Procurement Notes
Verify the specific suffix (NS2) against official Raltron documentation to confirm exact acoustic and electrical tolerances. Ensure the ordering information matches the required package style and compliance certifications. Cross-reference the datasheet for precise mechanical drawing details before finalizing procurement specifications.
Selection Notes
Select this component for applications requiring a low-profile audible indicator in space-constrained designs. The 3 VDC operating voltage aligns with standard logic levels, while the 70 dB output ensures audibility in moderate noise environments. Confirm that the external driver circuit can supply the required 90 mA current peak.
Part Context
This part belongs to the RDTE series of magnetic buzzers from Raltron Electronics. The series offers various sizes and frequencies, with the NS2 suffix indicating specific packaging or compliance attributes. These components are designed for integration into portable and stationary electronic devices requiring reliable audio signaling.
Replacement Considerations
Direct substitutes include other 4 kHz, 3 VDC surface-mount magnetic buzzers with similar dimensions. Verify pinout compatibility and acoustic output levels. Check for equivalent current requirements and mounting hole patterns if mechanical constraints are strict.
