49SMSS0870BMDAJDGEE-TR

Crystals Overview

The HKC 49SMSS0870BMDAJDGEE-TR is a surface acoustic wave (SAW) crystal oscillator designed for precision timing applications. It operates at a fundamental frequency of 8.704 MHz with a frequency tolerance of ±20 ppm. The component utilizes a 2-SMD, no lead package configuration suitable for automated surface mount assembly. Key electrical parameters include a load capacitance of 18 pF and an equivalent series resistance (ESR) of 50 Ohms. This device provides stable clock signals for digital circuits requiring accurate frequency reference.

Crystals Feature Summary

• Provides precise frequency generation using SAW technology
• Designed for surface mount integration via 2-SMD no lead package
• Ensures signal stability with specified load capacitance and ESR values

Crystals Applications

• Digital circuit clock sources
• Communication equipment timing references
• Consumer electronics internal synchronization

Crystals Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging if required for high-volume manufacturing processes. Confirm that the 8.704 MHz frequency aligns with system clock requirements. Ensure the 18 pF load capacitance matches the oscillator circuit design to maintain the stated ±20 ppm tolerance. Check compatibility with the 2-SMD no lead footprint on the target PCB layout.

Crystals Selection Notes

Select this component when a stable 8.704 MHz reference is needed in a compact surface mount form factor. The 50 Ohm ESR and 18 pF load capacitance define the matching network requirements. Consider the ±20 ppm tolerance for applications where moderate frequency accuracy is sufficient. The no lead construction supports standard SMT reflow processes.

Crystals Part Context

This part belongs to the family of SAW crystal oscillators manufactured by HKC. These components are distinct from LCD monitors also marketed under the HKC brand. The model number identifies a specific passive electronic component used for timing rather than display output. It serves as a frequency reference source within larger electronic assemblies.

Crystals Replacement Considerations

Direct substitutes must match the 8.704 MHz frequency, 18 pF load capacitance, 50 Ohm ESR, and 2-SMD no lead package dimensions. Verify that alternative suppliers offer the same ±20 ppm tolerance. Ensure the replacement part supports the same operating temperature range and mounting process.
