PSC Code 5955 covers Oscillators and Piezoelectric Crystals, which are key electronic components used in frequency control and signal generation applications. This category includes crystal units, processed unmounted crystals, as well as crystal controlled and noncrystal controlled oscillators. These components are crucial for ensuring timing precision and stability in a wide array of electronic systems utilized by federal agencies. Government procurement under PSC 5955 typically involves acquiring these components for use in communications, navigation, radar systems, and other mission-critical electronics. This PSC excludes electronic modules as defined under FSC 5963 and microcircuits, ensuring a clear distinction between component-level purchases and integrated electronic assemblies.
