The recommended land pattern for the CR0402-FX-6490GLF is a rectangular pad with a size of 0.5 mm x 0.3 mm, with a non-solder mask defined (NSMD) pad shape. This ensures proper soldering and minimizes the risk of solder bridging.
The CR0402-FX-6490GLF is rated for operation up to 150°C, but it's essential to consider the derating curve provided in the datasheet. For high-temperature applications, it's recommended to consult with Bourns' application engineers to ensure the component meets the specific requirements.
The CR0402-FX-6490GLF is designed to meet the requirements of IPC/JEDEC J-STD-020D, which includes testing for moisture sensitivity. However, it's crucial to follow proper storage and handling procedures to prevent moisture absorption. In high-humidity environments, it's recommended to use conformal coating or other protection methods to ensure reliability.
The recommended soldering profile for the CR0402-FX-6490GLF is a peak temperature of 260°C, with a dwell time of 10-30 seconds above 220°C. It's essential to follow the soldering profile recommended by Bourns to ensure reliable solder joints and prevent damage to the component.
The CR0402-FX-6490GLF is designed for general-purpose applications and may not be suitable for high-voltage surge applications. For such applications, it's recommended to consider Bourns' high-voltage chip resistors, such as the CHV series, which are specifically designed to handle high-voltage surges.
