FAQ
Frequently Asked Questions
Q: What is the operating temperature range of this buzzer?
The operating temperature range is typically -20\u2103 to +70\u2103, ensuring stable sound output in automotive and industrial environments.
Q: How to choose between self-drive and external-drive versions?
Self-drive (internal driver) types sound as soon as DC power is applied; external-drive types need a drive signal around 2000-4000Hz from your circuit. Our engineers will help you select the right type.
Q: What certifications do these buzzers comply with?
Our products are manufactured under ISO 9001 and are available with CE, RoHS, FCC and EMC certifications. Certification documents are provided on request.
