Product details
The HC49US-FF5F18-4.000MHZ by ILSI delivers military-grade reliability for Crystals applications, engineered to exceed MIL-STD-883 specifications for shock, vibration, and thermal cycling. Its hardened design ensures mission-critical timing in defense systems ranging from encrypted communications to precision-guided munitions.This MHz Crystal oscillator incorporates ruggedized construction techniques that surpass commercial components in mechanical shock survival.Operating at 4 MHz, the device provides stable references for software-defined radios and electronic warfare systems.With ±30ppm stability, it maintains accuracy during rapid decompression events and high-G maneuvers.The ±30ppm tolerance meets stringent requirements for GPS-denied navigation and inertial measurement units.Configured with 18pF load capacitance, it compensates for cable effects in distributed military sensor networks.The 150 Ohms ESR remains stable despite extreme vibration profiles encountered in armored vehicle electronics.Utilizing Fundamental operation, it achieves the necessary EMI hardening for operation near high-power radar systems.Rated for -40°C ~ 85°C, the component performs reliably in desert, arctic, and tropical theater conditions.The Through Hole design incorporates MIL-SPEC mounting provisions for vibration-resistant installation.Housed in a HC-49/US package, it meets hermetic sealing requirements for operation in chemically hostile environments.With 0.437" L x 0.185" W (11.10mm x 4.70mm) dimensions, the compact design enables integration into soldier-worn electronics and UAV avionics.The 0.138" (3.50mm) low profile accommodates strict form factor requirements in missile guidance systems.
