Product details

35.328 MHz MEMS XO – 3 mA draw, 1 µA standby

At 3 mA typical supply, it adds negligible heat to the board; the 1 µA standby current (disable pin active) lets a battery-powered system sleep for months without the oscillator draining the cell.

Listed as Active by Microchip.

Housed in a 4-SMD no-lead package measuring 0.126" × 0.098" (3.20 mm × 2.50 mm) with a seated height of 0.035" (0.90 mm). The land pattern matches the standard MEMS oscillator footprint — no via-in-pad required, and the four pads route easily on a two-layer board.

Frequently asked questions

How can I order the DSC1033CI1-035.3280T or check availability?

The DSC1033CI1-035.3280T is an active Microchip part, available through independent distribution. No stock-holding claim — sourced per order.

What is the standby current of the DSC1033CI1-035.3280T?

When the standby (power-down) function is active, the supply current drops to 1 µA maximum. This allows the oscillator to be gated off during system sleep without a separate load switch.

Is the DSC1033CI1-035.3280T obsolete or end-of-life?

No. The product status is Active with no end-of-life notice from Microchip. It can be used in new designs and is not subject to a last-time-buy window.
