Bourns provides a recommended PCB layout and land pattern in their application note AN164, which can be found on their website. It's essential to follow these guidelines to ensure optimal performance, low thermal resistance, and minimal parasitic inductance.
The choice of TIM depends on the specific application and operating conditions. Bourns recommends using a TIM with a thermal conductivity of at least 1 W/m-K and a thickness of 0.05 mm to 0.15 mm. Some popular TIM options include thermal grease, thermal tape, or thermal pads.
According to Bourns, the PTR901-2015K-B202 can be derated up to 150% of the rated voltage for a maximum of 5 seconds. However, it's essential to consult the datasheet and application notes for specific derating guidelines and to ensure the resistor can handle the desired voltage and power dissipation.
To ensure proper soldering, follow the recommended soldering profile and guidelines provided in the datasheet and application notes. Use a solder with a melting point above 220°C, and avoid applying excessive heat or force, which can cause damage to the resistor or PCB.
The PTR901-2015K-B202 should be stored in a dry, cool place with a temperature range of -40°C to 125°C and humidity below 80%. Avoid exposing the resistor to corrosive substances, high temperatures, or physical stress during storage or operation.
