1 Telecom equipment (base stations, communication routers) needing stable DC power conversion

2 Industrial automation systems (PLCs, motor drives) requiring efficient power management

3 Network devices and data centers using compact, high-reliability power modules

4 Embedded systems with remote power control and sensing needs

5 Applications preferring conduction cooling for low noise and space efficiency

6 Systems compliant with international safety/environmental regulations (CE, RoHS, UL)

7 Harsh environments (wide temp range, vibration-prone settings)

1 Use conduction cooling (attach heat sink to aluminum base plate) and follow derating curves

2 Leave ventilation space when mounting multiple modules to maintain base plate temp

3 Avoid routing DC input/output patterns under the module to reduce noise

4 Add copper shield pattern on PCB connected to CASE pin/mounting hole for noise reduction

5 Do not apply excessive stress to pins (max: +VOUT/-VOUT <39.2N; others <19.6N)

6 Use 3.5mm diameter PCB mounting holes; fix module with screws before soldering pins

7 Follow soldering specs: flow soldering at260°C (≤15s), soldering iron (26W) at450°C (≤5s)

8 For CBS350/450 with -T option, connect mounting hole to grounding capacitor CY

9 Avoid operating in derating curve hatched areas to prevent excessive ripple/noise

10 Minimize temperature fluctuations to extend thermal fatigue life

11 Read official instruction manual and safety guidelines before use
