EI Type Audio Transformer 20Hz-20kHz with Frame and Lead Wire for Telecom and Audio Equipment
Audio Transformers
This EI-type audio transformer features a frame lead structure. Frequency range is 20Hz to 20kHz. Impedance is 20KΩ:600Ω. Maximum output is 75mW. Insulation resistance: >10MΩ @100VDC. Withstand voltage: 100VAC/1 minute. Frequency response: ±3dB (300Hz-3.4kHz @1kHz 0dB). The transformer is treated with vacuum wax impregnation. PC leads are soft metal wire that can be adjusted to suit various applications. It supports water washing processes with water temperature below 20°C. It is widely used in audio systems, telecom isolation, SMD fax modems, and PCMCIA applications.
