E1SJA18-16.000M TR

Crystals Overview

The E1SJA18-16.000M TR is a quartz crystal resonator manufactured by Ecliptek, part of the E1S series. It features an HC-49/UP Short surface-mount package with two pads and a metal resistance weld seal. The nominal frequency is 16.000 MHz with a parallel resonant mode of operation. Frequency tolerance is ±15 ppm at 25°C and ±30 ppm over the -40°C to +85°C operating range. The load capacitance is 18 pF, shunt capacitance is 5 pF maximum, and equivalent series resistance is 80 ohms maximum. Aging is limited to 5 ppm per year.

Crystals Feature Summary

• Surface-mount construction utilizing an HC-49/UP Short package with a metal resistance weld seal for environmental protection.

Crystals Applications

• Clock signal generation in electronic circuits

Crystals Procurement Notes

Verify that the component matches the specific E1SJA18-16.000M TR designation from Ecliptek or Abracon. Confirm compliance with RoHS standards and lead-free status as documented in official datasheets. Ensure the ordering suffix corresponds to the required tape and reel packaging configuration for automated assembly processes.

Crystals Selection Notes

Select this component when a 16 MHz reference with ±15 ppm stability at room temperature is required. The HC-49/UP Short SMD form factor suits space-constrained designs needing robust sealing. Verify that the 18 pF load capacitance aligns with the oscillator circuit requirements and that the 80 ohm ESR fits the drive level constraints.

Crystals Part Context

This part belongs to the E1S series of quartz crystal resonators produced by Ecliptek, now associated with Abracon. The series includes various frequencies and packages, with the E1SJA variant specifically denoting the HC-49/UP Short surface-mount style. These components are designed for general-purpose timing applications requiring stable frequency output.

Crystals Replacement Considerations

Cross-reference with other manufacturers offering HC-49/UP SMD crystals with identical 16 MHz frequency, 18 pF load capacitance, and similar electrical tolerances to ensure functional compatibility.
