Fixed Inductors

The 2727R-02H is a fixed inductor manufactured by Johanson Technology for various applications in the electronics industry. Generally speaking, fixed inductors are passive two-terminal electronic components with no particular shape—often an unbounded length of wire—which carry an electrical current. The inductor is designed to resist changes in electrical current applied to it, so it is also referred to as an inductor.Inductors serve multiple purposes in electronics, including signal filtering, blocking high frequency signal paths, coupling, balancing oscillator and radio frequency circuits, blocking DC current and smoothing pulsating DC supply. The 2727R-02H is used for these circuits in particular which require precise and reliable performance.

Application Field

The 2727R-02H is designed for 0.5-GHz frequency range applications up to 3.5 GHz. It is well-suited to wireless and RF applications such as antenna tracking, frequency sources, and power converters. The inductor has a wide operating temperature range, from -55°C to +150°C. The inductor also has high reliability and can hold up to 150mA in continuous operation.

Working Principle

An inductor works by the law of induction. Given an alternating current through an inductor, an electrical field is created, which resists any changes in the current. This opposes the movement of electrons, and the resistance affects the current and voltage in the circuit. The type of inductor used dictates the amount of resistance to current that is generated.When used in electronic circuits, inductors can dissipate power in the form of heat, which must be managed accordingly. The 2727R-02H is designed with a custom-designed shield and package that are optimized for thermal performance while maximizing shielding effectiveness, to minimize heat generation.The 2727R-02H has a single, flat-wire terminal design which makes the inductor easier to integrate into PCBs for space-constrained applications. The inductor is compatible with most solder reflow and wave processes.

Conclusion

The 2727R-02H is a versatile fixed inductor which is best suited for wireless and RF applications such as antenna tracking systems, frequency sources, and power converters. The inductor is designed with ease of integration in mind, as well as high reliability and an extended temperature range. It is a reliable and cost-effective solution for low-frequency applications up to 3.5 GHz.
