  • Resistance and Capacitance Meter Using a PIC 16C622
    The PIC16C62X devices create a new branch in Microchip?s PIC16CXXX 8-bit microcontroller family by incorporating two analog comparators and a variable voltage reference on-chip. The comparators feature programmable input multiplexing from device inputs and an internal voltage reference
  • Capacitance Set Point Stability During Random Vibration Test
    The variable end of a CSV4-900-01 vacuum capacitor was bolted to a thick phenolic disc. This disc was clamped into a rigid test fixture, which was bolted securely to the working table of the vibration test rig (Figure 1). The fixed end of the vacuum capacitor was left free to
  • On the Compression and Blocking Distortion of Semiconductor-Based Varactors
    -The effective capacitance of variable reactors (varactors) can be modulated by the magnitude of applied RF signals, resulting in troublesome detuning issues in resonators constructed. with these devices. In this paper, the fundamental causes behind these issues are investigated through the use
  • Tiltmeter Temperature Coefficients: Source, Definition and Use to Improve Accuracy
    Environmental temperature changes alter the mechanical and electrical characteristics of all instrumentation. Metals expand and contract, and electrical properties such as resistance and capacitance rise and fall. These effects change instrument output and lessen the accuracy of the measured
  • Passive noise reduction - options for axial and centrifugal fans, Appliance DESIGN, February 2015
    One undisputed requirement for a high performance system is the. ability to closely match its output to the actual demand. Comfort, health, process variance, sound emissions, and energy performance benefit from enabling motors for variable speed operation. What are the potential side effects
  • Electrolytic Tiltmeter Temperature Coefficients
    Environmental temperature changes alter the mechanical and electrical characteristics of all instrumentation. Metals expand and contract, and electrical properties such as resistance and capacitance rise and fall. These effects change instrument output and lessen the accuracy of the measured
  • Selecting an ESD Suppressor (.pdf)
    Littelfuse offers three device technologies for the suppression of ESD events and other EMC-related transients. These are the MultiLayer Metal Oxide Varistor, silicon (SCR/Diode Array and TVS Avalanche Diode Arrays) and Polymeric Voltage Variable Material technologies. Though these products have
  • Predicting Operating Temperature and Expected Lifetime of Aluminum-Electrolytic Bus Capacitors with Thermal Modeling
    Large-can aluminum electrolytic capacitors are widely used as bus capacitors in variable-speed drives, UPS systems and inverter power systems. Accurate thermal modeling of the capacitor's internal temperature is needed to predict life, and this is a challenge because of the anisotropic nature
