Product details

The DSC1001BI2-044.0000T: AEC-Q100 qualification places this oscillator in the automotive-grade bin, suitable for infotainment, ADAS sensor clocks, and body-control modules where the thermal and vibration profile exceeds commercial-grade limits. Supply voltage spans 1.8V to 3.3V, so it can run directly off a 1.8V MCU rail or a 3.3V peripheral bus without an external regulator — one less component on the BOM.

Standby power and active draw

Housed in a 4-SMD, No Lead package measuring 5.00mm x 3.20mm with a seated height of 0.90mm — a standard 5×3.2 mm footprint that matches many quartz XO land patterns, easing a drop-in replacement on existing layouts.

Frequently asked questions

How can I order DSC1001BI2-044.0000T or request a quote?

Submit an RFQ with your target quantity and target price. The part is Active and sourced through independent distribution; we confirm availability and provide a firm quote per your BOM line.

Is DSC1001BI2-044.0000T AEC-Q100 qualified?

Yes, it carries AEC-Q100 rating, which means it has passed automotive-grade reliability stress tests — temperature cycling, ESD, latch-up — and is suitable for under-hood and cabin electronics.

What is the standby current of DSC1001BI2-044.0000T?

When the Standby (Power Down) function is active, the disable current is 15 µA max, allowing long sleep periods in battery-powered designs.
