• IEC 3.3-5VDC operating voltage compatibility
• Through-hole mounting configuration with PC pins
• Compliance with RoHS environmental standards

Applications

• Perfusion monitoring systems
• Medical equipment audio indicators
• Board-mounted alarm circuits
• Industrial control panel signaling

Procurement Notes

Verify the specific suffix 'HCTPC' against the manufacturer's current datasheet to confirm exact acoustic and electrical specifications. Ensure the ordering documentation matches the required IEC voltage ratings and through-hole pin configuration. Cross-reference the cUL recognition status for IEC60601-1-8 AMD1 compliance if used in regulated medical environments. Confirm RoHS certification status prior to procurement.

Selection Notes

Select this component when a low-profile, internally driven piezo buzzer is required for medical or industrial boards. The 44.45mm diameter suits standard enclosure cutouts. Verify that the 90dB output meets regulatory noise limits for the intended environment. Ensure the PCB layout accommodates the through-hole PC pin spacing and that the driving circuit supports the 15-40mA current draw at 2.075kHz.
