MK1-100-53-10-12.7 electrical component is a sensor resistor whose resistance changes with temperature. Based on the temperature coefficient, it is classified into positive temperature coefficient (PTC) thermistors and negative temperature coefficient (NTC) thermistors. The resistance of a PTC thermistor increases as temperature rises, while the resistance of an NTC thermistor decreases as temperature rises; both belong to semiconductor devices.

MK1-100-53-10-12.7 electrical component composition

The circuit board mainly consists of pads, vias, mounting holes, traces, components, connectors, copper pours, electrical boundaries, etc. (1) Pad: A metal hole used for soldering component pins. (2) Via: Includes metal vias and non-metal vias; metal vias are used to connect component pins between layers. (3) Mounting hole: Used to fix the circuit board. (4) Trace: Copper film of the electrical network used to connect component pins. (5) Connector: Components used for connection between circuit boards. (6) Copper pour: Copper filling for the ground network, which can effectively reduce impedance. (7) Electrical boundary: Used to determine the dimensions of the circuit board; no components on the board may exceed this boundary.

MK1-100-53-10-12.7 electrical component characteristics

Sensitivity refers to the ratio of the change in output to the change in input of a sensor under steady-state operating conditions. It is the slope of the output-input characteristic curve. If there is a linear relationship between the sensor's output and input, then the sensitivity S is a constant. Otherwise, it will vary with the change in input. The dimension of sensitivity is the ratio of the dimensions of the output and input quantities. When the dimensions of the sensor's output and input quantities are the same, sensitivity can be understood as the amplification factor. Increasing sensitivity yields higher measurement accuracy. However, the higher the sensitivity, the narrower the measurement range, and stability often deteriorates.

MK1-100-53-10-12.7 electrical component structure

The structure and materials of new high-voltage Schottky diodes differ from those of traditional Schottky diodes. Traditional Schottky diodes are formed by the contact between metal and semiconductor. Metals such as aluminum, gold, molybdenum, nickel, and titanium can be selected, while the semiconductor is typically silicon or gallium arsenide. Since electrons have higher mobility than holes, N-type semiconductor material is chosen as the substrate to achieve good frequency characteristics. To reduce the junction capacitance of the Schottky diode and increase the reverse breakdown voltage without causing excessive series resistance, a high-resistance N- thin layer is usually epitaxially grown on an N+ substrate. As is known, there are a large number of conductive electrons inside a metal conductor. When metal contacts a semiconductor (with a distance on the order of atomic size), the Fermi level of the metal is lower than that of the semiconductor. In the metal and at the energy levels corresponding to the semiconductor conduction band, the electron density is lower than that in the semiconductor conduction band. Therefore, after contact, electrons diffuse from the semiconductor to the metal, causing the metal to become negatively charged and the semiconductor positively charged. Since metal is an ideal conductor, the negative charge is distributed only within a thin layer on the surface with atomic-scale thickness. For N-type semiconductors, the donor impurity atoms that lose electrons become positive ions and are distributed over a larger thickness. The result of electron diffusion from the semiconductor to the metal forms a space charge region, a built-in electric field, and a potential barrier, with the depletion layer existing only on the N-type semiconductor side (the entire barrier region falls on the semiconductor side). The direction of the built-in electric field in the barrier region points from the N-type region to the metal. As thermionic emission increases the built-in field, the drift current, which is opposite to the diffusion current, increases, eventually reaching dynamic equilibrium and forming a contact potential barrier between the metal and the semiconductor, known as the Schottky barrier. When the external voltage is zero, the electron diffusion current equals the reverse drift current, achieving dynamic equilibrium. When forward bias is applied (positive voltage to the metal, negative voltage to the semiconductor), the built-in field is weakened, the barrier on the semiconductor side is lowered, and a forward current flows from the metal to the semiconductor. When reverse bias is applied, the built-in field is strengthened, the barrier height increases, and a small reverse current flows from the semiconductor to the metal. Therefore, SBD, like a PN junction diode, is a nonlinear device with unidirectional conductivity.
