Fixed inductors, also known as chokes, are electronic components made from coils of wire. The CW201212-4N7J is a fixed inductor designed specifically for use in power supplies, allowing current to flow freely in one direction while blocking current in the opposite direction. This unique design offers protection from power surges, and its light weight construction makes it ideal for applications where space is tight.

The CW201212-4N7J is a four-terminal, 7-turn inductor, with an inner diameter of 20 mm, and an outer diameter of 24 mm. It contains two metal-alloy, windings which are immersed in an epoxy-shaped potting material. The two windings, Red and Blue, act as two individual inductors connected together in series. This series arrangement provides a high degree of voltage isolation between the two windings, allowing them to be used in circuits with very high voltages.

The CW201212-4N7J operates according to Faraday’s Law of Induction which states that when a wire carrying an electric current is subjected to a changing magnetic field, a voltage is induced in the wire. When the CW201212-4N7J is connected to a power source, current travels through the Red winding in one direction, generating a magnetic field. This magnetic field induces a voltage in the Blue winding, the magnitude of the voltage depending on the strength of the magnetic field. The magnitude of the magnetic field is determined by the amount of current passing through the Red winding, allowing the inductor to regulate the amount of voltage passing through the Blue winding.

The CW201212-4N7J has a wide range of applications in power supply circuits, such as voltage regulators, inverters, and display systems. When used in a voltage regulator, the inductor is connected to the power supply, allowing current to freely flow in one direction while blocking current in the opposite direction. This helps to prevent short-circuiting and avoids damage to the power supply. The device can also be used in inverters to filter AC ripple, and in display systems to reduce the amount of power consumed by the display.

The CW201212-4N7J is designed to meet the strict quality standards of the electronic components industry. It has an operating temperature range of -40°C to +125°C, and an insulation resistance level of 500MΩ (min) at 500V DC. In addition, it offers long-term reliability and is protected against dust, moisture, and other environmental factors.

The CW201212-4N7J is an ideal solution for applications requiring a reliable and highly efficient power supply circuit. With its four-terminal design, high voltage isolation, and easy-to-install construction, it is well-suited for a wide range of electronic components applications. It offers outstanding performance and is an excellent choice for power supplies, inverters, and display systems.
