1. Overview

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.

HC49/US

Common UsesCrystals

2. 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.
