Overview

The ABS04W-32.768KHZ-6-D2-T5 is an ultra-miniature surface-mount crystal designed for low-power timing applications. It operates at the standard 32.768 kHz frequency with a 6pF load capacitance, making it suitable for real-time clock (RTC) circuits in space-constrained designs. The 1.2mm x 1.0mm footprint and low profile of 0.35mm facilitate high-density PCB layouts.

Why Choose This Part

This crystal features an exceptionally small 1.2 x 1.0 mm footprint and a maximum height of 0.35mm, significantly reducing PCB area compared to standard 3.2 x 1.5 mm crystals. Its 6pF load capacitance is optimized for modern ultra-low-power microcontrollers, and it maintains a frequency tolerance of +/-20ppm across an operating temperature range of -40 degC to +85 degC.

Applications

Real-Time Clock (RTC)
Provides the base reference frequency for MCU internal RTC peripherals to maintain accurate time-of-day.
Low-Power Sleep Modes
Used as a low-frequency clock source to maintain system timing while the main high-speed oscillator is disabled to save power.
Wearable Electronics
The ultra-thin 0.35mm height is ideal for smartwatches, fitness trackers, and other height-sensitive portable devices.
Wireless Sensor Nodes
Serves as a stable timing reference for periodic wake-up cycles in battery-operated IoT sensors.

Getting Started

When integrating this crystal, ensure that the PCB trace lengths to the MCU oscillator pins are minimized to reduce parasitic capacitance. Use the specified 6pF load capacitance and account for stray board capacitance when selecting external capacitors. Consult the microcontroller datasheet for the required transconductance (gm) to ensure reliable startup with the 130 kOhm maximum ESR.
