of 10,000 hours or more, depending on the operating conditions. The resistor is designed to meet or exceed industry standards for reliability, such as MIL-STD-202 and IEC 60115.
