830054236

Crystals Overview

The Würth Elektronik part number 830054236 is a surface-mount crystal oscillator component belonging to the WE-XTAL series. It operates at a fundamental frequency of 32.768 kHz with a load capacitance specification of 6 pF and a frequency tolerance of ±20 ppm. The device utilizes a CFPX-217 package format, featuring dimensions of 3.2 mm in length, 2.5 mm in width, and 0.9 mm in height. It incorporates an equivalent series resistance (ESR) value of 70 kOhms and is designed for through-hole or surface-mount integration depending on specific board layout requirements.

Crystals Feature Summary

• Provides precise timing stability suitable for real-time clock applications
• Utilizes a compact surface-mount footprint for space-constrained designs
• Engineered for resilience against environmental variations

Crystals Applications

• Real-time clock circuits in consumer electronics
• Microcontroller system oscillators
• Low-power embedded devices requiring accurate timekeeping

Crystals Procurement Notes

Verify the exact package variant and lead-free status against the latest manufacturer datasheet before ordering. Confirm that the load capacitance matches your circuit design requirements. Ensure compatibility with standard reflow soldering profiles if using surface-mount assembly methods. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Crystals Selection Notes

Select this component when a stable 32.768 kHz reference is required for low-frequency timing applications. Consider the ±20 ppm tolerance as sufficient for general-purpose clocks but potentially insufficient for high-precision metrology. Evaluate the 70 kOhm ESR against your oscillator circuit's drive level limitations to prevent over-driving the crystal. Compare physical dimensions against available PCB real estate.

Crystals Part Context

This component is part of Würth Elektronik’s WE-XTAL line, which focuses on passive timing elements. The CFPX-217 designation refers to the specific case size and pin configuration. It serves as a critical timing source for digital systems, replacing older through-hole variants where space efficiency is prioritized without sacrificing frequency accuracy.

Crystals Replacement Considerations

Direct substitutes must match the 32.768 kHz frequency, 6 pF load capacitance, and similar physical dimensions. Verify equivalent ESR values to ensure circuit stability. Check for compatible mounting styles and thermal characteristics. Consult manufacturer cross-reference lists for verified alternatives.
