Heat Sinks for Quarter Brick DC/DC Converters RoHS Compliant 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 * Simple assembly * High performance QPad3TM 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 241402B91200G Lengthwise 6.0 (0.24) A 241404B91200G Lengthwise 11.4 (0.45) A 241409B91200G Lengthwise 22.9 (0.90) A 241402B92200G Crosswise 6.0 (0.24) B 241404B92200G Crosswise 11.4 (0.45) B 241409B92200G Crosswise 22.9 (0.90) B Optional Hardware Kit: Four M3 x 0.5 x 4.5 screws with captive lock washer individually bagged Use code 03 in the 11th & 12th digit Example: 241409B92203G Hardware Kit included Q-pad is a registered trademark of the Bergquist Company FOR MORE INFORMATION, VISIT OUR WEB SITE: WWW.AAVIDTHERMALLOY.COM TEL: (603) 224-9988 RoHS Compliant Heat Sinks for Quarter Brick DC/DC Converters Lengthwise AirFlow Figure A 37.0 (1.46) 47.2 2X (1.86) 58.0 (2.28) 12 0.6 10 0.5 8 0.4 6 0.3 4 0.2 2 0.1 0 2.0 (0.08) 4X 0 100 200 300 400 500 600 700 800 Pressure Drop (in. of H2O) 26.2 (1.03) 2X "H" Thermal Resistance (C / W) Device Case to Ambient o 3.30 THRU 4X 0 900 1000 Air Flow (LFM) 241402B91200G 241404B91200G 241409B91200G Crosswise AirFlow Figure B 58.0 (2.28) 6 0.6 5 0.5 4 0.4 3 0.3 2 0.2 1 0.1 0 0 26.2 (1.03) 2X 37.0 (1.46) 100 200 241402B92200G 241404B92200G 241409B92200G 2.0 (0.08) 4X 300 400 500 600 700 800 0 900 1000 Air Flow (LFM) North America Europe - Italy Asia - Taiwan Asia - Singapore 70 Commercial Street Concord, NH 03301 TEL: (603) 224-9988 FAX: (603) 223-1790 EMAIL: info@aavid.com Via Aprile,32 40057 Cadriano (BO), Italy TEL: (39) 051 764011 FAX: (39) 051 764090 EMAIL: sales.it@aavid.com 14F-4, NO. 79, Hsin Tai Wu RD.
