注意事项 PRECAUTIONS

1 Thermal management: Utilize top/bottom surface cooling or lead cooling to maintain internal temp within -40°C (T-grade) or -55°C (M-grade) to 125°C; refer to thermal resistance values for proper heat dissipation design

2 Input/output filter: Do not exceed secondary external capacitance limit (1000µF); for higher energy storage, use primary capacitance scaled by K² (1/1024 for K=1/32) to reduce component size

3 Array current sharing: Use symmetric PCB layout, common copper planes, and input filters to prevent circulating currents in parallel arrays

4 Fuse selection: Implement system-level fusing with current rating > module max current, voltage rating > max input voltage, and consider ambient temp and melting I²t

5 Reverse operation: Only use qualified reversible models (0R/0P); start with primary voltage > VPRI_UVLO+_R before continuous reverse operation

6 PMBus usage: The PMBus-enabled module cannot operate alone; must be paired with Vicor Digital Isolator (e.g., I13TL1A0) and Digital Supervisor (e.g., D44TL1A0)

7 Avoid over-spec operation: Do not expose the module to voltage/current beyond its rated range; internal protection functions (OVLO/UVLO) are for normal operation, not transient overstress

8 Storage/handling: Store in dry conditions; avoid damaging lead finish (Ni/Pd/Au layers) during assembly
