403WF48012IVR

Crystals Overview

The 403WF48012IVR is a surface-mount quartz crystal resonator manufactured by CTS-Frequency Controls. It operates at a fundamental frequency of 48 MHz with a load capacitance of 7 pF and an equivalent series resistance (ESR) of 35 Ohms. The device features a frequency tolerance of ±10 ppm and is housed in a compact 4-SMD, No Lead package measuring 3.2 mm x 2.5 mm. Designed for IoT applications, it provides stable frequency generation for microcontroller systems.

Crystals Feature Summary

• Compact 3.2mm x 2.5mm surface-mount footprint suitable for space-constrained designs
• Optimized for Internet of Things (IoT) enhanced quartz applications
• Stable frequency performance with ±10 ppm tolerance at 48 MHz

Crystals Applications

• Internet of Things (IoT) sensor nodes
• Microcontroller unit (MCU) clock sources
• Wireless communication modules requiring 48 MHz timing

Crystals Procurement Notes

Verify the specific ordering suffix IVR against the manufacturer's current datasheet to confirm package variant and tape-and-reel specifications. Ensure compatibility with reflow soldering profiles defined for 4-SMD no-lead components. Cross-reference the 7pF load capacitance requirement with the target oscillator circuit design to guarantee accurate frequency stability.

Crystals Selection Notes

Select this component when a 48 MHz reference is required for IoT-centric embedded systems. The 35 Ohm ESR and 7pF load capacitance must match the host MCU's internal oscillator parameters. Consider the 3.2mm x 2.5mm dimensions for PCB layout constraints where larger crystals are unsuitable. Validate thermal stability requirements against the standard operating range specified in the official documentation.

Crystals Part Context

This part belongs to the 403W series of enhanced quartz crystals from CTS-Frequency Controls. The series targets modern low-power and high-density electronics, specifically addressing the needs of IoT devices. The 48 MHz frequency is common for wireless protocols and high-speed data processing interfaces.

Crystals Replacement Considerations

Direct substitutes include other 48 MHz crystals in 3225 packages with matching 7pF load capacitance and ≤35 Ohm ESR. Verify that alternative parts support the same ±10 ppm tolerance and surface-mount reflow processes. Check for identical mounting pad layouts to ensure mechanical interchangeability without PCB redesign.
