Frequently Asked Questions

What is the difference between self-drive and external-drive buzzers?

Self-drive buzzers have an internal oscillator and only require DC voltage to operate. External-drive buzzers need an external square wave signal to generate sound, offering more control over frequency and duty cycle.

Are your products RoHS compliant?

Yes, all our components are lead-free and fully compliant with RoHS and other international environmental standards.

Can you customize buzzer frequency or voltage?

Absolutely. We offer full customization for resonant frequency, operating voltage, sound pressure level, and physical dimensions to meet your application requirements.

What is the minimum order quantity (MOQ)?

MOQ varies by product type and customization level. Contact us for sample availability and volume pricing.
