FA-238 50.0000MA30X-C3

Crystals Overview

The EPSON FA-238 50.0000MA30X-C3 is a surface-mount MHz crystal operating at 50.0000 MHz with ±20 ppm frequency tolerance and ±30 ppm stability. It features an 18 pF load capacitance, 40 Ohms equivalent series resistance (ESR), and a 4-SMD, no lead package measuring 3.20mm x 2.50mm x 0.70mm maximum height. Designed for base mode operation, it supports a working temperature range of -40°C to +85°C and complies with RoHS 3 standards.

Crystals Feature Summary

• Compact 3.2mm x 2.5mm surface-mount footprint for space-constrained designs
• High frequency stability with ±20 ppm tolerance for precise timing applications
• Low equivalent series resistance of 40 Ohms for efficient circuit integration

Crystals Applications

• Clock generation for microprocessors and microcontrollers
• Timing reference for communication interfaces
• Frequency control in consumer electronic devices

Crystals Procurement Notes

Verify the exact suffix against official Epson documentation to confirm specific tolerance and packaging variations. Ensure compatibility with reflow soldering profiles specified in the datasheet. Confirm RoHS 3 compliance status for regulatory requirements. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Validate load capacitance requirements with the target circuit design before procurement.

Crystals Selection Notes

Select this component when a 50 MHz frequency with tight ±20 ppm tolerance is required in a small SMD package. Consider the 18 pF load capacitance and 40 Ohm ESR for oscillator circuit matching. Evaluate the -40°C to +85°C operating range against environmental conditions. Compare with other FA-238 variants if different tolerances or frequencies are needed.

Crystals Part Context

This part belongs to the Epson FA-238 series of miniature crystals, designed for high-frequency applications requiring small form factors. The series offers various frequency options and tolerance levels within the same 3.2mm x 2.5mm package. It is engineered for reliability in consumer electronics and industrial equipment where space and precision are critical constraints.

Crystals Replacement Considerations

Direct substitutes include other FA-238 series parts with identical 50 MHz frequency and ±20 ppm tolerance but different suffixes indicating minor parameter variations. Verify pinout and electrical characteristics match exactly. Consult Epson's replacement guide for cross-referenced equivalents from other manufacturers if availability is an issue.
