UP1B-220-R - Eaton

UP1B-220-R Frequently Asked Questions (FAQs)

• What is the recommended PCB land pattern for the UP1B-220-R?
  The recommended PCB land pattern for the UP1B-220-R can be found in the Coiltronics application note AN-001, which provides detailed guidelines for PCB layout and design.
• How do I handle the thermal considerations for the UP1B-220-R?
  The UP1B-220-R has a maximum operating temperature of 125°C. To ensure reliable operation, it's essential to provide adequate thermal relief, such as using thermal vias and keeping the component away from heat sources.
• What is the self-resonant frequency (SRF) of the UP1B-220-R?
  The self-resonant frequency (SRF) of the UP1B-220-R is not explicitly stated in the datasheet. However, according to Coiltronics' application note AN-002, the SRF can be estimated using the inductor's inductance and capacitance values. For the UP1B-220-R, the estimated SRF is around 150-200 MHz.
• Can I use the UP1B-220-R in a high-frequency application?
  While the UP1B-220-R is suitable for high-frequency applications, its performance may degrade above 100 MHz due to the inductor's internal capacitance and resistance. It's recommended to consult with Coiltronics' application engineers or perform thorough simulations to ensure the inductor meets the specific application requirements.
• How do I select the correct UP1B-220-R variant for my application?
  Coiltronics offers various UP1B-220-R variants with different inductance values and tolerance ranges. To select the correct variant, consider factors such as the target inductance value, operating frequency, and desired tolerance. Consult the Coiltronics datasheet and application notes for guidance on selecting the appropriate variant.
