IMT37312 electrical component is a sensor resistor whose resistance changes with temperature. Based on different temperature coefficients, it is divided into positive temperature coefficient thermistors and negative temperature coefficient thermistors. The resistance of a positive temperature coefficient thermistor increases as the temperature rises, while the resistance of a negative temperature coefficient thermistor decreases as the temperature rises; both belong to semiconductor devices.

IMT37312 electrical component structure

The rated current of the fuse element is not equal to the rated current of the fuse. The rated current of the fuse element is selected based on the load current of the protected equipment. The rated current of the fuse should be greater than the rated current of the fuse element and determined in coordination with the main electrical appliance. A fuse mainly consists of 12 parts: the fuse element, the housing, and the support. The fuse element is the key component controlling the fusing characteristics. The material, size, and shape of the fuse element determine the fusing characteristics. Fuse element materials are divided into two categories: low melting point and high melting point. Low melting point materials, such as lead and lead alloys, have a low melting point and fuse easily. Due to their higher resistivity, the cross-sectional size of the fuse element made from them is larger, generating more metal vapor during fusing, making them suitable only for fuses with low breaking capacity. High melting point materials, such as copper and silver, have a high melting point and do not fuse easily. However, due to their lower resistivity, they can be made with a smaller cross-sectional size than low melting point fuse elements, generating less metal vapor during fusing, making them suitable for fuses with high breaking capacity. The shape of the fuse element is divided into wire-shaped and strip-shaped. Changing the shape of the variable cross-section can significantly alter the fusing characteristics of the fuse. Fuses have various fusing characteristic curves, suitable for the needs of different types of protected objects.

IMT37312 electrical component applications

Thermistors can also be used as electronic circuit components for temperature compensation in instrument circuits and cold junction temperature compensation for thermocouples. Utilizing the self-heating characteristic of NTC thermistors enables automatic gain control, forming RC oscillator amplitude stabilization circuits, delay circuits, and protection circuits. When the self-heating temperature is much higher than the ambient temperature, the resistance is also related to the heat dissipation conditions of the environment. Therefore, this characteristic of thermistors is often utilized in anemometers, flow meters, gas analyzers, and thermal conductivity analysis to create specialized detection elements. PTC thermistors are mainly used for overheat protection of electrical equipment, contactless relays, constant temperature control, automatic gain control, motor starting, time delay, automatic degaussing of color televisions, fire alarms, and temperature compensation. Main disadvantages: (1) severe nonlinearity in the relationship between resistance and temperature; (2) poor consistency and interchangeability of components; (3) components are prone to aging and have poor stability; (4) except for special high-temperature thermistors, most thermistors are only suitable for the range of 0 to 151 °C, which must be noted during use.

IMT37312 electrical component classification

1. Classification by relay external dimensions: (1) miniature relay, (2) sub-miniature relay, (3) small miniature relay. 2. Classification by relay load: (1) micro-power relay, (2) weak-power relay, (3) medium-power relay, (4) high-power relay. 5. Classification by relay protection features: (1) Sealed relay: Contacts and coils are sealed inside a cover using welding or other methods, isolated from the surrounding medium, resulting in a low leakage rate. (2) Enclosed relay: Contacts and coils are protected by being enclosed (non-sealed) in a housing. (3) Open relay: Relays that do not use a protective cover to protect contacts and coils. Among the above relays, electromagnetic relays and reed relays are the most commonly used in electronic fabrication.
