注意事项 PRECAUTIONS

Cooling requirement: Must use conduction cooling (e.g., heat sink attached to aluminum base plate); follow derating curves based on base plate temperature

1 Mounting guidelines: Leave space between multiple modules for ventilation; avoid routing input/output patterns under the module to reduce noise; use copper pattern on PCB as shield (connect to CASE pin or mounting hole)

2 Pin stress: Do not apply excessive force to pins (e.g., +VOUT/-VOUT ≤39.2N, other pins ≤19.6N); avoid bending/pulling leads

3 Soldering limits: Flow soldering at ≤260°C for ≤15s; soldering iron (26W) at ≤450°C for ≤5s

4 Safety: Read instruction manual and safety documents before operation; minimize temperature fluctuations to extend thermal fatigue life

5 Mounting torque: Screwing torque for mounting holes should not exceed 0.49N·m (5kgf·cm)
