XTL901150-R53-029

Crystals Overview

The Siward XTL901150-R53-029 is a 40 MHz fundamental mode crystal resonator designed for surface-mount applications. It features a frequency tolerance of ±5ppm and an equivalent series resistance of 40 Ohms. The component operates with a load capacitance of 9pF and utilizes a compact 4-SMD, No Lead package measuring 1.6 x 1.2mm. This configuration supports precise timing requirements in space-constrained electronic designs.

Crystals Feature Summary

• Fundamental mode operation at 40 MHz
• Compact 1.6 x 1.2mm SMD footprint
• High frequency stability within ±5ppm

Crystals Applications

• Microcontroller clock sources
• Communication module timing
• Portable consumer electronics

Crystals Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required load capacitance and tolerance levels. Confirm that the 4-SMD no-lead package aligns with PCB layout constraints. Cross-reference the manufacturer datasheet for reflow soldering profiles and storage conditions to maintain component integrity during assembly.

Crystals Selection Notes

Select this component when a small form factor is critical alongside strict frequency accuracy. The 40 Ohm ESR suits standard oscillator circuits without requiring additional impedance matching. Ensure the operating temperature range meets the environmental demands of the target application before finalizing the design.

Crystals Part Context

This part belongs to the Siward XTL90 series of miniature crystals. It shares the same 1.6 x 1.2mm package dimensions as other variants in the lineup but differs in electrical parameters such as frequency and tolerance. The series targets high-density circuit board designs requiring reliable timing references.

Crystals Replacement Considerations

Direct substitutes must match the 40 MHz frequency, 9pF load capacitance, and 4-SMD no-lead package. Verify equivalent ESR and stability specifications from alternative manufacturers to ensure circuit performance remains unchanged.
