CTX33-3-R - Eaton

CTX33-3-R Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and land pattern for optimal performance?
  Coiltronics recommends a PCB layout with a minimum of 1.5 mm clearance around the inductor and a land pattern with a 1.1 mm diameter pad for the terminals. A symmetrical layout and a solid ground plane are also recommended to minimize electromagnetic interference.
• How does the CTX33-3-R inductor perform in high-temperature environments?
  The CTX33-3-R is rated for operation up to 125°C, but its inductance and Q factor may degrade at higher temperatures. Coiltronics recommends derating the inductor's current rating by 1.5% per degree Celsius above 80°C to ensure reliable operation.
• What is the self-resonant frequency (SRF) of the CTX33-3-R inductor?
  The SRF of the CTX33-3-R is not explicitly stated in the datasheet, but it can be estimated to be around 150-200 MHz based on the inductor's physical characteristics and Coiltronics' typical SRF ranges for similar products.
• Can the CTX33-3-R inductor be used in high-vibration or high-shock environments?
  The CTX33-3-R is designed to meet the vibration and shock requirements of IEC 60068-2-6 and IEC 60068-2-27, respectively. However, it's recommended to consult with Coiltronics or perform additional testing to ensure the inductor meets the specific requirements of your application.
• Are there any specific soldering or assembly recommendations for the CTX33-3-R inductor?
  Coiltronics recommends using a soldering temperature of 260°C (max) and a soldering time of 3 seconds (max) to prevent damage to the inductor. A soldering iron with a temperature-controlled tip is recommended, and the inductor should be handled by the terminals to prevent mechanical stress.
