Technical Specifications:

Detailed technical specifications for the TG-4OP-0323-20, such as inductance, impedance, rated current, and DC resistance, would typically be found in the product datasheet. Key parameters include the inductance value (in Henries), which determines the choke's effectiveness at different frequencies; the impedance (in Ohms) at specific frequencies; the rated current (in Amperes), which specifies the maximum current the choke can handle without saturation; and the DC resistance (DCR), which affects power loss. Other important specifications include the operating temperature range, insulation resistance, and the choke's physical dimensions. The core material (typically ferrite) also plays a critical role in its performance characteristics.
