CS52-32.768K-12.5

Crystals Overview

The CS52-32.768K-12.5 is a 32.768 kHz crystal manufactured by Transko Electronics, Inc., designed for precision timing applications. It features a frequency tolerance of ±20ppm at normal temperature and operates within a temperature range of -40°C to +85°C. The component utilizes a 12.5pF load capacitance and exhibits a maximum equivalent series resistance (ESR) of 70 kOhms. It is housed in a compact 2-SMD, No Lead package with a maximum seated height of 0.039 inches (1.00mm). This device is suitable for low-power digital circuits requiring stable clock signals.

Crystals Feature Summary

• Provides precise 32.768 kHz frequency output for accurate timekeeping
• Operates reliably across extended industrial temperature ranges
• Utilizes low power consumption design suitable for battery-powered devices

Crystals Applications

• Real-time clocks in portable electronic devices
• Microcontroller system clock sources
• Low-power embedded monitoring systems

Crystals Procurement Notes

Verify the specific suffix '12.5' corresponds to the required 12.5pF load capacitance for your circuit design. Confirm that the 2-SMD no-lead package dimensions align with your PCB footprint requirements. Ensure the ±20ppm tolerance meets the timing accuracy specifications of your target application before finalizing procurement orders.

Crystals Selection Notes

Select this component when a standard 32.768 kHz reference is needed for real-time counting or synchronization. Consider the ±20ppm tolerance if long-term drift compensation is not implemented in software. Evaluate the 70 kOhm ESR limit against the oscillator circuit's drive level constraints to prevent overdriving the crystal element during operation.

Crystals Part Context

This part belongs to Transko's general-purpose crystal lineup, distinct from their MEMS oscillators and OCXO series. Unlike active oscillators, this passive component requires an external oscillator circuit to generate a square wave signal. It serves as a fundamental timing element rather than a complete clock solution.

Crystals Replacement Considerations

Transko offers the CS31-32.768K-12.5 as a similar alternative within their product family. Verify pin compatibility and electrical parameters before substitution. No other manufacturer drop-in replacements are officially documented for this specific part number.
