Overview
The QT216S-48.000MDIY-T is a surface-mount crystal oscillator manufactured by QST, designed for precision timing applications. It operates at a fundamental frequency of 48.000 MHz with a standard tolerance of ±30 ppm. The component features an 8 pF load capacitance and a maximum series resistance of 50 Ohms. Housed in a compact 4-SMD, No Lead package, this device provides stable clock signals for digital circuits while maintaining low profile requirements suitable for modern PCB layouts.
Feature Summary
- Provides precise 48 MHz clock signal generation
- Compact surface-mount design for space-constrained boards
- Low series resistance for efficient circuit integration
Applications
- Microcontroller clock sources
- Communication interface timing
- Digital logic synchronization
Procurement Notes
Verify the specific suffix 'DIY' against official QST documentation to confirm exact frequency stability and load capacitance specifications. Ensure the 4-SMD no-lead package matches your assembly capabilities. Cross-reference the manufacturer's latest datasheet for reflow soldering profiles and storage conditions to maintain component integrity during production.
Selection Notes
Select this component when a 48 MHz reference is required for synchronous digital systems. The 50 Ohm series resistance limit suits most standard oscillator circuits. Consider the 8 pF load capacitance requirement to ensure accurate frequency matching with the host circuit's capacitive load. Verify temperature stability needs against the standard commercial range if operating in extreme environments.
Part Context
This part belongs to QST's line of surface-mount crystals, offering reliable timing solutions for consumer and industrial electronics. The 4-SMD form factor allows for automated placement, enhancing manufacturing efficiency. It serves as a critical passive component in timing networks, replacing larger through-hole alternatives in high-density designs.
Replacement Considerations
Check QST's official substitution guide for direct equivalents. Generic 48 MHz crystals may differ in load capacitance or ESR. Ensure any substitute matches the 4-SMD no-lead footprint and electrical parameters to avoid re-spreading.
