Heat Sinks for Quarter Brick RoHS Compliant DC/DC Converters STANDARD THERMAL SOLUTIONS FOR QUARTER BRICK CONVERTERS Aavid Thermalloy heat sinks are designed for engineers seeking a complete off-the-shelf cooling solution for industry standard quarter brick converters. Unlike other converter heat sinks, Aavid designs feature thin fin geometry which increases thermal performance and reduces pressure drop. In addition, all heat sinks are ready for mounting with interface material pre-applied which streamlines procurement and assembly. APPLICATION NEED: FEATURES AND BENEFITS: Maximum Performance High fin density has more surface area for heat transfer, despite small foot print. Low Pressure Drop Thin fin geometry improves system airflow and reduces fan costs. Fits industry standard Quarter Brick modules Hole pattern fits 1/4 brick DC/DC Converters from top manufacturers like Delta, Emerson and Tyco Optimal configuration Lengthwise and crosswise fin orientations in three fin heights to allow a precise match to the application TM Simple assembly High performance QPad3 interface pad saves time and optional hardware kit provides the complete solution under a single part number ORDERING INFORMATION: Part Number Fin Configuration H height Figure Optional Hardware Kit: Four M3 x 0.5 x 4.5 screws with 241402B91200G Lengthwise 6.0 (0.24) A captive lock washer individually bagged 241404B91200G Lengthwise 11.4 (0.45) A Use code 03 in the 11th & 12th digit 241409B91200G Lengthwise 22.9 (0.90) A Example: 241409B92203G 241402B92200G Crosswise 6.0 (0.24) B Hardware Kit included 241404B92200G Crosswise 11.4 (0.45) B 241409B92200G Crosswise 22.9 (0.90) B Q-pad is a registered trademark of the Bergquist Company FOR MORE INFORMATION, VISIT OUR WEB SITE: WWW.AAVIDTHERMALLOY.COM TEL: (603) 224-9988Heat Sinks for Quarter Brick RoHS Compliant DC/DC Converters Lengthwise AirFlow Figure A 3.30 THRU H 4X 0.6 12 0.5 10 8 0.4 26.2 37.0 (1.03) (1.46) 6 0.3 2X 4 0.2 2 0.1 0 0 47.2 2X 2.0 0 100 200 300 400 500 600 700 800 900 1000 (1.86) (0.08) Air Flow (LFM) 241402B91200G 58.0 4X (2.28) 241404B91200G 241409B91200G Crosswise AirFlow Figure B 3.30 THRU H 4X 6 0.6 0.5 5 4 0.4 47.2 58.0 1.86) 3 0.3 (2.28) 2X 2 0.2 1 0.1 0 0 0 100 200 300 400 500 600 700 800 900 1000 241402B92200G Air Flow (LFM) 26.2 241404B92200G 2.0 (1.03) 241409B92200G (0.08) 2X 4X 37.0 (1.46) North America Europe - Italy Asia - Taiwan Asia - Singapore 70 Commercial Street Via Aprile,32 14F-4, NO. 79, Hsin Tai Wu RD. 31 Admiralty Road, 06-01 Concord, NH 03301 40057 Cadriano (BO), Italy SEC. 1, Hsi Chih Singapore 739984 TEL: (603) 224-9988 TEL: (39) 051 764011 Taipei Hsien TEL: 65 63628388 FAX: (603) 223-1790 FAX: (39) 051 764090 Taiwan FAX: 6563628588 EMAIL: info aavid.com EMAIL: sales.it aavid.com TEL: 011(886) 226989888 FAX: 011(886) 226989808 PLEASE NOTE: Any information furnished by Aavid Thermalloy is believed to be accurate and reliable, but our customers bear all responsibility for use and applications of Aavid Thermalloy products.
