GC0351P-3

Speakers Overview

The GC0351P-3 is a miniature speaker manufactured by Same Sky, formerly CUI Devices. It features an oval shape with a rectangular frame and measures 16 mm in length, 35 mm in width, and 8 mm in height. The component utilizes a neodymium iron boron magnet and a cloth cone for sound generation. It has a rated power of 1 W and a nominal impedance of 4 Ohms. The self-resonant frequency is specified at 630 Hz, with an operating range extending up to 13 kHz. The sound pressure level is 80 dBA when tested at 1 W/500mm. Electrical connections are made via solder pads, and the unit supports a temperature range from -25°C to +60°C.

Speakers Feature Summary

• Utilizes a neodymium magnet and cloth cone for audio output
• Designed for frame mount installation with solder pad termination
• Compact oval form factor suitable for space-constrained applications

Speakers Applications

• Miniature audio devices
• Portable electronic equipment
• Medical instrumentation

Speakers Procurement Notes

Verify the specific impedance rating of 4 Ohms against circuit requirements, as this variant differs from other models in the series. Confirm that the 1 W power rating aligns with the amplifier's output capabilities to prevent damage. Ensure the operating temperature range of -25°C to +60°C meets environmental specifications. Check for RoHS compliance status if required by project regulations. Validate physical dimensions and mounting style compatibility during integration.

Speakers Selection Notes

Select the GC0351P-3 when a low-impedance 4 Ohm driver is required for the application. This model is appropriate for designs needing a compact oval speaker with a rectangular frame. Consider the 80 dBA sensitivity for volume requirements. Compare with the GC0351P (8 Ohm) or GC0351N (8 Ohm, higher SPL) if impedance or sensitivity needs differ. Ensure the solder pad termination method fits the PCB layout constraints.

Speakers Part Context

The GC0351P-3 belongs to the GC series of miniature speakers from Same Sky. This series includes variants like the GC0351P and GC0351N, which share similar physical dimensions but differ in electrical characteristics such as impedance and sound pressure level. The GC0351P-3 specifically offers a 4 Ohm impedance option within this family, providing design flexibility for different amplifier outputs while maintaining the same compact form factor.

Speakers Replacement Considerations

The GC0351P-3 is a distinct variant within the GC series. Direct substitutes must match the 4 Ohm impedance and 1 W power rating. The GC0351P (8 Ohm) and GC0351N (8 Ohm) are electrically incompatible due to impedance differences. No other public substitute part numbers are confirmed for this specific 4 Ohm configuration.
