Product details

The supply voltage spans 2.25 V to 3.6 V, covering the common 2.5 V and 3.3 V logic rails without an external regulator. This is useful for power-cycled domains in automotive ECUs that must meet quiescent-current budgets during sleep modes.

Housed in a 6-SMD no-lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm. The no-lead construction means the terminations are flush with the package body — no bent leads to inspect, but the solder-paste stencil aperture must match the pad geometry exactly to avoid head-in-pillow defects. The 0.50 mm pitch is standard for this form factor; the PCB land pattern follows the JEDEC MO-252 recommendation.

Frequently asked questions

Is the DSC1121BI5-100.0000T a direct replacement for a quartz oscillator?

Yes, in most applications. The MEMS resonator is pin-compatible with standard 6-pin quartz oscillators in the same 5.0 x 3.2 mm package. The key difference is that the MEMS part does not require a load-capacitance match — the resonator is sealed at the factory, so there is no start-up margin to tune. Drop it onto the same PCB footprint and it runs at 100 MHz CMOS with ±10 ppm stability.

Does the DSC1121BI5-100.0000T meet AEC-Q100 automotive qualification?

Yes, it is rated AEC-Q100. This covers the full automotive reliability test suite: temperature cycling, ESD, latch-up, and extended life test.
