SSP-T7-FL (SMD type low CL resonator for low-power microcontrollers)

The SSP-T7-FL is a surface-mounted resonator specially developed and released for ultra-low-power microcontrollers.
Through collaboration with major microcontroller manufacturers, we achieved low power consumption resonator.
Because the specifications for the microcontrollers indicated at the right differ from the general specifications, be sure to use SSP-T7-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 SSP-T7-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)
♦ Ultra-thin type with height of 1.4 mm
♦ SMD type suitable for high-density surface mounting
♦ Contains highly reliable cylinder-type quartz crystal created using photolithographic process
♦ Excellent shock and heat resistance
♦ RoHS directive compliant
APPLICATIONS
Ideal for use in battery operated devices where reduced standby energy consumption is critical.
