The Φ9.0x5. 5H 3VDC active magnetic buzzer is a self-drive, 3V magnetic buzzer aimed at space sensitive applicatons. Small and low-profile At a compact size of 9.0mm in diameter and only 5.5mm profile, it is one of the lowest profile buzzers in the industry. Being an "active" device it contains its own oscillation circuit and will respond with a fixed-frequency tone (usually around 2300Hz) when a DC voltage is connected, making design and integration easier. Working at a low voltage of 3VDC, and with audible output up to 80 dB, it is ideal for bright clear launch alert in portable & battery powered devices.
Key Features
Ultra-Compact Size: Miniature size (9 mm diameter, 5.5mm height) for low-profile design applications; ideal relay alternative.
Easy "Plug & Sound" Operation: With the active buzzer, it's a piece of cake to make noise—just supply DC voltage and you’re good to go!
Low Voltage Capability:Perfect for 3V devices, it will work better with the applications, that are powered by two AA/AAA batteries.With higher reduction ratioIt provide you with more variation options for your project.
LOUD Enough to Wake You Up: 80 dB loud sound, super loud but not deafening.
Low Consumption: Efficient design keeps itself from causing any harmful impact to your battery that make good use of it for high energy supply in portable, mobile and compact devices.
Polarity Sensitive: clear positive (+) and negative (-) markings for easier installation.
