The **M3A11FBA-R** is an electronic component primarily associated with the **M3A series** of Crystal Oscillators manufactured by companies like **NDK (Nihon Dempa Kogyo)** or similar high-precision timing component manufacturers. These parts are critical for providing a stable clock signal in digital circuits. --- ### 1. Key Technical Specifications The "M3A" prefix typically denotes a specific package size and output type (often HCMOS). Below is a breakdown of the typical specifications for this series: | Parameter | Specification (Typical) | | :--- | :--- | | **Component Type** | SPXO (Simple Packaged Crystal Oscillator) | | **Package Size** | 3.2 x 2.5 mm (SMD) | | **Output Type** | CMOS / HCMOS | | **Supply Voltage ($V_{cc}$)** | 1.8V to 3.3V (varies by sub-model) | | **Frequency Stability** | ±25ppm to ±50ppm | | **Operating Temperature** | -40°C to +85°C | --- ### 2. Functional Characteristics The M3A11FBA-R functions as the "heartbeat" of an electronic system. Its internal construction includes: * **AT-Cut Quartz Crystal:** Used for high-frequency stability and low temperature drift. * **Oscillator IC:** A low-power CMOS integrated circuit that sustains the oscillation and buffers the output. * **Standby Function:** Most models in this series feature a "Tri-state" or "Enable/Disable" function on Pin 1, allowing the output to be turned off to save power. --- ### 3. Part Number Decoder (Typical) While naming conventions vary slightly by manufacturer, the suffix codes usually break down as follows: 1. **M3A:** Series designation (3.2 x 2.5 mm form factor). 2. **11:** Internal code for voltage or frequency range. 3. **FBA:** Specifics regarding frequency stability and operating temperature range. 4. **-R:** Generally indicates **RoHS Compliant** or **Tape & Reel** packaging for automated assembly. --- ### 4. Common Applications Due to its small footprint and reliable CMOS output, this part is found in: * **Consumer Electronics:** Tablets, digital cameras, and smart home devices. * **Networking:** Ethernet switches and routers. * **Industrial:** PLCs (Programmable Logic Controllers) and sensor nodes. ---
