API Delevan recommends a symmetrical PCB layout with a minimum of 50 mils (1.27 mm) spacing between the transformer and other components. A recommended land pattern is available upon request from API Delevan's technical support team.
API Delevan recommends a minimum creepage distance of 3.2 mm (0.125 in) between the primary and secondary windings, and a minimum insulation thickness of 0.5 mm (0.02 in) for high-voltage applications. Additionally, ensure that the PCB material meets the required insulation and tracking resistance standards.
The HCTR-443 is rated for operation from -40°C to +125°C, with a maximum storage temperature range of -40°C to +150°C. However, derating may be necessary for high-temperature applications, and API Delevan recommends consulting their technical support team for specific guidance.
API Delevan recommends using proper shielding, grounding, and filtering techniques to minimize EMI and ensure EMC compliance. Additionally, ensure that the transformer is properly decoupled from the PCB and other components, and consider using EMI-absorbing materials or shielding cans if necessary.
API Delevan recommends performing electrical testing, including hipot and insulation resistance tests, as well as environmental testing, such as temperature cycling and vibration testing, to ensure the transformer meets the required specifications and standards. Consult API Delevan's technical support team for specific testing and validation procedures.
