RECOM recommends a PCB layout with a large copper area connected to the module's thermal pad to ensure good heat dissipation. A minimum of 2 oz copper thickness is recommended.
RECOM recommends adding external bypass capacitors (e.g., 10uF ceramic capacitors) between the input pins and the module's input capacitors to ensure proper bypassing and noise reduction.
The RNM-3.305S/P can tolerate an input voltage deviation of ±10% of the nominal input voltage without affecting its performance or reliability.
While the module is rated for operation up to 80°C, RECOM recommends derating the output power by 2.5% per degree above 60°C to ensure reliable operation in high-temperature environments.
RECOM recommends following proper PCB layout and grounding practices, using a metal enclosure, and adding external EMI filters if necessary to ensure EMC compliance.
