ECS-200-10-33B-CKM-TR3

Crystals Overview

The ECS-200-10-33B-CKM-TR3 is a surface-mount quartz crystal from the ECS-33B series, manufactured by ECS Inc. It operates at a nominal frequency of 20 MHz with a frequency stability and tolerance of ±10 ppm. The component features a load capacitance of 10 pF and an equivalent series resistance (ESR) ranging from 40 to 60 Ohms depending on specific documentation sources. It utilizes a 4-SMD, no-lead package with dimensions of 3.20mm x 2.50mm x 0.80mm maximum height. The device supports fundamental mode operation and functions within a temperature range of -20°C to +70°C.

Crystals Feature Summary

• Surface-mount design in a compact 3225 package for automated assembly
• Fundamental mode quartz resonance for stable timing signals
• RoHS3 compliant construction without REACH restrictions

Crystals Applications

• Microcontroller clock generation circuits
• Communication interface timing references
• General-purpose digital system oscillators

Crystals Procurement Notes

Verify the exact ESR specification against the manufacturer's current datasheet, as values vary between 40 and 60 Ohms across different documentation versions. Confirm that the CKM-TR3 suffix corresponds to the required tape and reel packaging format for your production line. Ensure compatibility with the target circuit's load capacitance requirements before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 20 MHz fundamental frequency with ±10 ppm stability is required for space-constrained designs. The 3225 package size offers a balance between thermal mass and board real estate. Consider the operating temperature range limits for environments exceeding 70°C or dropping below -20°C, where alternative industrial-grade crystals may be necessary.

Crystals Part Context

This part belongs to the ECS-33B series of low-profile quartz crystals designed for high-volume surface-mount applications. The series emphasizes consistent performance and reliability for consumer and industrial electronics. The specific model integrates standard electrical characteristics suitable for general timing purposes rather than specialized RF or precision measurement applications.

Crystals Replacement Considerations

Direct substitutes include other 20 MHz SMD crystals with identical 3225 footprint and 10pF load capacitance. Verify that replacement parts match the ±10 ppm stability requirement and operate within the same -20°C to +70°C temperature range to ensure circuit compatibility.
