Product details
Overview
VXM7-1366-48M0000000 from Vectron is a 48.000 MHz fundamental-mode AT-cut quartz crystal resonator in a 3.2 × 2.5 mm SMD package, rated for -40 °C to +85 °C operation with ±10 ppm frequency stability and 12 pF load capacitance, used as a precision timing reference in wireless transceivers and industrial microcontrollers.
For engineers reviewing the VXM7-1366-48M0000000 datasheet, VXM7-1366-48M0000000 pinout, VXM7-1366-48M0000000 application, or VXM7-1366-48M0000000 equivalent, key selection criteria include operating temperature range, frequency tolerance, load capacitance matching, ESR limit, and RoHS-compliant reflow profile compatibility.
Technical Context
This 48 MHz crystal operates in fundamental mode using an AT-cut quartz blank, optimized for stable oscillation under industrial temperature extremes. Its 12 pF load capacitance requires matching external capacitors in the oscillator circuit, and its 40 Ω max ESR ensures reliable start-up with standard CMOS oscillator ICs.
The device complies with MIL-STD-883 mechanical shock/vibration and temperature cycle tests, supports Pb-free reflow (MSL 1), and features gold-plated Ni underlayer contact pads compatible with both SnPb and lead-free soldering processes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar crystal resonator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ABM3B-48.000MHZ-B2-T | Same 3.2 × 2.5 mm footprint, ±10 ppm stability, but 18 pF load capacitance | Requires redesign of external load caps; not drop-in for 12 pF oscillator circuits | Select only if board layout allows capacitor value change and oscillator IC supports 18 pF CL |
| QXO325-48.000M | Higher ESR (60 Ω max), same temp range and tolerance, but no MIL-STD-883 qualification | Lacks shock/vibration validation for industrial motion control or transportation systems | Acceptable for consumer-grade applications where mechanical stress testing is not required |
Compared with ABM3B-48.000MHZ-B2-T and QXO325-48.000M, the VXM7-1366-48M0000000 provides tighter load capacitance matching (12 pF), lower ESR (40 Ω), and full MIL-STD-883 environmental qualification-making it optimal for timing-critical industrial and automotive control designs.

FAQ
What is the nominal frequency and tolerance of the VXM7-1366-48M0000000?
The VXM7-1366-48M0000000 has a nominal frequency of 48.000 MHz with a frequency tolerance of ±10 ppm at 25 °C. This tolerance reflects the initial calibration accuracy before aging or temperature effects, and is verified per the manufacturer's standard test conditions defined in Table 1 of the datasheet.
Does the VXM7-1366-48M0000000 require external load capacitors, and what value is needed?
Yes, the VXM7-1366-48M0000000 requires two external load capacitors-one on each crystal pin-to match its specified 12 pF load capacitance. The actual capacitor value depends on PCB stray capacitance; typical design uses two 22 pF NP0/C0G capacitors to achieve ~12 pF effective CL in standard layouts.
What is the maximum ESR specification for the VXM7-1366-48M0000000, and why does it matter?
The VXM7-1366-48M0000000 has a maximum equivalent series resistance (ESR) of 40 Ω at 48 MHz. This low ESR ensures sufficient negative resistance margin for reliable oscillator start-up and sustained oscillation, especially with low-power microcontrollers and integrated oscillator circuits that provide limited drive strength.
Is the VXM7-1366-48M0000000 compatible with lead-free reflow soldering processes?
Yes, the VXM7-1366-48M0000000 is fully compatible with Pb-free reflow soldering and is rated MSL 1 (unlimited floor life). Its gold-over-nickel contact pads meet J-STD-020 requirements, and the recommended reflow profile specifies peak temperature ≤260 °C for ≤30 seconds, matching standard Class 3 assembly guidelines.
What environmental qualifications does the VXM7-1366-48M0000000 meet?
The VXM7-1366-48M0000000 meets MIL-STD-883 mechanical shock (Method 2002, Condition B), vibration (Method 2007, Condition A), temperature cycling (Method 1010, Condition B), and gross/fine leak (Method 1014) standards. These qualifications validate its suitability for high-reliability applications in industrial automation and transportation equipment.
