The YB41F3-30A-S EMI Filter, with a rated voltage of 115V/250V and a rated current ranging from 20A to 200A, operates effectively in environments with temperatures up to 40°C. It boasts a wide temperature range of 25°C to 85°C, making it suitable for various applications. This filter operates at frequencies of 50/60Hz, providing robust performance. With a line-to-line voltage of 1450VDC and a line-to-ground voltage of 2250VDC or 2000VAC, it ensures reliable electrical isolation. It meets stringent industry standards with certifications including cUL, ISO9001, CE, CQC, ROHS, and TU. This EMI filter, designed with a low pass transfer function, delivers an insertion loss of 30 to 60dB, effectively attenuating unwanted noise. Its nominal center frequency ranges from 10kHz to 30MHz, with a 3dB bandwidth of 14K. With an input impedance of 50Ω and a stopband attenuation of 20 to 100dB, it provides exceptional performance and reliability for your application needs.
