Announcement of new N series Heat Sinks
Issue Date: 2004/09/20
Revised Date: 2004/09/27

Alpha has expanded its wide range of off-the-shelf products to meet with our customer's requirements.

N Series (Natural-convection) heat sinks feature a hexagonal shaped fin (2.4mm thickness) and 6.43-7.00mm fin gap.
This series has been designed for applications with low or no airflow. In addition, the hexagonal shaped fin is less directional, so the N Series can be used in areas subject to omnidirectional airflow.

Compared to other, comparably sized heat sinks (For example, the S Series, which features a square shaped fin), the thermal resistance at natural convection (0 LFM) has improved by over 12% in our tests.

Please visit our online catalog for details regarding the N Series.
The N sereis is released in the following sizes:

Product name Base size (mm) Height (mm) Base thickness (mm)
N60-**B 60 x 60 20 / 25 / 30 / 35 / 40 4.0
N70-**B 70 x 70 4.5
N80-**B 80 x 80 5.0
N90-**B 90 x 90 5.5
N100-**B 100 x 100 6.0

Alpha offers several standard heat sink series that covers a wide variety of application requirements. By consulting the on-line catalog, an optimized choice can be made based on air flow, power, board density, heat source size, etc...
