PBRC18.43HR50X000

PBRC18.43HR50X000 is a type of resonator, which is a passive and linear frequency-dependent network of inductors and capacitors. It is mainly used to filter and select signals by passing desired frequencies, eliminating undesired frequencies, and amplifying the passed signals. As such, this type of resonator can have a wide range of applications, from audio amplifiers and communications to medical imaging systems.

A typical PBRC18.43HR50X000 operates on a fundamental frequency from 50 kHz to 200 kHz. Its electrical equivalent circuit topology consists of two series-connected air-core inductors L1 and L2 and two series-connected capacitors C1 and C2, configured in a bridge pattern. At resonance, the inductors L1 and L2 resonate with a basic frequency determined mainly by the value of the two inductors, and the capacitors C1 and C2 resonate with a frequency determined mainly by the value of the capacitor values.

The PBRC18.43HR50X000 resonator also includes an internal parallel resonance circuit, connected between the series-connected capacitor C1 and the bridge point of the parallel circuit. This internal resonance circuit is used to fine tune the frequency of the resonator over a relatively wide range. This fine tuning is typically accomplished by changing the frequency of an external parallel reactive element, such as a varactor diode.

The working principle of the PBRC18.43HR50X000 resonator is to shift the frequency selection point from the basic frequency determined by the values of the inductors and capacitors to the resonance point determined by the internal parallel resonance circuit, with the external parallel reactance element providing additional adjustment for fine tuning over a wide frequency range.

The PBRC18.43HR50X000 resonator has a wide range suitable applications, including:

• In radio engineering, it can be used for signal filtering, selecting desired frequencies and amplifying them.
• In communications it can be used to help modulate signals.
• In medical imaging systems it is used to select the frequencies needed for imaging.

PBRC18.43HR50X000 resonators are a cost-effective, high-performance solution for a range of applications. They are used in a variety of products, such as audio amplifiers, switch-mode power supplies, computers, communication systems and medical equipment.

In conclusion, PBRC18.43HR50X000 resonators are indispensable components used in a wide range of electronic applications. Their design combines the use of two series-connected air core inductors and capacitors in a bridge pattern, and an internal parallel resonance circuit to provide fine tuning of the frequency selection point. This provides a highly selective filtering, selecting desired signals and amplifying them, while eliminating undesired signals.
