TC55FD00-08

Overview

The TC55FD00-08 is a full-range speaker driver manufactured by Peerless by Tymphany. It features a 1-3/4 inch (44 mm) paper cone with a polyurethane surround and a steel basket construction. The unit utilizes a ferrite magnet motor assembly equipped with a copper cap to reduce inductance distortion. Key electrical parameters include a nominal impedance of 7.17 Ohms, an RMS power handling capacity of 5 W, and a sensitivity rating of approximately 77.3 to 78.7 dB. The frequency response spans from 200 Hz to 20 kHz, with a self-resonant frequency (Fs) of roughly 180 Hz and a total Q factor (Qts) of 1.2.

Feature Summary

• Paper cone diaphragm with polyurethane surround for balanced acoustic performance
• Ferrite magnet motor system integrated with a copper cap to minimize inductance modulation
• Robust steel basket frame providing structural stability
• Full-range configuration suitable for direct radiating applications

Applications

• Compact consumer audio devices requiring small form factors
• Portable personal audio equipment
• Low-cost multimedia speakers
• Replacement drivers in existing enclosed audio systems

Procurement Notes

Verify the specific datasheet version when ordering, as sensitivity and impedance values may vary slightly between production batches or regional specifications. Confirm that the square frame dimensions match the intended enclosure cutout requirements. Ensure compatibility with the target amplifier output impedance, noting the 7.17 Ohm nominal rating differs from standard 8 Ohm conventions. Check RoHS compliance status if required for specific regulatory markets.

Selection Notes

Select this component for designs prioritizing compact size over low-frequency extension due to its high Qts and resonance frequency. The paper cone material offers distinct tonal characteristics compared to synthetic alternatives. Consider the 5 W power limit when designing for high-volume environments. The square frame geometry allows for efficient packing in rectangular enclosures but requires precise mounting hole alignment.

Part Context

This driver belongs to the Peerless by Tymphany full-range series, which focuses on cost-effective solutions for mass-market audio products. The brand leverages vertically integrated manufacturing across Asia, Europe, and the USA to maintain quality control. This specific model represents a standard offering in their portfolio of transducers ranging from 8mm to 18 inches, targeting volume-driven consumer electronics segments.

Replacement Considerations

Direct substitutes must match the 44 mm diameter, square frame footprint, and 7.17 Ohm impedance. Verify that alternative drivers possess similar Fs and Qts values to maintain the original acoustic tuning. Ensure the replacement maintains the same mounting screw pattern and magnetic structure height to fit existing chassis constraints without modification.
