Overview
The UDB05BILFPH is an internally driven magnetic buzzer manufactured by DB Products. It operates at a nominal voltage of 5 V with a current consumption of 30 mA. The device produces an acoustic output of 85 dB measured at a distance of 10 cm when powered at 5 V. The operating frequency is specified as 2.7 kHz. This component utilizes through-hole PC pins for mounting and is designed for direct integration into electronic circuits requiring audible signaling.
Feature Summary
- Internally driven magnetic transducer design
- Through-hole PC pin mounting configuration
- High acoustic output level capability
Applications
- POS systems
- Banking and ATM equipment
- Time and parking equipment
Procurement Notes
Verify the specific suffix LFPH against official DB Products documentation to confirm lead-free compliance and packaging details. Ensure the 5 V rating matches the target circuit supply voltage. Confirm that the 30 mA current draw is within the driving circuit's capacity. Validate the 85 dB acoustic requirement against application noise floor specifications before finalizing procurement.
Selection Notes
Select this component when an internally driven solution is required to simplify driver circuitry. The 5 V operating voltage suits standard logic-level power supplies. The high sound pressure level makes it suitable for environments with moderate ambient noise. Verify physical dimensions and pin spacing compatibility with the printed circuit board layout during the design phase.
Part Context
DB Products specializes in acoustic components, including buzzers, piezo elements, and microphones. The UDB05BILFPH belongs to their range of magnetic transducers designed for reliable audible signaling. The company has supplied these components globally since 1976, focusing on integrating human hearing sensations with electronic technology for various industrial applications.
Replacement Considerations
Consult official DB Products substitution guides for verified equivalents. Ensure replacement parts match the 5 V operating voltage, 2.7 kHz frequency, and 85 dB acoustic output. Verify mechanical compatibility regarding through-hole pin configurations and overall dimensions.
