  • Wirewound vs. Film Resistors for Precision Applications
    carbon resistor characteristics. On the good side, they can be made small and are low cost in high quantities. However, they cannot have tight resistance tolerances (>0.1%), they have large TCR (50-100ppm/C) and they are unstable (500-1000ppm/yr.) Thick film technology is especially important in hybrid
  • Amplifying High-Impedence Sensors ? Photodiode Example
    is Select the feedback resistor value to give a high gain to must flowforced to be at ground potential and I S . Usually, this gain is high enough to use most of theI S. This combination of effects creates anthrough R F is at its extremeop amp's output voltage swing when I Soutput voltage of I R . S
  • Low Frequency Phase Shift in LIVM Sensors as a Function of Discharge Time Constant and Frequency
    Low Impedance Voltage Mode (LIVM) sensors are piezoelectric devices with integral FET impedance converting amplifiers. To bias the amplifier, a high value resistor is placed in parallel with the gate of the FET and the crystal element. The discharge time constant (TC) of the sensor is the product of this
  • Digital Multimeter Smart Tweezers FAQ
    voltage measurement is done; and. b) the Test Frequency is set to 10KHz. In the latter case Smart Tweezers do not turn off automatically due to parasitic capacitance of the tweezers tips leading to a current flowing through it. Change Test Frequency to Auto after measuring something at high frequency.
  • Equalizer (.doc)
    The chip 0603 Equalizers from Thin Film Technology (TFT) are high frequency passive equalization modules that utilize precision thin film resistor, inductor and HF monolithic capacitors to produce high pass filter functions for loss compensation purposes. The wide bandwidth of these components
  • 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
  • Regenerative Power Units Save Energy
    When an electric motor is driven by a variable frequency drive (VFD), electric power delivered to the motor is regenerated while the motor decelerates by applying negative torque to the motor shaft. Usually energy storage capacity inside the VFD is very limited so regenerative energy should
  • Interfacing a Micro Crystal MS1V-T1K 32.768 kHz Tuning Fork Crystal to a PIC16F690/SS
