CTX10-1-R - Eaton

CTX10-1-R Frequently Asked Questions (FAQs)

• What is the recommended PCB land pattern for the CTX10-1-R?
  The recommended PCB land pattern for the CTX10-1-R is a rectangular pad with a size of 3.8mm x 2.5mm, with a 1.3mm diameter hole in the center for the pin. The pad should be solder-mask defined and have a non-solder-mask-defined area of 0.5mm around the pin.
• How do I handle the CTX10-1-R's thermal considerations?
  The CTX10-1-R has a maximum operating temperature of 125°C. To ensure reliable operation, it's essential to provide adequate thermal relief on the PCB, such as thermal vias or a thermal pad, to dissipate heat generated by the inductor. Additionally, avoid placing heat-sensitive components near the inductor.
• What is the CTX10-1-R's self-resonant frequency (SRF)?
  The self-resonant frequency (SRF) of the CTX10-1-R is approximately 150 MHz. This is the frequency at which the inductor's impedance peaks due to its internal capacitance and inductance. It's essential to consider the SRF when designing the circuit to avoid unwanted resonances.
• Can I use the CTX10-1-R in a high-vibration environment?
  The CTX10-1-R is designed to withstand moderate vibration levels. However, it's essential to ensure that the PCB is properly secured and the inductor is adequately soldered to the board to prevent mechanical stress. If the application involves extreme vibration, consider using a more ruggedized inductor or additional mechanical support.
• How do I determine the CTX10-1-R's saturation current?
  The saturation current of the CTX10-1-R can be determined by consulting the inductor's datasheet and application notes. The saturation current is typically defined as the current at which the inductor's inductance drops to 30% of its nominal value. For the CTX10-1-R, the saturation current is approximately 10 A.
