SE300AB Thermal Gel 3.0W/mK
Use Range:
SE300AB 3.0W/mK Two-Part Thermal Gel (Thermal Putty) is a silicone resin-based flexible thermal gap filler. It cures to form an elastomer that delivers efficient heat transfer and reliable shock absorption, effectively protecting electronic components. The product features low thermal impedance, minimal silicone oil seepage, and superior extrusion properties. Once cured, the elastomer retains a consistent required thickness, providing reliable shock absorption; it can replace traditional thermal pads and boasts excellent reworkability. Thickness and shape can be precisely controlled via automated dispensing equipment.
Product Description
◆ Excellent thermal conductivity, available in options ranging from 2.0 to 8.0 W/m·K.
