E1SEA18-24.576M TR

Crystals Overview

The E1SEA18-24.576M TR is a quartz crystal resonator manufactured by Ecliptek, designed for surface-mount applications. It operates at a nominal frequency of 24.576 MHz with a parallel fundamental mode. The component features an HC-49/US short package and utilizes resistance welding for sealing. Key electrical parameters include a load capacitance of 18 pF, an equivalent series resistance (ESR) of 40 Ohms maximum, and a shunt capacitance of 7 pF maximum. Frequency tolerance is specified at ±30 ppm at 25°C and ±50 ppm over the operating temperature range of -20°C to +70°C. Aging stability is rated at 5 ppm per year maximum.

Crystals Procurement Notes

Verify that the specific order suffix matches the required tape and reel packaging configuration. Confirm compliance with RoHS3 standards if restricted substances are prohibited in the target assembly. Ensure the selected variant aligns with the specified operating temperature range requirements for the final application environment.

Crystals Selection Notes

Select this component when a standard 24.576 MHz reference is required for surface-mount PCB layouts. The HC-49/US short form factor offers a compact footprint suitable for space-constrained designs. Consider the ±50 ppm total stability over temperature when designing systems requiring precise timing accuracy across varying thermal conditions.

Crystals Part Context

This part belongs to the E1SEA series of quartz crystals from Ecliptek. The series focuses on providing reliable, cost-effective resonators for mass-produced electronics. The model designation indicates the specific frequency, load capacitance, and package style within the manufacturer's standardized product line.

Crystals Replacement Considerations

Direct substitutes must match the 24.576 MHz frequency, 18 pF load capacitance, and HC-49/US SMD package dimensions. Verify that alternative components meet or exceed the 40 Ohm ESR limit and maintain similar aging characteristics to ensure circuit performance consistency.
