Low dielectric loss: The loss tangent of polypropylene material is very small, which means that the capacitor generates less heat and has high efficiency, making it particularly suitable for high-frequency and pulse circuits.
Good frequency characteristics: stable performance in high-frequency environments, with small changes in capacitance value with frequency.
Good self-healing: Due to the use of metalized thin films, when the dielectric partially breaks down, the metal layer around the breakdown point will instantly evaporate, isolating the fault point and allowing the capacitor to resume normal operation, improving reliability.
Negative temperature coefficient: The capacitance slightly decreases with increasing temperature, indicating good stability.
Polarity free: can be used in AC circuits.
High rated voltage: usually with higher AC and DC rated voltage levels.

CBB20 is a type of "polypropylene film capacitor" and belongs to the subclass of MKP capacitors. And 'core axial' refers to its packaging method - the pins protrude from both ends, making the structure more stable and suitable for high-precision audio filtering circuits.
CBB20 capacitor is known as the "filtering artifact" by Hi Fi DIY players due to its low loss, high stability, and excellent high-frequency response
Especially in frequency division circuits, the use of CBB20 capacitors can significantly improve the clarity and layering of sound, making high notes brighter, mid notes more stable, and low notes cleaner, and the overall listening experience closer to the original sound
Moreover, it has high pressure resistance, long lifespan, and is not easily aged, making it suitable for high-end audio systems
