Laird Technologies Introduces T-gard 20 Thermally Conductive Insulating Material.Thermally Conductive Insulator insulator Substance that blocks or retards the flow of electric current or heat. An insulator is a poor conductor because it has a high resistance to such flow. Electrical insulators are commonly used to hold conductors in place, separating them from one another and from Ideal for Personal Computer Power Supply Applications ST. LOUIS -- Laird Technologies, a leading designer and manufacturer of antenna, electromagnetic interference See EMI. (EMI (ElectroMagnetic Interference) An electrical disturbance in a system due to natural phenomena, low-frequency waves from electromechanical devices or high-frequency waves (RFI) from chips and other electronic devices. Allowable limits are governed by the FCC. ) shielding, telematics Originally coined to mean the convergence of telecommunications and information processing, the term later evolved to refer to automation in automobiles. GPS navigation, integrated hands-free cellphones, wireless communications and automatic driving assistance systems all come under the and thermal management solutions, introduced today its T-gard 20 high performance, cost effective electrically conductive insulating material. This product is designed for computer power supply applications. T-gard 20 features a 9000 Vac dielectric dielectric (dī'ĭlĕk`trĭk), material that does not conduct electricity readily, i.e., an insulator (see insulation). A good dielectric should also have other properties: It must resist breakdown under high voltages; it should not breakdown voltage Breakdown Voltage (Insulator) = The minimum voltage that causes a portion of an insulator to become electrically conductive. Breakdown Voltage (diode) = The minimum reverse voltage to make the diode conduct in reverse. (DBV DBV Decibels DBV Dubrovnik, Croatia (Airport Code) DBV Deutscher Bibliotheksverband eV DBV Deutscher Baseball und Softball Verband (German Baseball and Softball Association) DBV Dollar Bill Validator ) that contributes to its high electrical reliability. Customers won't have to worry about dielectric isolation in their application. T-gard 20 has two times the DBV of the competitive materials. "The product features consistent dielectric strength In physics, the term dielectric strength has the following meanings:
T-gard 20 produces the same thermal performance whether the device is screw or clip mounted. In either situation the thermal impedance of T-gard 20 is 0.6xC-in2/watt. The phase change coating melts into a grease-like paste at 52xC, and completely wets out the interface to achieve consistent thermal performance on rough and non flat surfaces. The base polyester film has a tensile strength tensile strength Ratio of the maximum load a material can support without fracture when being stretched to the original area of a cross section of the material. When stresses less than the tensile strength are removed, a material completely or partially returns to its of 30 kpsi to prevent cut through on screw mounted TO-220 assemblies. T-gard 20 also has high cut-through resistance. The film is flexible so it does not crack or flake like mica. "The consumer market is demanding more power out of their primary power supplies," said Kranz. "The T-gard 20 gives them the extra performance without the extra price." The T-gard 20 is another offering in the family of T-gard insulators, which are designed to provide superior thermal, mechanical and electrical operation compared with other fiberglass products. The product is available now and costs less than $0.01 per square inch. http://www.lairdtech.com/pages/products/T-gard20.asp About Laird Technologies Laird Technologies supplies performance critical products, co-designed in conjunction with customers, which are essential in enabling and protecting the functionality of electronic devices and wireless applications.
