S33305T-1.8432-X-R

Oscillators Overview

The S33305T-1.8432-X-R is a surface-mount crystal oscillator (XO) manufactured by Aker Technology Corp. It operates at a nominal frequency of 0.032768 MHz with a frequency stability of ±50 ppm. The device utilizes HCMOS output levels and supports a supply voltage range from 1.8V to 3.3V. It features a 4-pin CSMD package with no lead, measuring 3.2mm in length, 2.5mm in width, and 1.1mm in height. The component is designed for operation within a temperature range of -40°C to +85°C and complies with RoHS standards.

Oscillators Feature Summary

• Provides precise timing signals via HCMOS output interface
• Supports low-voltage operation down to 1.8V
• Compact surface-mount design suitable for space-constrained applications

Oscillators Applications

• Real-time clock circuits
• Microcontroller system clocks
• Low-frequency timing references

Oscillators Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm that the 0.032768 MHz frequency matches the target application requirements, as this is a specialized low-frequency value distinct from standard high-speed oscillators. Ensure the 4-pin footprint aligns with the PCB layout specifications.

Oscillators Selection Notes

Select this component when a stable 32.768 kHz signal is required in a surface-mount form factor. Consider the ±50 ppm stability for general timing applications rather than high-precision metrology. Verify compatibility with the system's voltage domain, as the device supports both 1.8V and 3.3V logic levels.

Oscillators Part Context

This part belongs to the S33305 series of standard crystal oscillators from Aker Technology. It shares the same physical footprint and pinout configuration as other variants in the series, such as the 32MHz and 50MHz models, allowing for potential mechanical interchangeability if electrical parameters are adjusted accordingly.

Oscillators Replacement Considerations

Direct substitutes include other S33305 series variants with different frequencies but identical packages, such as S33305T-32.000-X-R or S33305T-50.000-X-R, provided the frequency difference is acceptable for the circuit design.
