HC/49US (AT49) ULTRA LOW ESR
SMD LOW PROFILE CRYSTAL
ABLS-LR
Pb
RoHS
Compliant
11.5 x 4.8 x 4.2 mm
|||||||||||||||
FEATURES:
• 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
APPLICATIONS:
• Low negative resistance u-controller design
for low frequency
• Wide range of automotive applications
• Industrial applications
