4 Networking devices: Routers, switches, and communication hubs requiring compact designs

5 Mission-critical civilian applications: Emergency response systems, traffic management equipment

6 Space-constrained designs: Portable test instruments and compact embedded systems

注意事项 PRECAUTIONS

1 Thermal management: Follow output current derating curves and ensure adequate cooling to prevent overheating

2 Soldering guidelines: Adhere to SnPb/Pb-free reflow profiles; avoid peak product temperature exceeding +225°C (SnPb) or +260°C (Pb-free)

3 Remote sense usage: Connect to load terminals for accurate regulation; do not leave open unnecessarily

4 Input voltage limits: Do not exceed 36-75Vdc continuous input or 100Vdc transient

5 Protection features: Non-latching overvoltage/overtemperature protection auto-resumes after fault removal

6 Safety compliance: Final product must meet IEC/EN/UL60950 standards and clearance requirements

7 External components: Add input capacitors if source inductance >10µH; use decoupling capacitors near dynamic loads

8 Remote control setup: Verify logic type (positive/negative) and ensure RC pin voltage difference <1V for shut-off
