The maximum operating temperature range for the PTH12010WAS is -40°C to 125°C, as specified in the datasheet. However, it's recommended to derate the output power above 85°C to ensure reliable operation.
The PTH12010WAS meets various safety standards, including UL60950-1, IEC60950-1, and EN60950-1. To ensure compliance, follow the recommended layout and component selection guidelines provided in the datasheet and application notes.
The recommended input capacitor value is 10uF to 22uF, with a voltage rating of 50V or higher. A low-ESR ceramic or film capacitor is recommended, such as the X5R or X7R dielectric type.
To optimize output voltage ripple and noise, use a combination of output capacitors with different values and types, such as ceramic, film, and electrolytic capacitors. The datasheet provides guidance on output capacitor selection and placement.
The maximum output current derating for the PTH12010WAS at high temperatures is 0.5A/°C above 85°C. This means that for every 1°C increase in temperature above 85°C, the maximum output current should be reduced by 0.5A.
