Product details

The DSC1033AE1-005.0000 is a MEMS-based standard XO (oscillator) from Microchip's PureSilicon™ series, delivering a 5 MHz CMOS output from a 3.3 V supply rail. The 4-SMD, no-lead exposed pad package (7.00 mm x 5.00 mm footprint, 0.90 mm seated height) is a standard oscillator footprint that drops into most 5.0 mm x 7.0 mm clock sockets without a layout change.

A standby (power-down) pin lets the designer pull the oscillator into a low-power state: the disable current is 1 µA max, versus 3 mA typical during active oscillation. For a battery-powered sensor node that clocks only during measurement bursts, the standby current is below the self-discharge rate of a coin cell — the node can sleep for months without draining the battery on the oscillator alone.

Frequently asked questions

Does DSC1033AE1-005.0000 require external load capacitors?

No. Because the DSC1033AE1-005.0000 is a MEMS-based oscillator (not a bare crystal), the timing element is fully integrated inside the package. No external load capacitors are needed — the part is a drop-in clock source with a CMOS output that drives the downstream load directly.

What is the difference between DSC1033 and DSC1033AE1?

The base product number DSC1033 covers the entire PureSilicon™ MEMS XO family. The suffix 'AE1' in DSC1033AE1-005.0000 encodes the specific configuration: 3.3 V supply, ±50 ppm stability, -20°C to 70°C temperature range, and standby function. Other suffix variants may differ in supply voltage, stability grade, or temperature range — always match the full order code to the BOM requirement.

Where can I buy DSC1033AE1-005.0000 and how do I get a price?

The DSC1033AE1-005.0000 is available through independent distribution. Submit an RFQ with your target quantity (e.g., 100 or 1000 pieces) and the team will confirm availability and current pricing. No stock-holding claim is made here; the quote is generated per order.
