Fixed inductors are electronic components that store energy in the form of a magnetic field when current is applied. The PTHF25R-30SM is one type of fixed inductor that is widely used in applications such as filters, power supplies, and antennas. It is also well-suited for use in high-frequency circuits due to its great temperature stability and low losses.

The PTHF25R-30SM is a 100% surface mount and radial leaded inductor with a 2.2 uH rating. The inductance remains consistent over a frequency range of 0.3 MHz to 30 MHz and is suitable for use in digital, low-loss DC-DC converter loops. It is also available in an extended temperature range of -40 degrees Celsius to +105 degrees Celsius, making it ideal for automotive, defense, and telecom applications.

The PTHF25R-30SM’s construction is based on an integrated magnetic core and winding design. This allows for a small and compact form factor, making the inductor ideal for applications that need to conserve space. The device is also constructed of corrosion-resistant material and has a superior moisture-resistant coating, which allows it to tolerate harsh environments reliably.

The working principle of the PTHF25R-30SM is based on Faraday’s law of induction. It states that when a changing current is applied to a conductor, an electromotive force (EMF) is created. This EMF, in turn, induces a secondary current that flows in the opposite direction of the primary current. The magnitude of this secondary current is determined by the amount of inductance in the conductor.

As current passes through the PTHF25R-30SM inductor, a magnetic field is established in the core. This magnetic field stores energy and, when the current is removed, liberates it slowly, allowing for a controlled energy discharge. The energy stored and released from the magnetic field is proportional to the inductance of the device and the number of turns in the winding. This provides an important part of the inductor’s ability to reduce electromagnetic interference (EMI) in its application circuits.

The PTHF25R-30SM is a popular choice for designers due to its superior temperature stability, low losses, and low cost. It is used in a wide variety of applications including filters, power supplies, antennas, DC-DC converters, and much more. With its great performance, reliability, and small form factor, the PTHF25R-30SM is a great choice for most electronic projects and applications.
