R2016-48.000-6-F-5050-TR

Crystals Overview

The R2016-48.000-6-F-5050-TR is a surface-mount quartz crystal resonator manufactured by Raltron Electronics, housed in a compact 2.0 x 1.6 mm (2016) SMD package with four terminals. It operates at a nominal frequency of 48 MHz using fundamental mode oscillation. The component features a load capacitance of 6 pF and an equivalent series resistance (ESR) of 60 Ohms maximum. Frequency tolerance is specified at ±50 ppm at 25°C, with a total frequency stability of ±50 ppm across the operating temperature range of -10°C to +60°C. The unit is supplied in tape and reel packaging for automated surface-mount assembly.

Crystals Feature Summary

• Fundamental mode AT-cut quartz construction ensures simple circuit design without harmonic matching requirements.
• Compact 2016 footprint supports high-density PCB layouts for space-constrained industrial and consumer devices.
• Low load capacitance of 6 pF reduces power consumption and facilitates compatibility with low-power IoT microcontrollers.
• Standard EIA-481 tape and reel packaging enables direct integration into automated SMT production lines.

Crystals Applications

• Clock source for USB 2.0 peripheral interfaces
• Reference clock for 10/100 Mbps Ethernet PHY transceivers
• System clock generation for general-purpose microcontrollers
• Timing reference for Bluetooth and wireless communication modules

Crystals Procurement Notes

Verify that the specific part number matches the required load capacitance of 6 pF, as this differs from standard 10 pF or 20 pF components. Ensure the operating temperature range of -10°C to +60°C aligns with the target application environment, as wider industrial ranges require different suffixes. Confirm that the 48 MHz frequency is compatible with the host oscillator circuit's input impedance and drive level specifications to prevent over-driving the crystal.

Crystals Selection Notes

Select this component when board space is limited and a 48 MHz fundamental frequency is required for standard digital interfaces. The 6 pF load capacitance necessitates careful calculation of PCB stray capacitance during layout; external matching capacitors must be sized accordingly to maintain frequency accuracy. This model is suitable for indoor consumer electronics and light industrial applications where the -10°C to +60°C range is sufficient. For environments requiring wider thermal stability, consult alternative models with extended temperature ratings.

Crystals Part Context

This component belongs to the Raltron R2016 series of surface-mount crystals, designed for applications demanding small form factors. The series utilizes fundamental mode AT-cut quartz elements to provide stable timing signals. The 2016 package size represents a significant reduction compared to traditional through-hole or larger SMD crystals, allowing for denser circuit board designs in modern portable and embedded electronic systems.

Crystals Replacement Considerations

Direct substitutes must match the 48 MHz frequency, 6 pF load capacitance, and 2016 package dimensions. Verify that alternative manufacturers offer components with comparable ESR limits and frequency stability within the -10°C to +60°C range. Ensure any replacement maintains the same pin configuration and soldering profile to avoid reflow process adjustments.
