402F24012IJR Application Field and Working Principle

402F24012IJR is a low-frequency crystal unit manufactured by Abracon LLC. It is primarily used in the conversion of signals from DC power to AC output in low-frequency applications.

402F24012IJR crystal units are comprised of three parts: a quartz crystal, a piezo-electric transducer and an excitation circuit. The quartz crystal is the main component and the source of the desired frequency for the application. The piezo-electric transducer converts electrical energy into mechanical energy, and the excitation circuit receives electric energy from an AC or DC voltage source and converts it into a specific frequency output.

The quartz crystal of the 402F24012IJR crystal unit is tunable over a range of frequencies between 2.4 kHz and 4.8 kHz and has a temperature coefficient of -3 ppm/°C. The transduction coefficient is 25 μV/m/MHz, and the maximum capacitance is 50 pF max. The excitation circuit contains three separate high-frequency transistors arranged to form a bridge configuration that is used to match the impedance of the crystal.

The 402F24012IJR unit is primarily used in the low-frequency output of DC-power-fed devices. It is common for these devices to have a control board that controls the DC input, as well as the frequency and amplitude of the output signal. The 402F24012IJR crystal unit is used to generate the required frequency for these devices, typically in the range of 2.4 - 4.8 kHz, with the output level being adjustable by changing the input voltage.

Furthermore, the 402F24012IJR crystal unit can be used in applications such as frequency standards, radio transmissions, broadband radio modems and receivers, audio amplifiers, RF transmitters and receivers, and portable radios. It is also ideal for use in single-frequency, narrowband and broadband applications, as well as in high power and high temperature applications.

In conclusion, the 402F24012IJR crystal unit is a specialized low-frequency crystal used in a wide range of applications. These included conversions of signals from DC power to AC output, as well as applications in frequency standards, radio transmissions, audio amplifiers, and more. The crystal is manufactured by Abracon LLC and is tunable over a range of frequencies between 2.4 kHz and 4.8 kHz, with a temperature coefficient of -3 ppm/°C and a transduction coefficient of 25μV/m/MHz.
