HC/49US (AT49) ULTRA LOW ESR

SMD LOW PROFILE CRYSTAL

ABLS-LR

RoHS

11.5 x 4.8 x 4.2 mm

Compliant

FEATURES:

APPLICATIONS:

• Low negative resistance u-controller design

for low frequency

• Wide range of automotive applications

• Industrial applications

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

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

• Tight stability and automotive grade temperature available

• Hermetically resistance weld sealed
