The NVE-05 is specialized in countermeasures against such high-frequency noise, and arranges film capacitors with excellent high-frequency characteristics by capacitance (reducing high-frequency impedance) to suppress and attenuate noise generated by inverters, switching power supplies, internal clocks, etc
 
Until now, power filters for car audio were mainly formed by composite circuits with high-capacity electrolytic capacitors and choke coils. These have contributed significantly to battery voltage fluctuations and relatively low (noise) frequency bands. Battery voltage fluctuations affect the stable operation of automotive electronic devices, and have a significant impact on sound quality in car audio equipment. This is still a continuous market need. On the other hand, in recent years, the automobile industry has seen a wave of hybrids and EVs. Various control electronic devices installed in vehicles, including car audio equipment, are becoming more digital, and the interior of the car is flooded with various high-frequency noises.
