CUI recommends a PCB layout with a solid ground plane and thermal vias to dissipate heat. A minimum of 2oz copper thickness is recommended. Additionally, a thermal interface material (TIM) with a thermal conductivity of 1W/m-K or higher is suggested between the module and the heat sink.
To ensure reliability and longevity, operate the module within the recommended temperature range (–40°C to +85°C). Implement proper thermal management, and ensure the module is not exposed to moisture, vibration, or physical stress. Regularly inspect the module for signs of wear or damage.
The PQS075-S5-S3-S is designed to meet CISPR 22 Class B emissions standards. To minimize EMI and RFI, use a shielded enclosure, keep cables away from noise sources, and use EMI filters or common-mode chokes as needed. Ensure the module is properly grounded and follow good PCB layout practices.
Yes, the PQS075-S5-S3-S can be used in redundant or parallel configurations. However, it's essential to follow CUI's guidelines for paralleling or redundancy to ensure proper operation and to avoid damage to the modules. Consult with CUI's application engineers for specific guidance.
The PQS075-S5-S3-S is certified to UL 60950-1, EN 60950-1, and IEC 60950-1 safety standards. It also meets the requirements of RoHS, REACH, and WEEE directives. Consult the datasheet or CUI's website for the latest certification information.
