TIR300CU — common questions
Replacing another vendor’s TIM or need a stack review? Send drawings — applications responds quickly.
Talk to an engineerWhat is the nominal thermal conductivity of TIR300CU?
The customer workbook lists nominal through-plane conductivity as — W/m·K. What you measure depends on pressure, gap, and fixture — use the technical documentation as the reference.
Can Ziitek supply TIR300CU die-cut or in custom thickness?
Yes — send DXF/DWG outlines and stack height. Graphite sheets for thermal management parts are routinely converted at Ziitek; tolerances depend on thickness and geometry.
Where is the documentation for TIR300CU?
Download the technical documentation from this page when available. If your revision differs, name the file from your RFQ so applications engineering matches it.
Is TIR300CU RoHS-aligned?
Ziitek targets RoHS-oriented formulations across TIM lines. Cite the compliance block for audits and tell us if you need additional regional substance lists.
