Raltron Introduces RT1008 Ultra-Small 32.768 kHz Tuning Fork Crystal for Space-Constrained Wearable Designs

RT1008 Series Ultra-small Tuning Fork Crystal in a Smart Ring

New 1.0 x 0.8 mm surface mount crystal delivers real-time clock timing for smart rings, smartwatches, hearables, and wearable medical devices

Wearable designers are under constant pressure to shrink product while adding features and extending battery life. The RT1008 gives them the board space for features that set their products apart.” ”

— Sasha Wolloch, President of Raltron

MIAMI, FL, UNITED STATES, November 10, 2026 /EINPresswire.com/ -- Raltron, a leader in frequency control components, wireless antenna products, and high-quality audio components, today announced the RT1008 series, an ultra-small 32.768 kHz surface mount tuning fork crystal designed for wearable applications. Measuring 1.0 x 0.8 mm with an ultra-thin 0.4 mm profile, the RT1008 gives designers a dependable real-time clock (RTC) reference for products where every square millimeter of board space and height matters.

Wearables fit processors, wireless antennas, sensors, and batteries into enclosures that leave little room for supporting components. At 1.0 x 0.8 mm, the RT1008's footprint frees PCB space for larger batteries, additional sensors, or slimmer form factors.

The 32.768 kHz crystal serves as the low-frequency timing source behind timekeeping, sleep-mode wake-up, and Bluetooth Low Energy connection timing in battery-powered devices. The -40°C to +85°C operating range supports devices worn outdoors, during exercise, or in clinical settings.

The RT1008 is ideally suited for:
• Smart rings and smartwatches
• Fitness and activity trackers
• Hearables and wireless earbuds
• Wearable medical monitors and patches
• Bluetooth Low Energy and IoT modules
• Other compact, battery-powered consumer devices

“Wearable designers are under constant pressure to shrink the product while adding features and extending battery life,” said Sasha Wolloch, President of Raltron. “The RT1008 gives them the board space they need for features that set their products apart.”

The RT1008 series is available through Raltron's worldwide network of representatives and franchised distributors, with samples and application engineering support available.
