使用场景 APPLICATIONS

Distributed power supply systems in industrial electronics, where multiple subsystems need isolation from the main input power

1 Signal circuit applications such as normal/low-frequency artificial circuit conditions

2 Relay drive circuits requiring stable isolated power supply

3 Low-power electronic devices like sensor modules, control circuits needing DC-DC conversion

4 Harsh environment equipment (e.g., outdoor monitoring devices, industrial control systems) due to wide temperature adaptability

5 PCB-mounted projects that prioritize small component size and easy integration

注意事项 PRECAUTIONS

Operation under minimum load will not damage the converter but may not meet all specified performance parameters

1 Do not exceed the rated full load range (100% of maximum output) to ensure stable operation

2 The rated output load is applicable when input voltage is within ±10% tolerance and operating temperature is at normal range (25°C)

3 For full load operation, use high-frequency low-resistance electrolytic capacitors: Cin (1uF/50V) at input and Cout (1uF/50V) at output as per recommended test circuit

4 Storage temperature range should be between -55°C and +125°C; avoid storing in environments with humidity exceeding 95%

5 RoHS compliant models can withstand IR reflow peak temperature up to 240°C ±5°C; follow the specified reflow profile (ramp-up rate ≤15°C/sec, peak time 20-40 seconds, etc.) during soldering

6 Ensure proper insulation in applications to maintain the 1000VDC isolation voltage between input and output

7 Refer to detailed operation instructions in DC-DC Application Notes for ripple and noise testing (using "Xapabile" method)
