1. Product Overview:

️· Product: AH Series Extrusion Heatsinks. These are aluminum heatsinks designed for heat dissipation.
️· Material: Aluminum alloy 6063-T5.
️· Compliance: RoHS compliant (meaning they meet environmental regulations regarding hazardous substances).

2. Ordering Information (How to Order):

The order code follows this structure: AH [Extrusion Style] [Series/Variant Code] [Length Code] [Modification Code]

️· AH: Indicates the series.
️· Extrusion Style: Refers to the specific heatsink profile. See the visual diagrams in the document for the look of each profile.
️· Series/Variant Code: Indicates any specific variation within that extrusion style.
️· Length Code: Specifies the length of the heatsink in inches (e.g., 12300 = 12.3 inches).
️· Modification Code:
- N: No modification (standard).
- X: Consult factory for special modifications.

3. Finishes (represented by letters in the order code):

️· A: Black Anodized
️· C: Gold Chromate
️· F: Clear Chromate
️· G: Green Anodized
️· K: Clear Anodized
️· R: Red Anodized
️· V: Unfinished (natural aluminum)

4. Technical Specifications:

️· Rθ (°C/W): Represents the thermal resistance. This is a key performance metric – lower values indicate better heat dissipation. This value is determined by:
- Mounting surface temperature rise (75°C)
- Natural convection
- Black Anodized finish
- Extrusion length (76 mm / 3 inches)

5. Visual Representation:

️· The document includes diagrams of various extrusion profiles (e.g., AH33000, AH54100, AH80126, etc.). These are *not to scale*. Refer to the table of dimensions for actual measurements.

6. Table of Dimensions:

️· A detailed table lists the specifications for numerous heatsink profiles. This table includes:
- Extrusion Style (e.g., AH33000, AH54100)
- Dimensions (height, width, length, etc.).
- Rθ (°C/W) – Thermal resistance.
