Adherence to these guidelines contributes to the high reliability of our products by restricting the maximum operating semiconductor junction temperatures to 125°C which is well below the component manufacturers’ maximum limits. Key to power derating curves: A Natural convection. B 150 linear feet per minute forced air flow. C 300 linear feet per minute forced air flow. D Maximum case temperature Heatsink options: Two heatsink kits are available for the NFC40: top mounted and side mounted. Each heatsink may be oriented parallel to or perpendicular to the direction of the pins, thus providing optimum flexibility for cooling requirements. Top mounted heatsink If board area is at a premium in your application then the top mounted heatsink should be used. This heatsink kit comes com- plete with screws and is mounted as shown in the diagram over. To fit the heatsink, place it in the required orientation, and tighten the four screws. The order number for the top mounted heatsink kit with Metric screws is: NFC40-HTSK-T. The order number for the top mounted heatsink kit with Imperial screws is: NFC40-HTSK-T-I. Side mounted heatsink With many applications, e.g. rack systems, the profile must be kept to a minimum. The side mounted heatsink is intended to meet the requirements of low profile applications. The NFC40 with this heatsink option is 12.7mm (0.5 inch) high. The kit contains two side mounted heatsinks, which must be fitted opposite to one another on the NFC40. The order number for the side mounted heatsink is: NFC40-HTSK-S Factory fitted heatsinks As a further option, Artesyn Technologies offers factory fitted heatsinks. Simply add the suffix as described by the diagrams above to the part number: e.g. NFC40-48S12-MY or NFC40- 48S12-1Y for Metric and Imperial screws respectively.
