VT-200-FL (Cylinder-type Low-CL Resonator for Low-Power Microcontrollers)

VT-200-FL is a cylinder-type resonator specially developed and released for ultra-low-power microcontrollers.
Through collaboration with major microcontroller manufacturers, we achieved low power consumption.
Because the specifications for the microcontrollers indicated at the right differ from the general specifications, be sure to use VT-200-FL if using such a microcontroller. Also check the circuit matching report, because the method for optimizing the load capacitance , the resistors and capacitors in the oscillation circuit differs for each microcontroller.

CAUTION
The VT-200-FL is designed for use in ultra-low-power microcontrollers. Do not use this resonator in regular microcontrollers as it might cause problems with oscillation.

FEATURES
♦ Consumes one tenth the standby power of general crystal resonators (with a load capacitance of 12.5 pF)
♦ Compact cylindrical shape
♦ Fabricated using photolithography
♦ Excellent shock and environmental resistance
♦ RoHS directive compliant.
♦ Complete Pb-free.
APPLICATIONS
Ideal for use in battery operated devices where reduced standby energy consumption is critical.
