Product Description

OEP Z30A18C Through Hole Audio Transformer is engineered with precision to deliver superior audio signal isolation and minimal distortion. This Audio Transformer features a high primary impedance of 600Ω and primary DC resistance of 36.4Ω, making it ideal for line or microphone input applications. The enclosed construction includes a mumetal screening can that effectively reduces electrical noise by up to 30 dB and uses a stray flux copper band along with electrostatic screens to provide enhanced noise suppression and galvanic isolation.

Its wide operating frequency range of 10 Hz to 30 kHz and maximum isolation voltage of 1000V make the Z30A18C suitable for a variety of professional audio environments. The transformer employs PC pin termination and through hole mounting for straightforward installation on printed circuit boards. Operating temperatures range from -20°C to 70°C, ensuring reliable performance in diverse ambient conditions.

The compact physical dimensions (36 mm length, 30 mm width, 16 mm depth) and light weight (45 g) allow integration in space-constrained applications. Common industrial and commercial use cases include audio line inputs, microphone interfaces, ground loop isolation, low distortion circuit designs, and phono stage inputs in professional audio equipment, broadcast hardware, and instrumentation.

Features mumetal shielding for electrical noise reduction up to 30 dB. Includes stray flux copper band and electrostatic screens for superior isolation. Galvanic isolation and low distortion characteristics ensure clean audio signal transmission.

Wide frequency response ranging from 10 Hz to 30 kHz for fidelity across audio bands. Robust through hole mounting and PC pin termination support reliable PCB installation. Durable performance across temperatures from -20°C to +70°C environment.

Compact design suits industrial, laboratory, audio production, and broadcast applications. Enclosed construction provides protection and consistent performance in demanding conditions.
