SD20C-330-R

Fixed Inductors are important components of a variety of different electronic applications, and the SD20C-330-R is one example of an inductor that is widely used in many industries. The product is a surface-mountable inductor, and this article will discuss the application field and working principle of the SD20C-330-R.

Application Field

A wide variety of applications make use of the SD20C-330-R. It is used to provide a conductor in power supplies, switching power supplies, DCDC converters, amplifiers, and DC-AC inverters. It is also frequently found in embedded systems, such as automotive, consumer electronic, and communication applications. This inductor also functions as a filter inductor in flyback converters.

SD20C-330-R inductors are particularly well suited for harsher industrial applications due to their excellent surge current vs. self-resonance frequency ratio, their higher operating temperature range, and their high heat resistance. This makes them a great choice for applications for which reliability is key.

Working Principle

The SD20C-330-R employs a core of magnetic material that is made up of a coil and a bobbin. The coil is made up of multiple turns of a wire, usually made of copper, wound around the core in a specific configuration. The bobbin is usually made of plastic, and is used to hold the coil in place. The core is then surrounded by a magnetic field, which is produced by an external electromagnet or by an electrical current passing through the coil.

When a current is passed through the coil, it causes electrons within the coil to move in circles around the core, creating an electromagnetic field. This field is what induces a voltage across the wire, which is then used to power the circuit. In a typical application, when the current is passed through the coil it induces a voltage, which then causes a current to flow back through the coil in the opposite direction.

The SD20C-330-R performs better than other inductors due to its higher surge current vs. self-resonance frequency ratio. This means that it is able to more effectively store and release energy, which gives it better performance than other inductors in terms of efficiency and reliability.

The SD20C-330-R is an effective and reliable inductor that is suitable for a wide range of applications. Its high surge current vs. self-resonance frequency ratio, high operating temperature range, and high heat resistance make it an excellent choice for harsher industrial applications where reliability is key.
