Overview

Name	HC-49/U-S
Synonyms	HC49/US, HC-49US, HC49-US
Variants	There a four variants for different height sizes (but same PCB pand pattern).
Similar To	HC-49/S (though-hole version)
Mounting	SMD
Pin Count	2
Pitch	9.5mm
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)
Height	A B C D
3D Models	HC49/US
Common Uses	Crystals

Comments

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.
