EA3250JA18-12.000M TR

Crystals Overview

The EA3250JA18-12.000M TR is a 12.000 MHz fundamental mode AT-cut quartz crystal resonator manufactured by Ecliptek. It features a 4-pin surface mount package with no leads, designed for automated assembly. The component operates within a frequency tolerance of ±15 ppm at 25°C and stability of ±20 ppm over the -40°C to +85°C temperature range. It utilizes an 18 pF load capacitance and has a maximum equivalent series resistance (ESR) of 60 Ohms. The drive level is limited to 1 mWatt maximum, ensuring reliable operation in standard oscillator circuits.

Crystals Feature Summary

• Fundamental mode AT-cut quartz construction for stable frequency generation
• 4-pin surface mount package with no leads for compact PCB integration
• Parallel resonant operation optimized for standard microcontroller clock applications

Crystals Applications

• Microcontroller system clock sources
• Communication interface timing circuits
• General-purpose digital logic timing references

Crystals Procurement Notes

Verify the specific ordering suffix and manufacturer designation, as Ecliptek products are often distributed under Abracon branding. Confirm RoHS compliance status and check for End-of-Life notifications, as availability may be restricted. Ensure the 4-pin SMD footprint matches the target PCB design before finalizing procurement orders.

Crystals Selection Notes

Select this component when a low-profile, leadless surface mount crystal is required for 12 MHz applications. The 18 pF load capacitance aligns with common MCU oscillator configurations. Verify that the circuit drive level does not exceed 1 mWatt to prevent frequency instability or crystal damage during selection.

Crystals Part Context

This part belongs to the EA3250 series of surface mount crystals from Ecliptek. It is functionally similar to other 12 MHz variants in the lineup but distinguished by its specific 4-pin leadless package and 18 pF load capacitance specification. It serves as a direct replacement for legacy through-hole HC-49 crystals where space constraints necessitate a smaller form factor.

Crystals Replacement Considerations

Direct substitutes include the EA3250QA18-12.000M TR, which shares identical electrical parameters but may differ in packaging details. Cross-reference with EB3250JA12-12.000M TR if a 12 pF load capacitance variant is acceptable. Always verify pinout compatibility and mounting height restrictions when substituting.
