Fixed inductors are a type of electronic components used to create inductive electrical circuits. They are used to smooth out any voltage fluctuations in a circuit, regulate current flow, reduce radio frequency interference, set up resonant circuits, and other tasks. Most common fixed inductors are formed from a coil of wire with an iron core running through it. This core can be made of ferromagnetic material such as iron or steel.

The 511R-48H is a type of fixed inductor produced by Bourns Incorporated designed for use as an electromagnetic choke in DC power supplies, automotive audio systems, and appliances. The 511R-48H is a single-in-line package (SIP) inductor and is characterized for its lead-free construction, ability to dissipate heat quickly, low-leakage, and high-saturation current capabilities.

The 511R-48H can be used in a variety of electronic circuit applications, but is primarily designed for use in DC power supplies. When used as an electromagnetic choke, it prevents unwanted current from flowing back into the power supply, creating a stronger, more consistent DC output. This makes the 511R-48H a great choice in automotive sound systems, appliances, and other electronics where a stable DC power supply is important.

The 511R-48H is constructed from a core material, typically an iron-silicon alloy. The core is then wrapped with copper wire that’s magnetically insulated to prevent short-circuiting. The copper wire helps increase the choke\'s inductance while decreasing its resistance to current flow.

In operation, the 511R-48H will limit the current flow entering the circuit. This happens because current creates a magnetic field which then induces current in the opposite direction, reducing the amount of current that can pass through the inductor. The amount of current that is restricted depends on the inductance of the coil and the frequency of the current.

The 511R-48H has a wide operating temperature range of -55°C to +125°C and can endure spikes up to 3A at 300 kHz for a period of 10ms. It is also rated at up to 100mH of inductance and has a maximum DC resistance of 39 ohms.

Overall, the 511R-48H is a well-rounded fixed inductor suited for applications requiring high-power and high-saturation current capabilities. With its lead-free construction and ability to dissipate heat quickly, it is an excellent choice for DC power supplies and other electronic circuits where a reliable power source is required.
