• Ultra low ESR as low as 20 ohms for 4MHz, 85% lower than

typical SMD Low Profile HC49S Crystals

• Low negative resistance(-R) IC design can ensure high oscillation margin

• Tight stability and automotive grade temperature available

• Hermetically resistance weld sealed

RoHS

Compliant

11.5 x 4.8 x 4.2 mm
