Buzzers on tape can be automatically processed

7 April 2004 Passive Components Information Security

If a buzzer can be made small enough, it can be delivered in tape ready for automatic processing. Murata has done this, and with no reduction in sound pressure level (SPL). The PKLCS1212E is 12 x 12 mm and taped on reels of 1000 pieces. It can be reflow soldered and has gold terminals, eliminating the need for lead (Pb) and making it compatible with conductive adhesive mounting.

Soldered or otherwise, the ability to process buzzers automatically gives high volume manufacturers a major improvement in productivity. There are other advantages too, piezo buzzers use less current than dynamic types and produce no magnetic disturbance.

Murata's minimum SPL of 75 dB is specified at 4 kHz, with a 3 V peak-to-peak square wave at 10 cm, and the operating temperature range is -20 to 70°C.
