Overview
The DB Products 187PZ17400LFMP is an externally driven magnetic transducer designed for signal indication applications. It operates with a peak-peak signal input and supports a normal voltage rating of 12 V, with a maximum range of 25 V. The device functions at a frequency of 4 kHz. It is manufactured by DB Products Limited, a Hong Kong-based specialist in acoustic components. The component is currently active and utilizes surface mount technology for installation. It is suitable for environments requiring robust acoustic signaling within specified thermal limits.
Feature Summary
- Externally driven magnetic transducer design
- Surface mount installation style
- Operates at 4 kHz frequency
- Supports 12 V normal voltage with 25 V maximum limit
Applications
- Signal indication systems
- Buzzer and siren assemblies
- Acoustic alerting devices
Procurement Notes
Verify the specific package dimensions and pin configuration against the manufacturer's datasheet to ensure compatibility with the target PCB layout. Confirm that the driving circuit can provide the required peak-peak signal amplitude without exceeding the 25 V maximum rating. Ensure the operating environment remains within the -40°C to +85°C temperature range to maintain performance integrity and longevity of the acoustic component.
Selection Notes
Select this component when an externally driven magnetic solution is required for 4 kHz acoustic signaling. Consider the surface mount form factor for automated assembly processes. Evaluate the driving circuitry capabilities to match the 12 V nominal requirement. Compare against self-drive piezo alternatives if internal oscillator functionality is preferred over external signal generation.
