FAQ
Q1: What are the common frequency points available?
A: Standard frequencies include 5.5296MHz, 6MHz, 6.78MHz, 8MHz, etc. Custom frequencies are also supported upon request.
Q2: Why is the HC-49S X49SS3 Series Called "Fake-SMD"?
A: The term "Pseudo-SMD" (or "Fake SMD") refers to the HC-49S X49SS3 series' unique hybrid design, which combines traits of both through-hole and surface-mount components. The traditional HC-49S is a through-hole crystal with bent pins for PCB insertion. While X49SS3 "SMD" adaptation adds 3 flat solderable pads to the base, allowing surface mounting, but retains the HC-49S's bulky metal can.
Q3: Why does the HC-49S X49SS3 Series use"Fake-SMD" design?
A: Legacy Design Upgrades: Lets designers replace through-hole HC-49S without full PCB redesign.
Cost vs. Performance: Cheaper than miniaturized SMDs (e.g., 2520), but less space-efficient.
