Fixed Inductors

Inductors are two-terminal electrical components that are typically used to store and control the flow of electric current through a device or system. They are commonly found in circuits providing reactive components like filters or protective devices. The DC630-274K is a type of fixed inductor, used in applications such as power supplies, voltage regulators and signal control circuits. In this section, we will discuss the features, application field and working principle of the DC630-274K.

Features

The DC630-274K combines high electrical power density, low leakage, low temperature coefficient and low insertion loss for optimal signal control in electrically noisy environments. The device consists of an aluminum housing with an epoxy core structure, allowing for good temperature dissipation. Its common mode inductance (Lcm) is a low 0.25 uH, with a DC resistance (Rdc) value of 0.01 ohms. Its capacitance is also noteworthy, at 18 pF.

Application Field

Due to its excellent electrical performance and heat dissipation, the DC630-274K is ideal for a wide range of signal control applications. These include line beam diode and electrostatic beam deflectors, high-frequency electronics switching, power amplifiers, musical instruments and even medical electronics and imaging.

Working Principle

Being a fixed inductor, the DC630-274K functions by creating an opposing electric current when a voltage is applied across its terminals. This opposing current helps to suppress unwanted electric noise and harmonics from the main current while maintaining the desired signal control. The inductor’s core is wrapped in an epoxy sheath, helping to reduce its temperature coefficient and thus maintain its accuracy. It also benefits from its low leakage and capacitance, making it a reliable choice for signal control in electrically noisy environments.
