KPE-276 – KINGSTATE

The KINGSTATE KPE-276 is a passive piezoelectric buzzer element supplied on reels, manufactured in 2006, and predates Restriction of Hazardous Substances (RoHS) directives. This component is designed for through-hole mounting and requires an external driving circuit to generate an audible tone. Its resonant frequency and sound pressure level (SPL) characteristics are contingent upon the specific driving frequency, voltage, and enclosure design employed. Given its 2006 manufacturing date and non-RoHS compliance, the KPE-276 likely contains lead (Pb) and other restricted substances. Electrical characteristics, such as capacitance and impedance at resonance, are not specified, necessitating empirical evaluation for optimal circuit integration. The reel format facilitates automated assembly processes, though careful consideration must be given to storage conditions to prevent degradation of the piezoelectric material and solderability issues due to oxidation.
