Mundorf MREU30-0,39T1C | 0,39 Ω | 3/30 W | 1%

The Mundorf MREU30-0,39T1C is a precision wirewound resistor engineered for the most demanding audio applications, where signal purity and component reliability are paramount. This 0.39 Ω resistor is ideally suited for use as a current-sensing element in high-end loudspeaker crossover networks, for precise voltage division in power supply circuits, or as a low-inductance emitter resistor in Class A amplifier stages. Its robust construction also makes it an excellent choice for current limiting in valve (tube) amplifier designs, ensuring stable operation under varying loads.

Technically, the component offers a resistance value of 0.39 Ω with a tight tolerance of ±1%, guaranteeing consistent performance across production batches. It is rated for 3 W continuous power dissipation, which can be increased to 30 W when mounted on an adequate heatsink, providing exceptional thermal headroom for high-current applications. The wirewound element is wound on a ceramic core and encapsulated in a non-flammable coating, delivering low inductance and excellent long-term stability. This Mundorf resistor is a premium solution for audiophiles and engineers who demand the highest level of accuracy and sonic transparency from their passive components.
