Fixed inductors are widely used in the fields of power electronics, electric power, electric motor, communication, telecommunications, audio-visual products, computer peripherals and defense industry. SDR2207-390KL is a new type of fixed inductor developed by the well-known American brand Pacific Analog. This powerful miniature inductor features a high inductance value with low electrical noise, excellent inductance retention with frequency, and wide operating temperature range. It is suitable for applications such as switching power supplies, DC-DC converters, and EMI/RFI filters.

The SDR2207-390KL is a shielded inductor transceiver designed with two shielding layers of heavy gauge copper. Each layer is coated with a high melting point polycarbonate which provides very good shielding against RF emissions. The inductance of the SDR2207-390KL is rated as 390 microhenries, with a DC current range of from 0.3 to 10 amps. Its rated frequency range is from 10Hz to 500kHz, and with the low electrical noise rating of ±0.5%, it is perfect for use in high frequency applications. It is also rated for a very wide operating temperature range of -40°C to +125°C.

The SDR2207-390KL works on the principle of induction. When current flows through the coil of the inductor, a magnetic field is created around the coil. This magnetic field opposes the change in current, causing an induced EMF to be generated in the coil, and a corresponding voltage drop across the device. This is known as inductive voltage drop, and it is what limits the amount of current and voltage that can be supplied to a specific load.

The SDR2207-390KL is a perfect choice for applications such as power supplies, DC-DC converters, and EMI/RFI filters. It can handle high current and voltage levels with a low level of electrical noise. It is also durable, with a wide operating temperature range and excellent inductance retention with varying frequencies. For these reasons, the SDR2207-390KL is an ideal choice for many high-frequency applications.
