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 proper thermal performance and to prevent mechanical stress on the component.
The thermal pad on the bottom of the TC42X-2-105E is designed to be connected to a thermal plane on the PCB. It's recommended to use a thermal interface material (TIM) to fill the gap between the thermal pad and the PCB, and to ensure a solid connection to the thermal plane.
While the datasheet specifies an operating temperature range of -40°C to +125°C, it's essential to note that the device's performance and reliability may degrade at extreme temperatures. It's recommended to consult with Bourns' application engineers for specific guidance on operating temperature ranges for your application.
The TC42X-2-105E is designed to meet the requirements of various industries, including automotive and industrial. However, it's crucial to ensure that the component is properly secured to the PCB and that the PCB is designed to withstand the expected vibration levels. Consult with Bourns' application engineers for specific guidance on vibration testing and PCB design.
The current rating of the TC42X-2-105E depends on the specific application requirements. It's essential to consider factors such as the maximum current, surge current, and operating temperature. Consult with Bourns' application engineers or refer to their selection guides to determine the appropriate current rating for your application.
