3.68MHz 3PIN Ceramic Resonator

1.Nominal Frequency and Accuracy: Features a nominal oscillation frequency of 3.680 MHz with a frequency accuracy of ±0.5%, providing a reliable clock reference.
2.Low Resonant Impedance: Offers a low resonant impedance of maximum 40 Ω, facilitating fast and stable start-up oscillation.
3.Thermal Stability: Exhibits a frequency drift (temperature coefficient) of maximum ±0.3% over the operating temperature range of -25℃ to +85℃.
4.Long-term Stability & Low Aging Rate: Demonstrates stable performance with a maximum aging rate of ±0.1% after a 1000-hour aging test at +85℃.
5. Operating Voltage & Insulation Resistance: Operates at a rated voltage of 6V DC / 15V p-p AC, with a minimum insulation resistance of 500 MΩ (tested at 10V DC).

The SMD 3.68MHz 3PIN ceramic resonator is a highly integrated 3-pin timing solution with built-in load capacitors, designed to serve as a direct, cost-effective replacement for the Murata CSTCC series (such as CSTCC3M68G53-R0) in microcontrollers and digital systems.

Key Features

Built-in Capacitors: The integrated loading capacitors eliminate the need for external tuning components, saving PCB space and reducing overall BOM costs.

Surface-Mount Design (SMD): Housed in a standard 6030 package (6.0×3.0×1.5 mm), enabling high-speed automated SMT pick-and-place assembly.

Highly Cost-Effective: Serves as a budget-friendly alternative to quartz crystals in applications that can tolerate a frequency tolerance of ±0.5%.

Low Resonant Impedance: A maximum resonant impedance of 40 Ω ensures reliable and fast start-up oscillation.

Excellent Thermal Stability: Operates stably across a wide temperature range of −25℃to +85 with low frequency drift (±0.3%).

RoHS Compliant: Fully complies with international RoHS directives and environmental protection regulations.

Applications

Microcontroller (MCU) Clock Sources: Widely used to provide system clock signals for microprocessors in consumer electronics, home appliances, and toys.

Smart Household Appliances: Main controller boards for air conditioners, washing machines, and microwave ovens.

Consumer Devices: Remote controllers, game pads, and basic audio/video equipment.

Industrial & Telecom: Local clock generation in low-speed communication modules, meter readers, and basic digital instruments.
