E1SJA18-10.000M TR

Crystals Overview

The E1SJA18-10.000M TR is a surface-mount quartz crystal resonator from the E1S series, manufactured by Ecliptek / Abracon. It operates at a nominal frequency of 10.000 MHz with a parallel resonant mode. The component features an AT-cut fundamental design and supports a load capacitance of 18 pF. Electrical specifications include a frequency tolerance of ±15 ppm at 25°C, aging stability of ±5 ppm/year maximum, and a maximum equivalent series resistance of 70 Ohms. It is housed in a standard HC-49/US package with SMD/SMT mounting style.

Crystals Feature Summary

• AT-cut fundamental quartz construction for stable oscillation
• Resistance welded metal seal for environmental protection
• Surface mount (SMD) form factor compatible with automated assembly

Crystals Applications

• General-purpose clock signal generation in electronic circuits
• Microcontroller and microprocessor system timing references
• Communication equipment frequency standards

Crystals Procurement Notes

Verify current availability status as this part may be subject to discontinuation or limited supply. Confirm that the specific trailing suffix corresponds to the required tape and reel packaging configuration. Ensure compatibility with existing PCB footprint designs before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 10 MHz reference with ±15 ppm initial tolerance is required. The 18 pF load capacitance must match the oscillator circuit design. Consider the HC-49/US package dimensions for board space constraints. Verify drive level requirements do not exceed the specified maximums for long-term reliability.

Crystals Part Context

This part belongs to the E1S series of surface-mount crystals. It shares the physical HC-49/US package profile with other variants in the lineup but differs in electrical parameters such as frequency and tolerance. It serves as a direct replacement for through-hole HC-49/U crystals where surface mount technology is preferred.

Crystals Replacement Considerations

Direct substitutes within the same series include E1SJA18-12.000M TR and E1SCA18-10.000M TR, provided frequency and tolerance differences are acceptable. Cross-reference with E2SCA18-15.000M if higher frequencies are needed, noting package variations.
