Raltron launches RT1008 32.768 kHz crystal for wearable electronics
Raltron has introduced its RT1008 series, an ultra-compact 32.768 kHz surface-mount tuning fork crystal designed to meet the space and performance demands of modern wearable electronics. Measuring just 1.0 x 0.8 mm, with an ultra-low profile of 0.4 mm, the RT1008 provides a reliable real-time clock (RTC) reference for applications where PCB space and component height are at a premium.
As wearable devices become increasingly sophisticated, designers face the challenge of integrating processors, wireless connectivity, sensors and batteries into ever-smaller enclosures. The RT1008 addresses this challenge with its exceptionally compact footprint, helping to free up valuable printed circuit board (PCB) space for additional functionality, larger batteries or slimmer product designs.
Operating at a frequency of 32.768 kHz, the crystal provides a low-frequency timing reference essential for accurate timekeeping, sleep-mode wake-up functions and Bluetooth Low Energy (BLE) connectivity in battery-powered devices. Its operating temperature range of -40°C to +85°C also makes it suitable for products exposed to varying environmental conditions, including outdoor wearables, fitness devices and medical monitoring equipment.
Designed for a wide range of wearable and IoT applications
The Raltron RT1008 series is ideally suited to a variety of space-constrained electronic designs, including:
Smart rings and smartwatches
Fitness trackers and activity monitors
Hearables and wireless earbuds
Wearable medical monitors and patches
Bluetooth Low Energy (BLE) and IoT modules
Other compact, battery-powered consumer electronics
“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.”
Availability and technical support
The RT1008 series is available through Raltron’s worldwide network of representatives and franchised distributors. Product samples and application engineering support are also available to assist designers with integration into their electronic applications.
