Ultra Small SMD Electromagnetic Buzzer
The Ultra Small SMD Electromagnetic Buzzer is a compact surface‑mount device that operates between 2,000 Hz and 4,000 Hz and delivers a sound pressure level of 75 - 95 dB at 10 cm. It is built from a copper coil, steel diaphragm, ABS housing and a rare‑earth magnet and complies with RoHS lead‑free requirements. Rated voltage is 3.0 Vpp while the permissible operating voltage range is 2.0 - 4.0 Vpp, with a current draw of 110 mA at the rated point. The coil resistance measures 12 Ω ± 2 Ω and the component tolerates temperatures from - 20 °C to +85 °C in operation and - 30 °C to +85 °C in storage.
The use of LCP for the housing gives the buzzer heat resistance and acid‑alkali resistance, while yellow‑grass lead pins improve solderability during SMT assembly. Such material choices match industry practice for ultra‑small acoustic transducers that must fit tight PCB real estate and survive repeated thermal cycles. Typical SMD buzzers of this class are supplied in tape‑and‑reel format and mounted with a 0.5 mm lead pitch, which aligns with standard pick‑and‑place equipment. The design targets high‑reliability applications where space constraints and consistent acoustic output are critical.
Common applications include warning tones in smartphones, tablet accessories, Bluetooth devices, automotive dashboards, IoT terminals and medical instrumentation. Buyers such as original equipment manufacturers and contract assemblers value the consistent SPL and the narrow audible distance of 0.5 - 1 m at rated voltage. The supplier indicates flexible ordering quantities but does not disclose a minimum order, so importers should confirm the MOQ and lead time directly. Standard trade terms follow typical electronic component sourcing, with payment and Incoterm details to be negotiated per order.

Sourcing Ultra Small SMD Electromagnetic Buzzer from Changzhou Keliking Electronics Co., Ltd. - China Import Guide
Before confirming a purchase, verify that the buzzer’s frequency, SPL and voltage ratings match the requirements of your end product and that the RoHS certificate is up to date. Cross‑check the supplier’s address in Changzhou and request a recent factory audit report to confirm the manufacturing environment. Obtaining a functional sample and a test report for coil resistance and current consumption will reduce the risk of integration issues.
Discuss logistics early; typical lead times for custom‑size SMD buzzers range from two to six weeks, but the exact schedule must be confirmed with the supplier. Agree on Incoterms such as FOB Changzhou or CIF your destination port, and clarify who arranges freight forwarding and insurance. Payment terms are usually a 30 % advance letter of credit with the balance payable against inspection or document presentation.
Arrange a pre‑shipment inspection that checks visual solderability, dimensional conformity and acoustic performance against the specified SPL. A third‑party lab can validate the 75 - 95 dB output and the 110 mA current draw under rated voltage. Ensure the shipment is accompanied by a test certificate, RoHS declaration and a packing list that details reel quantities and handling instructions.
