AS03604MR-N50-HT-R

Overview

The AS03604MR-N50-HT-R is an electromagnetic speaker manufactured by PUI Audio, Inc. It features a round shape with a diameter of approximately 36 mm and a height of roughly 12 mm. The unit operates at a nominal impedance of 4 Ohms and has a rated power handling capacity of 3 Watts. Its self-resonant frequency is specified at 200 Hz, delivering a sound pressure level of 85 dB. The component utilizes Neodymium Iron Boron (NdFeB) magnet material and a Mylar cone. It supports panel mounting and is designed for operation within a temperature range of -40°C to +85°C.

Feature Summary

• Utilizes high-strength Neodymium Iron Boron magnetic structure for efficient audio output
• Constructed with durable Mylar diaphragm material for consistent performance
• Engineered for robust thermal stability across extended industrial temperature ranges
• Designed for secure panel mounting applications in compact enclosures

Applications

• Industrial control panels requiring audible status indicators
• Medical equipment providing user feedback signals
• Consumer electronics housing needing reliable acoustic alerts
• Security systems utilizing tone generation for alarms

Procurement Notes

Verify the specific suffix HT-R against official PUI Audio documentation to confirm high-temperature rating and RoHS compliance status. Ensure mechanical dimensions align with panel cutout requirements before procurement. Cross-reference the 4-ohm impedance and 3-watt power rating with system drive capabilities to prevent overload. Confirm availability through authorized distributors as manufacturing lead times may vary based on current production schedules.

Selection Notes

Select this model when a compact, high-output speaker is required for environments with elevated temperatures. The 4-ohm impedance suits low-voltage driver circuits common in portable devices. Compare the 85 dB sensitivity against noise floor requirements of the target application. Consider the physical depth constraint of approximately 12 mm for tight enclosure designs. Evaluate the Mylar cone durability against potential environmental exposure conditions.

Part Context

This component belongs to PUI Audio's general-purpose speaker lineup, specifically engineered for broad commercial and industrial use. The manufacturer specializes in custom and standard audio solutions including transducers and sirens. This particular series emphasizes reliability and acoustic efficiency within small form factors, catering to designers needing dependable sound generation without complex amplification stages.

Replacement Considerations

Direct substitutes must match the 4-ohm impedance, 3-watt rating, and similar physical footprint. Verify that alternative speakers maintain comparable sensitivity levels around 85 dB. Ensure replacement units support the same operating temperature range if deployed in harsh environments. Check terminal configuration compatibility for panel mounting integration.
