Product details
Overview
VXM7-9022-12M0000000 from Vectron is a 3.2 × 2.5 mm surface-mount quartz crystal operating at 12.0000 MHz fundamental mode with ±30 ppm frequency tolerance, ±50 ppm stability over −40 °C to +85 °C, and 12 pF load capacitance - designed for timing reference in Microchip 32-bit MCU systems.
For engineers reviewing the VXM7-9022-12M0000000 datasheet, VXM7-9022-12M0000000 pinout, VXM7-9022-12M0000000 application, or VXM7-9022-12M0000000 equivalent, key selection criteria include load capacitance matching, aging performance (±5 ppm/year), ESR (≤100 Ω), RoHS compliance, and reflow profile compatibility (MSL 1, peak 260 °C).
Technical Context
This is a passive AT-cut fundamental-mode quartz crystal resonator requiring external oscillator circuitry - not an active oscillator IC. It delivers stable frequency generation only when integrated into a Pierce oscillator configuration with appropriate load capacitance and drive level control (0.01–100 µW).
Its mechanical construction meets MIL-STD-883 environmental test standards including shock, vibration, temperature cycling, and gross/fine leak testing. Gold-plated contact pads (≥0.2 µm) ensure solderability under lead-free reflow conditions per Table 3 profile.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Frequency | 12.0000 MHz - exact fundamental oscillation frequency at 25 °C, used as system clock reference for Microchip MCUs. |
| Frequency Tolerance | ±30 ppm - maximum initial deviation from nominal frequency at 25 °C, critical for UART/USB timing margin. |
| Stability Over Temp | ±50 ppm - total frequency variation across −40 °C to +85 °C operating range, defines worst-case timing error in industrial environments. |
| Load Capacitance | 12 pF - required external capacitive load for accurate frequency calibration; must match PCB layout and MCU oscillator circuit design. |
| ESR | 100 Ω max - series resistance affecting start-up reliability and phase noise; low value supports robust oscillation with low-power MCUs. |
| Aging (1st year) | ±5 ppm - long-term drift at 25 °C, impacts timekeeping accuracy in battery-powered or uncalibrated systems over extended deployment. |
| Operating Temp Range | −40 °C to +85 °C - qualified for industrial-grade embedded applications without thermal compensation. |
Pinout & Package
Package: 3.2 mm × 2.5 mm × 0.7 mm ceramic SMD package (four-pad, metalized bottom termination). Two terminals only: Terminal 1 (anode-side pad) and Terminal 2 (cathode-side pad), electrically symmetric - no polarity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Crystal electrode | Connects to MCU XTAL1 or OSC1 input; forms one side of resonant loop in Pierce oscillator. |
| Terminal 2 | Crystal electrode | Connects to MCU XTAL2 or OSC2 output; completes resonant path with internal inverter and load caps. |
Key Features
| Feature | Design Value |
|---|---|
| Fundamental AT-cut mode | Enables reliable 12 MHz operation without overtone circuit complexity or spurious mode risk. |
| ±30 ppm initial tolerance | Reduces need for factory calibration in cost-sensitive MCU-based consumer and industrial controls. |
| MSL 1 rating | Allows unlimited floor life and single-reflow processing without dry-pack or baking requirements. |
| Gold-plated contacts (≥0.2 µm) | Ensures consistent solder wetting and intermetallic formation in Pb-free SAC305 reflow profiles. |
| MIL-STD-883 qualified | Validates mechanical robustness for automotive under-hood, industrial motor drives, and outdoor IoT deployments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar crystal resonator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ABM3B-12.000MHZ-B2-T | Same 3.2 × 2.5 mm footprint, ±20 ppm tolerance, 10 pF load capacitance, 80 Ω ESR. | Better initial accuracy but requires PCB capacitor adjustment to match 10 pF CL; tighter tolerance unnecessary for most MCU clocking. | Select if system-level timing budget demands <±20 ppm initial error and layout allows CL recalculation. |
| Q14M12000000000 | Identical 12.0000 MHz, ±30 ppm, 12 pF, −40/+85 °C, but 1.6 × 1.2 mm size and 150 Ω ESR. | Smaller footprint saves board space but higher ESR risks marginal start-up in low-drive MCU configurations. | Select only after validating oscillator loop gain margin with target MCU's XTAL driver strength. |
Compared with ABM3B-12.000MHZ-B2-T and Q14M12000000000, VXM7-9022-12M0000000 offers balanced trade-offs: industry-standard 12 pF load matching, proven 100 Ω ESR compatibility with Microchip MCUs, and MIL-qualified reliability - making it optimal for volume industrial designs where qualification effort and supply continuity matter more than marginal spec improvements.

FAQ
What is the load capacitance requirement for VXM7-9022-12M0000000?
VXM7-9022-12M0000000 requires a 12 pF load capacitance to operate at its specified nominal frequency of 12.0000 MHz. This value must be realized by the sum of external PCB capacitors, MCU internal capacitance (if any), and stray capacitance. Deviations will shift actual frequency - always verify with network analyzer or frequency counter during prototype validation. VXM7-9022-12M0000000 is not internally compensated and relies entirely on external LC network tuning.
Is VXM7-9022-12M0000000 compatible with lead-free reflow processes?
Yes, VXM7-9022-12M0000000 is fully compatible with lead-free reflow, rated MSL 1 with no floor-life limitation. Its gold-plated contacts (≥0.2 µm over nickel) meet J-STD-020 requirements, and the recommended profile specifies peak temperature ≤260 °C for ≤30 seconds. VXM7-9022-12M0000000 has been validated per Microchip's reflow table with ramp rates ≤3 °C/sec up and ≤6 °C/sec down.
Does VXM7-9022-12M0000000 include built-in temperature compensation?
No, VXM7-9022-12M0000000 is a standard AT-cut fundamental-mode quartz crystal without temperature compensation. Its frequency stability over temperature is ±50 ppm across −40 °C to +85 °C, achieved solely through crystal cut and manufacturing process - not TCXO circuitry. For improved thermal stability, a separate TCXO or oven-controlled solution would be required; VXM7-9022-12M0000000 itself provides no active compensation.
What is the maximum drive level specification for VXM7-9022-12M0000000?
VXM7-9022-12M0000000 has a maximum drive level of 100 µW, with typical operation between 0.01 µW and 10 µW. Exceeding 100 µW risks accelerated aging or crystal fracture. MCU oscillator circuits must be configured to limit power dissipation - verify drive level using current probe or oscilloscope measurement at crystal terminals. VXM7-9022-12M0000000 datasheet specifies this limit under "Electrical Performance" Table 1.
Can VXM7-9022-12M0000000 be used with non-Microchip microcontrollers?
Yes, VXM7-9022-12M0000000 is a generic 12 MHz fundamental-mode crystal and can be used with any MCU supporting external crystal oscillators, provided the load capacitance (12 pF), ESR (≤100 Ω), and drive level (<100 µW) are met. However, its qualification testing and application notes focus on Microchip 32-bit MCUs - interoperability with other vendors' parts must be verified per their oscillator design guidelines. VXM7-9022-12M0000000 does not contain vendor-specific firmware or logic.
