When the temperature reaches the phase change range of 45–55℃, the pads soften and transition to a liquid state. Delivering wet-out performance comparable to thermal paste, they effectively fill gaps between heat sinks and electronic components. Custom die-cut into any shape per customer requirements, these pads offer convenience, high reliability, and straightforward application COD: SP205A-30Categorie: [Materiali per l'interfaccia termica](https://www.sheenmaterials.com/it/tim/) , [Cuscinetti termici](https://www.sheenmaterials.com/it/thermal-pads/) , [Materiale per interfaccia termica a cambiamento di fase](https://www.sheenmaterials.com/it/phase-change-thermal-interface-material/) Condividi il tuo amore[https://www.facebook.com/sharer/sharer.php?u=https%3A%2F%2Fwww.sheenmaterials.com%2Fit%2Fphase-change-thermal-pad-3w%2F](https://www.facebook.com/sharer/sharer.php?u=https%3A%2F%2Fwww.sheenmaterials.com%2Fit%2Fphase-change-thermal-pad-3w%2F) [https://twitter.com/intent/tweet?url=https%3A%2F%2Fwww.sheenmaterials.com%2Fit%2Fphase-change-thermal-pad-3w%2F&text=SP205A-30%20Phase%20Change%20Thermal%20pad%203.0W%2FmK](https://twitter.com/intent/tweet?url=https%3A%2F%2Fwww.sheenmaterials.com%2Fit%2Fphase-change-thermal-pad-3w%2F&text=SP205A-30%20Phase%20Change%20Thermal%20pad%203.0W%2FmK) [#](#) [https://www.linkedin.com/shareArticle?url=https%3A%2F%2Fwww.sheenmaterials.com%2Fit%2Fphase-change-thermal-pad-3w%2F&title=SP205A-30%20Phase%20Change%20Thermal%20pad%203.0W%2FmK](https://www.linkedin.com/shareArticle?url=https%3A%2F%2Fwww.sheenmaterials.com%2Fit%2Fphase-change-thermal-pad-3w%2F&title=SP205A-30%20Phase%20Change%20Thermal%20pad%203.0W%2FmK) - [Descrizione](#tab-description) ## Informazioni tecniche [Specifiche tecniche](#sp-specs) [Applicazioni](#sp-apps) [Note sull'installazione](#sp-install) [Download e FAQ](#sp-faq) ### Specifiche tecniche | Proprietà | SP205A-30 | Metodo di prova | | --- | --- | --- | | Colore | Grigio | Visivo | | Conduttività termica | 3.0 W/m·K | ASTM D5470 | | Thermal Impedance (@50 psi) | 0,05 ℃-in²/W | ASTM D5470 | | Spessore | 0.20 mm | ASTM D751 | | Customized Thickness | 0.13 ~ 0.5 mm | - | | Thickness Tolerance | ±20% | - | | Densità | 2.85 g/cm³ | ASTM D792 | | Phase Change Temp. | 45 ~ 55℃ | - | | Temperatura di esercizio. | -40 ~ 125℃ | - | | Costante dielettrica (@1MHz) | 3.0 | ASTM D150 | | Resistività di volume | 2.0 × 10¹⁰ Ω·m | ASTM D257 | | RoHS | PASSO | IEC 62321 | | Alogeno | PASSO | EN 14582 | | RAGGIUNGERE | PASSO | EN 14372 | ### Applicazioni #### Applicazioni consigliate - High-frequency microprocessors - Laptops & desktop computers - Computer servers - Memory modules - Integrated chips (IC) - LED lighting products - CPU/GPU chips - Control boards #### Non consigliato per - Large gap-filling applications - Interfaces requiring thick compressible gap fillers - Highly uneven interfaces without sufficient clamping pressure ### Note sull'installazione - Solid at room temperature for easier handling and assembly. - Softens within 45–55℃ to improve interface wet-out during operation. - No preheating required. - Suitable for sheet form and customized die-cut form. - Store in a cool, dry, and well-ventilated place away from open flame. - Durata di conservazione: 12 mesi. ### Download e FAQ [Download Datasheet](https://www.sheenmaterials.com/wp-content/uploads/2026/03/SP205A-30-datasheet-2026-Phase-Change-Thermal-Interface-Sheet.pdf) **Q1.
