The component features an equivalent series resistance (ESR) of 80 kOhms and supports a drive level of 0.1 uW. It is housed in a 2-pin ultra-miniature SMD package measuring 2 mm x 1.2 mm x 0.6 mm. The device functions within a temperature range of -40°C to +85°C and complies with RoHS standards.

Crystals Feature Summary

• Ultra-miniature surface-mount design for space-constrained applications
• High stability tuning fork crystal structure
• Compliant with environmental restriction standards

Crystals Applications

• Real-time clock circuits in portable electronics
• Timekeeping modules in consumer devices
• Low-power embedded systems requiring precise timing

Crystals Procurement Notes

Verify the specific suffix TR9 indicates tape-and-reel packaging configuration when sourcing. Confirm that the 4 pF load capacitance matches the target circuit design requirements. Ensure the 80 kOhm ESR value is compatible with the oscillator driver circuit constraints. Check for RoHS compliance documentation availability during the procurement phase.

Crystals Selection Notes

Select this component when a compact footprint is critical for the PCB layout. The 4 pF load capacitance requires careful matching with the host circuit's stray capacitance to maintain accuracy. Consider the 80 kOhm ESR limit when designing the oscillator feedback loop. This part is suitable for applications operating between -40°C and +85°C.

Crystals Part Context

This model belongs to the ECX-12 series of ultra-miniature crystals from ECS. It represents a compact alternative to larger standard-sized tuning fork crystals. The series is designed for modern electronics where board space is limited. It shares the 32.768 kHz frequency standard used globally for timekeeping.
