Product catalog summary

Overview: The document provides technical specifications for the HC-52/U quartz crystal units manufactured by KVG Quartz Crystal Technology. These units are AT-Cut and operate within a frequency range of 5 to 300 MHz.

Specifications:

Dimensions: The package dimensions vary with options for 8.8 mm, 8.0 mm, and 6.0 mm in height.
Temperature Stability: Operates between -55°C to +105°C, with nominal temperature stability of ±5°C.
Overtone Frequency: Available in various overtone frequencies ranging from 5 MHz to 300 MHz with different ppm tolerances.
Calibration Tolerance: ±10 ppm.

Standards and Compliance:

Complies with DIN 45110: N4, IEC 122-3: EB, NFC 93-601: n0 17, and MIL-H-10056: HC-52/U.

Electrical Characteristics:

Motional Resistance (R1): Varies with frequency, with maximum resistance ranging from 30Ω to 200Ω depending on the overtone.
Shunt Capacitance (C0): 2.2pF ± 0.8pF for 5-10 MHz and 3.0pF ± 1.0pF for 10-300 MHz.

Modifications and Options:

Options for additional modifications include a third wire for grounding, 3-point mounting for shock and vibration resistance, and SMD versions with metal clips.
