Kitronik Miniature Buzzer 6v 10 Pack
KI 3306
These Miniature Buzzers are a low cost miniature transistor oscillator 6V buzzer with flying leads. They have a single-tone frequency of 400hz and a sound output of 75dB @ 200mm. They are rated for 4V - 8V (6V nominal) and a current of 25mA and the driver circuitry is built in. These buzzers are supplied as a pack of 10.
The buzzer unit is L23mm x W17mm x H15.5mm, with fixing centres at 27.5mm, which gives a total length measurement of 33.5mm. The colour-coded (red & black) flying leads are 100mm. To ensure optimum performance and to protect the buzzer, ensure that the supply (e.g. batteries) is connected in the correct configuration.

Kitronik Stereo Amplifier Kit
KI 2179
This stereo audio amplifier kit can be used with any personal stereo equipment, including MP3 players and Mobile devices, such as tablets and phones with a 3.5mm jack socket. The kit can be used in the classroom to teach electronics and product design. The M3 mounting holes in each of the corners make it straightforward to attach the kit firmly to an enclosure. As with all of our project kits, we have provided teachers with full documentation that can be used for lesson planning, they can be downloaded from the foot of the product description.
The kit features 2 x FM8002A mono amplifier ICs, one for each channel, which are surface-mounted components that come pre-fitted to the PCB. Once the rest of the circuit has been built and the speakers attached, the amplifier outputs 1.5W per channel into 8ohm speakers. The kit is supplied with a 3 x AA battery holder (with flying leads) for powering the amplifier, the kit is not supplied with batteries.
