Fixed inductors are electronic components with stable inductance. They are mainly used in signal and power circuits of electronic products for filtering, oscillating, resonating, storing, transforming and suppressing interference. Free-wheeling diodes, snubber emitters, chokes, adjustable inductors and transformers are all classified as fixed inductors. The DR125-221-R is a mains transformer inductor with self-recovering axial dielectric which enables it to specifically meet all mains standards, especially IEC 62040-3 2V2.The DR125-221-R is particularly suitable for CD power supplies, converters, power supplies for LED lighting, switching power supplies, SMPS (switched mode power supplies) and high-frequency apps such as DC-DC converters. It is used in AC/DC and DC/DC converter applications and it is also very useful for a range of portable applications such as computers, smartphones, tablets, adapters, chargers and more.This inductor is provided with a self-recovering dielectric with a power factor of 0.99. It has a turn-to-turn ratio of 0.6, a maximum operating frequency of 300 kHz, an insulation resistance of 5 MΩ and a dielectric strength of > 500V AC. In addition, the DR125-221-R has a range of efficiency, noise reduction and EMC immunity features.The DR125-221-R works by providing high efficiency to minimize losses due to heat and better regulate voltage and current. The self-recovering dielectric allows for a softer and more reliable pulse, run and start function, which results in better protection and regulation of the circuit. This also helps to reduce electromagnetic interference, allowing for safer and more precise operation.The DR125-221-R further includes a model with two wires to allow for more efficient connection and wiring of the inductor. It has a ferrite core that provides excellent core loss and encourages higher temperature stability, even when heated due to continuous operation. This helps to guarantee a longer life for applications where high temperature is a concern.Overall, the DR125-221-R is an excellent fixed inductor which is particularly suitable for many applications, ranging from CD power supplies to LED lighting and portable devices. It is also designed to work safely and reliably in environments with high temperature requirements, and it is provided with a self-recovering dielectric to ensure protection and regulation of the circuit.
