These NTC thermistors are little components that help measure temperature in all sorts of electrical stuff. The model is NTC1.5D-15, and they have a resistance of 1.5 ohms at 25°C. They can handle a max steady current of 8A and work in a wide temperature range from -55°C to 315°C—pretty impressive! Each thermistor has a head diameter of 15mm, pin length of 27mm, and pin pitch of 7.5mm. They're made from durable materials, so they're stable and last a long time. You get 10 pieces in the pack. They're commonly used in household appliances, air conditioners, water heaters, motor controls, and even light bulb regulators. Just connect them to the circuit, and they help monitor or limit current based on temperature. Handy for DIY repairs or electronic projects. Just make sure the specs match what you need before buying!
