0132M4-21.405F20DTNJK

Overview

The 0132M4-21.405F20DTNJK is a surface-mount quartz crystal manufactured by Suzhou Hangjing Elec&Tech Co., Ltd. It operates at a fundamental frequency of 21.405 MHz with a load capacitance of 20 pF. The component features an equivalent series resistance (ESR) of 100 Ohms and a frequency tolerance of ±10 ppm. It is housed in a 4-SMD, no-lead package with dimensions of 3.20mm x 2.50mm. The device supports an operating temperature range from -40°C to +85°C and is supplied in tape and reel packaging for automated assembly processes.

Feature Summary

• Surface-mount design suitable for automated pick-and-place manufacturing
• Quartz resonator providing stable frequency control
• Wide industrial temperature rating for reliable operation

Applications

• Microcontroller clock sources
• Communication module timing circuits
• Digital signal processing systems

Procurement Notes

Verify the specific frequency tolerance and ESR requirements against the target circuit design before procurement. Confirm that the 4-SMD no-lead package footprint matches the PCB layout constraints. Ensure the supplier provides traceability documentation consistent with the manufacturer's specifications for quality assurance purposes.

Selection Notes

Select this component when a 21.405 MHz reference is required in a compact surface-mount form factor. Consider the 20 pF load capacitance compatibility with the oscillator circuit's internal or external capacitors. Evaluate the ±10 ppm tolerance against system jitter requirements and ensure the 100 Ohm ESR aligns with the driving strength limits of the host oscillator.

Part Context

This part belongs to the 0132M4 series of quartz crystals produced by Suzhou Hangjing Elec&Tech Co., Ltd. The series focuses on standard SMD packages for general-purpose frequency control. Similar parts in the lineup vary primarily by frequency value while maintaining consistent package dimensions and mounting styles for design flexibility.

Replacement Considerations

Direct substitutes must match the 21.405 MHz frequency, 20 pF load capacitance, and 3.20mm x 2.50mm package size. Verify that alternative manufacturers offer comparable ESR and tolerance specifications to ensure electrical equivalence without redesigning the oscillator circuit.
