(1/2) Conformity to RoHS Directive Piezoelectronic Buzzers PB Series(Pin Terminal/Lead) FEATURES  The PB series are high-performance buzzers with a unimorph piezoelectric ceramic element and an integral self-excitation oscillator circuit.  They exhibit extremely low power consumption in comparison to electromagnetic units.  They are constructed without switching contacts to ensure long life and no electrical noise.  Compact, yet produces high acoustic output with minimal voltage. APPLICATIONS Fire alarms, smoke detectors, home security systems, call buzz- ers, car alarm systems, clocks, and cash registers.

TERRIFIC RESOURCE

star star star star star

This company has been a terrific help to us (I work for Trican Well Service) in sourcing the Micron Ram Memory we needed for our Siemens computers. Great service! And great pricing! I know when the product is shipping and when it will arrive, all the way through the ordering process.
