GL045F35IET

Crystals Overview

The GL045F35IET is a surface-mount crystal oscillator manufactured by CTS-Frequency Controls. It operates at a fundamental frequency of 4.5 MHz with a load capacitance of 20 pF and an equivalent series resistance (ESR) of 40 Ohms. The component features a frequency stability and tolerance of ±20 ppm. It is housed in a 2-SMD, no-lead package measuring 5.00mm x 3.20mm with a maximum seated height of 1.35mm. The device supports an operating temperature range of -10°C to +60°C and utilizes glass seal technology for environmental protection.

Crystals Feature Summary

• Utilizes glass seal construction for enhanced environmental durability
• Designed for surface mount assembly on printed circuit boards
• Operates in fundamental mode for precise frequency generation

Crystals Applications

• General purpose timing circuits requiring stable reference frequencies
• Microcontroller clock sources in consumer electronics
• Communication modules needing 4.5 MHz signal generation

Crystals Procurement Notes

Verify the specific suffix IET against official CTS documentation to confirm exact electrical tolerances and packaging specifications. Ensure compatibility with the target load capacitance of 20pF in the circuit design. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement to align with manufacturing standards.

Crystals Selection Notes

Select this component when a 4.5 MHz fundamental frequency is required with moderate stability. The 20pF load capacitance must match the oscillator circuit design. Consider the 40 Ohm ESR for power consumption constraints. The limited operating temperature range suits indoor or controlled environment applications rather than extreme industrial conditions.

Crystals Part Context

This part belongs to the CTS Frequency Controls portfolio of passive frequency control components. It serves as a standalone resonator element rather than an active oscillator IC. The product line emphasizes reliability through glass seal technology, distinguishing it from standard epoxy-sealed crystals in terms of long-term stability and environmental resistance.

Crystals Replacement Considerations

Consult official substitution guides for direct equivalents. Generic replacements may differ in ESR, load capacitance, or physical dimensions. Verify that any substitute maintains the 4.5 MHz frequency and 20pF load requirement to ensure circuit functionality without redesign.
