  • Which is Better? Resistive Heaters vs. PTC Heaters
    of heaters that may be used, as there is a risk of fire or high power draw inside an office building.
  • ANN-8804 - SMD Power Handling Considerations
    This document describes the power rating of high power surface mount resistive products. Furthermore,. techniques for maximizing power handling performance of these parts are detailed.
  • Selecting SCR Power Controllers to Reduce Heat Control System Panel Costs
    be controlled, and there is always the question of what to make and what to buy as a sub-assembly. These are particularly sensitive issues in the construction of SCR power control panels used for resistive and inductive heaters in ovens, kilns, environmental chambers, furnaces, and other manufacturing
  • High Spur Free Dynamic Range RF Photonic Links allow MIL SATCOM and RF Distribution Networks to Leverage Optical Communication Infrastructure (.pdf)
    technology to the civilian and defense markets provided limited deployment options due in large part to their high costs, limited RF performance envelope, and prohibitive size, weight and power (SWaP) requirements. In addition to these technical limitations, there existed the ever present cultural
  • History and Properties of Thermoelectric Devices
    devices: thermal conductivity and electrical resistivity. The ideal thermoelectric material has a high Seebeck coefficient and low electrical resistivity, so little heat is generated from the electrical current flow, and low thermal conductivity, so little heat is transferred from the hot junction
  • "Improved Capacitor Using Amorphous RuO2"
    power capability or vice versa, but rarely can both be optimized at once. For instance, many carbon-based double layer capacitor systems have high energy density, but. they also posses a higher resistance than systems containing more electrically conductive. materials.
  • AG312: Design with PIN Diodes
    is a current controlled resistor at radio and microwave frequencies. It is a silicon semiconductor diode in which a high resistivity intrinsic I-region is sandwiched between a P-type and N-type region. When the PIN diode is forward biased, holes and electrons are injected into the I-region
  • Derating For Real World Conditions
    of bimetal. Low. resistivity elements experience lower I²R heat effect. High resistivity elements exhibit. more I²R effect. This self-heating characteristic plays a prominent role in derating the. performance of a thermal control and is especially useful when thermal controls are. utilized in inductive
  • Precision RTD Instrumentation for Temperature Sensing
    resolution. Only one biasing resistor, R A Precision RTD (Resistive Temperature Detector) needed to set the measurement resolution ratio instrumentation is key for high performance thermal (Equation 1). management applications. This application note shows how to use a high resolution Delta-Sigma
  • Design Considerations for Thermal Controls
    particular application. This operating feature is especially important when a thermal control is being. used as a high limit safety on inductive type loads. Increasing or decreasing the resistivity of the bimetallic element enables you to select a. thermal control that maximizes the operating performance
  • Dielectric Materials for Use in Radomes
    factor due to the loss tangent's definition as the ratio of the resistive power loss to applied field power within the capacitor. Minimizing dielectric loss as heat is extremely important for many applications pertaining to capacitance and insulating materials. ASTM D2520 also tests for Loss Tangent
  • 3D Scanners Take Volume Measurement to a New Level
    a very high level of volume accuracy in silos up to about 45' in diameter. At the top of the model spectrum is the model MV, which does everything the M does, plus adds a unique visualization feature. Using complex algorithms and a lot of processing power, this model generates a 3D image
  • Tin Vs. Bare
    There seems to have always been differences of opinion when it comes to certain topics, be it politics, sports and even which drive-through has the best coffee. Another age old argument that we face as a high-end data cable producer is whether or not a data grade copper conductor should be plated
