Fixed inductors are a type of electrical components used in a wide variety of circuits. They are commonly found in applications such as power supplies, filter circuits, and oscillators. The CDH2D09SNP-2R4MC is a specific type of fixed inductors used as dual-layer wound components, providing high-frequency characteristics for power supplies and filter circuits. ConstructionThe CDH2D09SNP-2R4MC fixed inductors consist of two copper wires wrapped in around an iron-core magnetic cylinder. The coil and the magnetic core are enclosed in a resin-case and wrapped in a sealed package. This ensures that the component is highly durable and resistant to shock, vibration, and temperature variation. The magnetic core ensures that the inductance is consistent across the operating range and provides a high saturation current. Working PrincipleThe fixed inductors work on the principle of magnetic induction. When an alternating current (AC) is passed through the inductor, an electromagnetic field is created around it. This field of magnetic flux induces current in the second coil, which can be either obtained as DC current or returned back to the source as AC current. The magnitude of the inductance is determined by the number of windings and the permeability of the core. CharacteristicsThe CDH2D09SNP-2R4MC fixed inductors are usually rated for a maximum current of 1.5A, and a high rated current of 4A.The operating temperature range they can work in is between -40°C to +85°C, and their rated voltage ranges from 13V to 630V. They have a distributed capacitance of 0.0015 µF, and a frequency range of 30-500kHz. The self-resonance frequency is 1.2MHz and the inductance value is 2.4mH. Applications The CDH2D09SNP-2R4MC fixed inductors are used mostly in DC/DC converters, voltage regulators, and power supplies. The high resistance to shocks and temperature variation makes them the perfect choice for applications with high-vibration levels. They also find applications in filter circuits and oscillators, high frequency circuits, portable appliances, and medical devices.
