This page contains info on the HC-49/U-S SMD component package that is commonly used to house older SMD crystal. For info on un-named SMD crystal packages (which are more common than the HC-49/U-S due to their smaller size), see the SMD Crystal Packages page.
|Synonyms||HC49/US, HC-49US, HC49-US|
|Variants||There a four variants for different height sizes (but same PCB land pattern).|
|Similar To||HC-49/S (though-hole version)|
|Solderability||Easy to solder, as the leads extrude beyond the edge of the package.|
|Thermal Resistance||n/a (this package is used for low power crystals, not normally relevant)|
|Land Area||57.8mm2 (12.3x4.7mm)|
Common footprint for larger SMD crystals. Internal circuitry is shielded by metal case. Comes in 4 height variants (A, B, C and D). The power consumption of crystals in these package usually ranges from 1nW to 1mW, with a typical value being 50uW.
