Bourns electrical components Germany Bourns model Bourns price

Bourns electrical components are devices for transmitting electrical energy or signals, typically composed of several wires or groups of wires. They consist of one or more mutually insulated conductors with an outer insulating protective layer, forming wires that transmit power or information from one location to another. Typically, they are rope-like cables formed by twisting several wires or groups of wires (each group having at least two), with mutual insulation between each group, often twisted around a central core, and the entire assembly is covered with a highly insulating sheath. Cables feature internal conductivity and external insulation.

Bourns electrical components classification

Oscillators are mainly divided into RC, LC oscillators, and crystal oscillators. 1. RC oscillators using an RC network as the frequency-selective phase-shift network are collectively referred to as RC sine wave oscillators, belonging to audio oscillators. 2. LC oscillators using an LC resonant circuit as the phase-shift and frequency-selective network for positive feedback are called LC oscillators. 3. Crystal oscillators are oscillators whose oscillation frequency is controlled by a quartz crystal. 4. Temperature coefficient oscillators refer to a type of oscillator where there is a specific relationship between the oscillation frequency and temperature, meaning different temperatures correspond to different oscillation frequencies. Conversely, by measuring the output frequency of the oscillator, the temperature value can be determined.

Functions of capacitors: 1. Capacitors used in coupling circuits are called coupling capacitors. This type of capacitor circuit is widely used in RC-coupled amplifiers and other capacitive coupling circuits to block DC and pass AC. 2. Capacitors used in filtering circuits are called filter capacitors. This type of capacitor circuit is used in power supply filters and various filter circuits; filter capacitors remove signals within a certain frequency band from the total signal. 2. Capacitors used in decoupling circuits are called decoupling capacitors. This type of capacitor circuit is used in the DC voltage supply circuits of multi-stage amplifiers; decoupling capacitors eliminate harmful low-frequency coupling between amplifier stages. 3. Capacitors used in high-frequency oscillation suppression circuits are called high-frequency suppression capacitors. In audio negative feedback amplifiers, this type of capacitor circuit is adopted to suppress potential high-frequency self-oscillation, thereby eliminating possible high-frequency whistling from the amplifier. 4. Capacitors used in LC resonant circuits are called resonant capacitors; this type of capacitor circuit is required in both LC parallel and series resonant circuits. 5. Capacitors used in bypass circuits are called bypass capacitors. If a specific frequency band needs to be removed from a signal in a circuit, a bypass capacitor circuit can be used. Depending on the frequency of the signal being removed, there are full-frequency-domain (all AC signals) bypass capacitor circuits and high-frequency bypass capacitor circuits. 6. Capacitors used in neutralization circuits are called neutralization capacitors. This type of neutralization capacitor circuit is adopted in RF and IF amplifiers of radios and RF amplifiers of televisions to eliminate self-oscillation. 7. Capacitors used in timing circuits are called timing capacitors. Timing capacitor circuits are used in circuits that require time control through capacitor charging and discharging; the capacitor controls the magnitude of the time constant. 8. Capacitors used in integration circuits are called integrating capacitors. This type of integrating capacitor circuit is adopted in the synchronization separation circuit for potential field scanning to extract the field synchronization signal from the field composite synchronization signal. 9. Capacitors used in differentiation circuits are called differentiating capacitors. This type of differentiating capacitor circuit is adopted in flip-flop circuits to obtain peaked trigger signals, thereby extracting peaked pulse trigger signals from various (mainly rectangular pulse) signals. 10. Capacitors used in compensation circuits are called compensation capacitors. This type of low-frequency compensation capacitor circuit is used in the bass compensation circuit of cassette decks to enhance low-frequency signals in the audio output; there are also high-frequency compensation capacitor circuits. 11. Capacitors used in bootstrap circuits are called bootstrap capacitors. Common OTL power amplifier output stage circuits adopt this type of bootstrap capacitor circuit to slightly increase the amplitude of the positive half-cycle of the signal through positive feedback. 12. Capacitors used in crossover circuits are called crossover capacitors. Crossover capacitor circuits are used in loudspeaker crossover networks in speakers to ensure that tweeters operate in the high-frequency band, mid-range drivers operate in the mid-frequency band, and woofers operate in the low-frequency band. 13. This refers to the effective external capacitance that, together with the quartz crystal resonator, determines the load resonant frequency. Common standard values for load capacitance are 16pF, 20pF, 30pF, 50pF, and 104pF. Load capacitance can be appropriately adjusted according to specific conditions; through adjustment, the operating frequency of the resonator can generally be tuned to the nominal value.

1. Fuse resistors: Also known as fusible resistors, they serve the dual function of a resistor and a fuse under normal conditions. When a circuit fault causes their power consumption to exceed the rated power, they will blow like a fuse, disconnecting the connected circuit. Fuse resistors generally have small resistance values and low power ratings. 5. Sensitive resistors: These refer to resistors whose resistance values exhibit sensitivity to certain physical quantities (such as temperature, humidity, light intensity, voltage, mechanical force, and gas concentration). When these physical quantities change, the resistance value of the sensitive resistor changes accordingly, presenting different resistance values. Based on sensitivity to different physical quantities, sensitive resistors can be classified into types such as thermistors, humidity-sensitive resistors, photoresistors, varistors, force-sensitive resistors, magnetoresistors, and gas-sensitive resistors. The materials used for sensitive resistors are almost exclusively semiconductor materials, so these resistors are also called semiconductor resistors. The resistance of a thermistor changes with temperature; if the resistance decreases as temperature rises, it is a negative temperature coefficient (NTC) thermistor. NTC thermistors are widely used and can be further divided into general-purpose NTC thermistors, voltage-stabilizing NTC thermistors, and temperature-measuring NTC thermistors. A photoresistor's resistance changes with the intensity of incident light; when incident light increases, the resistance of the photoresistor decreases, and when incident light weakens, the resistance value increases.
