The UP4T-151-R is classified as a fixed inductor, which are components that are capable of storing energy in the form of a magnetic field and discharging it when required. The device usually comprises of a conductor (such as a coil of copper wire) wrapped around a magnetic material (such as ferrite, iron, etc.). In its most basic form, the basic principle behind an inductor is a constant current passing through the coil of wire, creating a magnetic field around the conductor. This magnetic field stores energy, so when the current on the coil changes, the magnetic field will also change, inducing a voltage in the coil. This voltage can be used to provide power to an external circuit, when required. The UP4T-151-R is an inductor that has been designed by Pulse Electronics to provide inductance values up to 181nH, and with DC resistance values of 10 ohms. The device works through an exact combination of size and a wide range of wire gauges, allowing for the precise inductance value to be achieved. The UP4T-151-R is typically used in applications where stable inductance values and low voltage drops are required, such as in low-noise power supplies, flat panel televisions, and radio devices. The device features an extended operating temperature range of -40 degrees Celsius to +85 degrees Celsius, making it suitable for applications that experience extreme temperatures. The UP4T-151-R also includes the Pulse Electronics’ patented “Square-Varistor” construction, which features a low profile coil, with a plastic bobbin providing support and strain relief for the wires. This construction allows for a much more precise level of inductance control, and ensures that the device can reliably operate in the temperatures that it is expected to. In summary, the UP4T-151-R is a fixed inductor that is designed to provide a predictable level of inductance, and maximum reliability in extreme temperatures. The component is suited to applications that require low voltage drops, such as in power supplies and televisions. The device also includes Pulse Electronics’ patented “Square-Varistor” construction, which allows for a much more precise level of induction control.
