Dayton Audio DPR20-30 | 30 Ω | 20 W | 1%

The Dayton Audio DPR20-30 is a precision audio grade bifilar resistor offering a resistance of 30.0 ohms, a power rating of 20 watts, and a tolerance of ±1%. Designed for the most demanding signal-path applications, this component ensures exceptional accuracy and consistency in high-fidelity audio circuits. Its robust construction makes it an ideal choice for achieving precise channel balancing in stereo amplifiers, crossover networks, and other critical audio systems where even minor impedance variations can degrade sound quality.

This resistor excels in use cases requiring low inductance and high power handling, such as in loudspeaker crossover designs, power supply filtering, and output stage loading. The bifilar winding technique minimises parasitic inductance, preserving signal integrity across a wide frequency range and making it particularly suitable for high-end audio projects where clarity and detail are paramount. Whether you are building a custom amplifier or upgrading existing equipment, the DPR20-30 delivers reliable performance.

Technical features include a non-inductive bifilar winding on a ceramic core, which reduces electromagnetic interference and ensures stable operation under load. The ±1% tolerance guarantees tight matching between channels, while the 20-watt power rating accommodates demanding applications without overheating. The resistor is finished with a durable coating for long-term reliability.

In summary, the Dayton Audio DPR20-30 combines precision engineering with robust construction, making it an essential component for audiophiles and engineers seeking uncompromising sound quality in their designs.
