Product details

4 MHz MEMS oscillator with standby power-down

A standby (power-down) function drops supply current to 1 µA max when disabled, making it suitable for battery-powered equipment that needs a wake-up clock source. The 4-SMD no-lead package measures 5.00 mm x 3.20 mm with a seated height of 0.90 mm, fitting standard oscillator footprints for industrial control, telecom, and sensor modules.

Microchip lists this part as Obsolete. Available through independent surplus channels in lot-specific quantities. Quoted to order against the BOM — confirm availability and pricing at RFQ.

Package and temperature grade for industrial use

The 4-SMD no-lead package requires standard reflow soldering; no exposed pad, so thermal management relies on board copper pour under the device.

Frequently asked questions

How can I order the DSC1033BI1-004.0000T or check availability?

This part is obsolete. We source it through independent distribution on a quoted-to-order basis. Submit an RFQ with your target quantity and target price; we confirm availability and current pricing at quote time.

What is the standby power-down function?

The standby (power-down) function disables the oscillator output and reduces supply current to 1 µA max, allowing the system to conserve power when the clock is not needed.
