H-35U 100MHz Crystal

100.000MHz SC-Cut Quartz Crystal – H-35U Vacuum Sealed

Product Overview:

The XTALONG H-35U 100MHz crystal is a premium-grade SC-Cut (Stress Compensated) Quartz Crystal Resonator engineered for ultra-high-stability timing applications. Operating in the 5th Overtone mode, this crystal delivers an exceptionally high Q-Factor (≥110k) and outstanding phase noise performance.

Housed in a robust, vacuum-sealed H-35U cold-weld package, it provides excellent resistance to thermal transients, aging, and mechanical vibration. It is specifically designed to act as the precision core for high-end Oven-Controlled Crystal Oscillators (OCXOs) used in aerospace, radar, and advanced telecommunication systems.

Key Features:

• SC-Cut Technology: Stress-compensated cut for superior thermal stability and rapid warm-up characteristics.

• 5th Overtone Mode: Ensures ultra-low phase noise and high Q-Factor for pristine signal quality.

• Optimized LTTP: Lower Temperature Turn Point designed at (85±7)°C, ideal for standard OCXO oven integration.

• Hermetically Sealed: Vacuum-sealed H-35U package ensures ultra-low aging (≤±0.3ppm/year).

• Harsh Environment Ready: Wide operating temperature range from -55°C to +105°C.

Target Applications:

• Core resonator for Ultra-Low Phase Noise OCXOs.

• Reference clocks for Radar and Aerospace systems.

• Precision Frequency Synthesizers and RF equipment.

• Advanced Test & Measurement instrumentation.
