Buzzers (507)

Buzzers

Passive buzzers are audio signaling devices that produce sound to indicate a button press. They are of different types such as Piezo Buzzers that use oscillating voltage, electromechanical buzzers that use self-oscillations as in a horn, electro-acoustic buzzers that convert electrical signals into sound vibrations, and more. While choosing the ideal buzzer for your project, consider the product size, terminal type, sound output, voltage among other factors. Here, we offer buzzers at sound levels from 80 dB to 105 dB.

Thermistors (1154)

Thermistors

A thermistor acts as a temperature sensor and changes its resistance value as the surrounding temperature changes in a device. Widely used for measurement and control, thermistors are categorized as two types - PTC thermistors and NTC thermistors. You’ll find both types here at Future Electronics. For CRT displays, 3D printers, heating equipment or other appliances, you’ll find suitable thermistors for every application.
