ABM3BN-32.000MHZ-18-K4Z-T

Crystals Overview

The ABM3BN-32.000MHZ-18-K4Z-T is a parallel fundamental quartz crystal oscillator manufactured by Abracon LLC. It operates at a nominal frequency of 32 MHz with a load capacitance of 18 pF and an equivalent series resistance (ESR) of 50 Ohms. The component features a frequency tolerance of ±30 ppm and a total stability of ±50 ppm across the operating temperature range of -40°C to +125°C. It utilizes a surface-mount package with four pins, designed for high-reliability applications requiring precise timing in industrial environments.

Crystals Feature Summary

• High reliability ceramic package with metal lid
• Suitable for solder reflow processes
• Fundamental mode operation for high precision

Crystals Applications

• Industrial control systems
• Communication equipment
• Test and measurement devices

Crystals Procurement Notes

Verify that the specified ESR of 50 Ohms matches the circuit design requirements, as this differs from standard variants. Confirm the wide temperature range capability (-40°C to +125°C) aligns with the target application environment. Ensure the 18 pF load capacitance is compatible with the host oscillator circuit to maintain the specified ±50 ppm stability.

Crystals Selection Notes

Select this component when a fundamental mode crystal is required for frequencies up to 50 MHz with robust industrial temperature performance. The 50 Ohm ESR indicates suitability for specific driver strength configurations. Consider the 32 MHz nominal frequency for standard clocking needs where ±30 ppm initial tolerance is sufficient. The SMD form factor supports automated assembly in dense PCB layouts.

Crystals Part Context

This part belongs to the ABM3BN series, which represents a specialized variant within Abracon's broader ABM3B family. While sharing the 5032 SMD footprint, the 'N' suffix denotes specific electrical characteristics, such as the 50 Ohm ESR and extended temperature stability, distinguishing it from standard commercial-grade counterparts. It serves as a bridge between general-purpose crystals and higher-cost oven-controlled oscillators.

Crystals Replacement Considerations

Direct substitutes must match the 32 MHz frequency, 18 pF load capacitance, and 50 Ohm ESR. Verify that alternative parts support the -40°C to +125°C operating range and offer comparable ±50 ppm stability. Cross-reference pinout compatibility for the 4-pin SMD package.
