Series RT
AudioCap Polystyrene-&-Tin Foil RT

The RT series AudioCap offers very high insulation resistance, with the lowest dielectric absorption and dissipation factor available, and low temperature coefficient. It has excellent stability and retrace, making this an ideal capacitor for all applications in audio except those with extremely high operating temperatures. In performance, it is second only to the MultiCap polystyrene (RTX) and the AudioCap Teflon (TFT), and makes a particularly good bypass cap, providing added performance in the upper frequencies. It is suitable for ultra-high frequencies, and will provide high performance and long-life; the gold-plated OFHC leads provide long-term reliability, superior to silver wires owing to gold�s non-oxidizing properties.
