Fixed Inductors

Fixed inductors are electronic components in which the inductance value is designed to be very stable in response to temperature, current and frequency changes. A widely used type of fixed inductor is the MLF2012A1R2JT000 from Murata, a leading manufacturer of electronic components. This part is designed to be optimized for use in compact spaces, which makes it an ideal choice for applications in filters and timing circuits.

MLF2012A1R2JT000 Application Field and Working Principle

The MLF2012A1R2JT000 is a 4-terminal, surface-mount, low-profile inductor that has been designed for use in surface-mount devices (SMDs) and fits in a 0.6 mm footprint. It is ideally suited for use in inductor-based active filters, high-speed signal path, timing circuits and power related applications. The MLF2012A1R2JT000 has a typical inductance value of 2.2 μH and a resistance value of 0.51 Ω and is suitable for operating at temperatures up to 125°C.

The MLF2012A1R2JT000 has a ferrite core that consists of grains of the ferrite material which are then interconnected to form a low-resistance path around the winding. The core is wound with either copper-clad aluminum wire for high-frequency response, or enameled copper wire for lower frequencies. The inductance value of the MLF2012A1R2JT000 can thus be especially tailored according to certain design requirements.

The MLF2012A1R2JT000 has a wide operational frequency range of 0.5-400 MHz, which make it suitable for a very wide range of applications. The device is especially well-suited for use in high-frequency circuits, since its small size results in a minimized parasitic losses and reduced component size. The MLF2012A1R2JT000 also has an effective self-resonant frequency, which helps keep the part from ringing or oscillating in high-speed circuits.

The MLF2012A1R2JT000 has a very low DC resistance, which helps boost efficiency by allowing greater current flow. This also helps to reduce energy losses, which is especially useful for applications in which power consumption is a primary concern. The part also has excellent temperature stability, with a maximum temperature coefficient of ±200 ppm/°C, which helps ensure consistent performance and reliability.

The MLF2012A1R2JT000 is an ideal choice for use in a variety of device filters, such as buck and boost converters, high-frequency switching power supplies, Class-D amplifiers, and audio and video signal filtering and conversion. The device\'s very low DC resistance and wide operational frequency range make it suitable for use in various sensitive circuits which require fast system response time, low EMI noise and minimal power dissipation.
