Product details

The DSC1033BE1-040.0000T is a 40 MHz MEMS-based XO (Standard) from Microchip's PureSilicon™ series, delivering a CMOS output at 3.3V with ±50ppm frequency stability.

No successor or cross-reference is recorded — the part is the current build target.

Housed in a 4-SMD, no-lead package measuring 0.197" x 0.126" (5.00 mm x 3.20 mm) with a seated height of 0.035" (0.90 mm), the DSC1033BE1-040.0000T fits standard oscillator land patterns. The surface-mount profile suits reflow assembly without requiring via-in-pad or special fan-out.

Frequently asked questions

Does the DSC1033BE1-040.0000T have a standby or power-down function?

Yes, the part includes a Standby (Power Down) function. When disabled, the maximum supply current drops to 1µA, allowing the oscillator to be gated off without removing the supply rail.
