Product details
The QMQF574T25-2.5B-77.800 by Mercury United Electronics, Inc. redefines Oscillators technology, specifically engineered for extreme-radiation environments in nuclear power monitoring systems. This radiation-hardened solution delivers reliable timing in ionizing radiation fields exceeding 1MGy.Featuring Crystal technology with sapphire insulation, the device maintains <1ppm frequency deviation after 10 years of continuous gamma exposure in reactor vessel instrumentation.As a TCXO, this oscillator implements triple-modular redundancy with <1ms failover time, critical for safety-critical nuclear control systems.Operating at 77.8 MHz with radiation-induced phase error correction, the solution meets IEC 61508 SIL 3 requirements for reactor protection systems.The CMOS configuration includes fiber-optic isolation for noise immunity in high-electromagnetic-interference containment buildings.With 2.5V operating range, the device maintains operation during station blackout scenarios with backup power fluctuations.Achieving ±2.5ppm stability with neutron flux compensation, the oscillator enables precise timing in neutron flux monitoring chambers.Rated for -30°C ~ 85°C operation, the device withstands LOCA (Loss-of-Coolant Accident) steam conditions.The 24mA (Typ) radiation-hardened design ensures stable operation in spent fuel pool monitoring systems.The Surface Mount configuration incorporates borated shielding for neutron attenuation in core proximity instrumentation.The 4-SMD, No Lead package features zirconium alloy encapsulation for corrosion resistance in primary coolant loops.With 0.276" L x 0.197" W (7.00mm x 5.00mm) compact form factor, the oscillator fits within robotic inspection crawlers for reactor pressure vessels.The 0.102" (2.60mm) low-profile design enables installation in fuel rod gap monitors.
