Fixed Inductors

Fixed inductors are designed to provide an inductance, which does not vary with frequency, current, or any other external variable. Fixed inductors come in a variety of shapes and sizes, from large package types for high leakage inductors, to miniature surface mount components with very low profiles.

PM1608-100M-RC

The PM1608-100M-RC is a fixed inductor that is commonly used in a variety of applications that require an inductance of 100 microhenries. It’s a surface mount device, just 12.8 x 11.2 x 5.84 mm in size. It can withstand a maximum current of 4.75 amps and can operate in temperatures ranging from -40 to 85°C.

Application Fields

The PM1608-100M-RC can be used in a wide range of applications, such as:

• Switching power supplies and transformers
• Noise suppression circuits
• RF circuits
• Low ESR bypass circuits
• High frequency resonant circuits
• DC-DC converters

Working Principle

The working principle of the PM1608-100M-RC is based on Faraday\'s Law of Induction, which states that “when the magnetic flux through a circuit changes, an electromotive force (EMF) is induced in the circuit”. This induced EMF will oppose the original cause of the flux change and is quantified when we calculate the inductance of the inductor.

The core material used in the PM1608-100M-RC is ferrite, a type of ceramic material. The ferrite core has two plates, one on the top and one on the bottom, with the winding in between. The magnetic field generated by the AC current passing through the windings induces an EMF in the coil, which opposes the original current, resulting in an inductance value of 100 microhenries.

The inductance is determined by the number of windings, length, diameter and core material used. The PM1608-100M-RC contains five turns of 28 AWG magnet wire wound on a ferrite core and has a wound coil diameter of 8.0 mm.

The PM1608-100M-RC fixed inductor is a reliable and cost-effective solution for applications that require an inductance of 100 micro-henries or less. It’s a surface mount device with low profile, small size and low cost, making it an ideal choice for switching power supplies, RF circuits, noise suppression circuits and low ESR bypass circuits.
