FA-T220-25E-ND

Product catalog summary

Overview: The document provides technical specifications and ordering information for the F and R Series heatsinks designed for TO-218, TO-220, and TO-247 devices. These heatsinks are used to dissipate heat in electronic components, ensuring optimal performance and longevity.

Specifications: The heatsinks are available in various heights ranging from 1.0 inch (25.4 mm) to 2.5 inches (63.5 mm). They are made from 6063-T5 aluminum with a black anodized finish, which enhances heat dissipation. The thermal resistance varies from 3.0°C/W to 4.8°C/W depending on the model, with natural convection as the cooling method.

Key Features: The heatsinks are designed for vertical mounting with solderable pins and are compatible with Ohmite resistor series TBH25, TCH35, TEH70, and TEH100. They are RoHS compliant, ensuring they meet environmental and safety standards.

Performance Data: Graphs included in the document illustrate the relationship between heat dissipation (in watts) and air velocity (in ft./min.), as well as thermal resistance from the mounting surface to ambient temperature. These graphs help in understanding the efficiency of heat dissipation at different air velocities.

Ordering Information: The document lists standard part numbers for both the R Series (RA-T2X) and F Series (FA-T220) heatsinks, with details on dimensions and packaging. The part numbers indicate the series, height, and finish of the heatsinks.

Dimensional Changes: A notice indicates that the dimensions provided are for products manufactured after September 2012, highlighting any changes in design specifications.
