E1SGA18-25.000M TR

Crystals Overview

The E1SGA18-25.000M TR is a surface-mount quartz crystal resonator from the E1S series, manufactured by Ecliptek. It operates at a nominal frequency of 25.000 MHz with a load capacitance of 18 pF. The component features an HC-49/UP short package with two pads and a maximum height of 3.2 mm. Electrical specifications include a frequency tolerance of ±15 ppm at 25°C and stability of ±30 ppm over the operating range of 0°C to +70°C. The equivalent series resistance (ESR) is a maximum of 120 Ohms, with a drive level of 1 mWatt maximum. Aging is specified at 5 ppm per year maximum.

Crystals Feature Summary

• Surface-mount construction utilizing HC-49/UP short metal resistance weld seal packaging for reliable SMD integration.
• AT-cut fundamental mode operation ensuring stable parallel resonance characteristics for timing applications.
• Compliance with RoHS directives indicating lead-free manufacturing processes.

Crystals Applications

• General-purpose clock signal generation in digital circuits
• Microcontroller and microprocessor system timing references
• Communication interface modules requiring precise frequency standards

Crystals Procurement Notes

Verify that the ordering suffix matches the required tape and reel configuration for automated assembly. Confirm that the specific variant aligns with the intended load capacitance and frequency tolerance requirements for the target circuit design. Ensure compliance with environmental regulations applicable to the final product deployment region.

Crystals Selection Notes

Select this component when a standard 25 MHz reference is needed in a compact surface-mount form factor. Consider the 18 pF load capacitance requirement for circuit matching. Evaluate the 0°C to +70°C temperature range against operational environmental conditions. Compare ESR limits with oscillator driver capabilities to ensure adequate startup performance.

Crystals Part Context

This part belongs to the E1S series of quartz crystals produced by Ecliptek. The series offers various frequency options within the HC-49/UP short package format. These components are designed as passive frequency control elements for electronic systems requiring stable oscillation frequencies without integrated active circuitry.

Crystals Replacement Considerations

Direct substitutes may include other HC-49/UP SMD crystals with identical 25 MHz frequency, 18 pF load capacitance, and compatible ESR values. Verify package dimensions and pin compatibility before substitution. Cross-reference with Abracon EA2532QA18-25.000M TR only if size reduction is acceptable, noting the package difference.
