RLB0608-3R3ML - Bourns

RLB0608-3R3ML Frequently Asked Questions (FAQs)

• What is the recommended land pattern for this inductor?
  The recommended land pattern for the RLB0608-3R3ML inductor is a rectangular pad with a size of 1.2 mm x 1.4 mm, with a non-solder mask defined (NSMD) pad shape. This can be found in the Bourns application note 'Surface Mount Inductor Land Pattern' (document number 3281).
• How do I handle the inductor's thermal derating?
  The RLB0608-3R3ML inductor has a temperature derating curve specified in the datasheet. To handle thermal derating, you should ensure that the inductor's operating temperature is within the specified range, and that the current through the inductor is reduced accordingly based on the derating curve. You can also consider using a heat sink or thermal pad to improve heat dissipation.
• What is the inductor's self-resonant frequency (SRF)?
  The self-resonant frequency (SRF) of the RLB0608-3R3ML inductor is not explicitly specified in the datasheet. However, according to Bourns' application note 'Inductor Self-Resonance' (document number 3282), the SRF can be estimated using the inductor's inductance value and the parasitic capacitance. For the RLB0608-3R3ML, the estimated SRF is around 150-200 MHz.
• Can I use this inductor in a high-frequency application?
  The RLB0608-3R3ML inductor is designed for general-purpose use and is suitable for frequencies up to 100 MHz. However, for high-frequency applications above 100 MHz, you may need to consider a different inductor with a higher SRF and lower parasitic capacitance. Bourns offers other inductor series, such as the SRN series, that are specifically designed for high-frequency applications.
• How do I ensure the inductor's reliability in a high-reliability application?
  To ensure the reliability of the RLB0608-3R3ML inductor in a high-reliability application, you should follow proper storage, handling, and assembly procedures. Additionally, you should consider using a inductor with a higher temperature rating, such as the RLB0608-3R3MH, which is designed for high-reliability applications. You should also perform thorough testing and validation of the inductor in your specific application.
