The 260-4T5E is an epoxy-insulated cup clip from the 260 Series, designed to provide thermal management for TO-5 case style semiconductors. It features a tapped base with a #4-40 UNC thread and a depth of 0.093 inches. Constructed with a beryllium copper cup and a brass base, both finished with black ebonol 'C', this clip provides a thermal resistance of 14° C/W. The epoxy insulation offers a breakdown voltage of 500 VAC, making this component suitable for applications requiring reliable heat dissipation and electrical isolation in a continuous operating temperature range of -73°C to +149°C.
