Find crystals for MCUs, communication modules and timekeeping circuits by frequency, load capacitance and package.
A quartz crystal works with an oscillator circuit inside or outside the host IC. Selection goes beyond frequency and size: review load capacitance, equivalent series resistance (ESR), drive level and operating temperature.
Package concept, not the outline or marking of a specific part.
Expand a category to see its series, or search by model, package or interface.

| Parameter | Information to specify |
|---|---|
| Nominal frequency & vibration mode | Exact frequency; fundamental or overtone |
| Load capacitance CL | Match the host circuit, not just the footprint |
| ESR & drive level | Check start-up margin and maximum drive |
| Tolerance, temperature & aging | Specify initial tolerance, temperature stability and aging separately |
MCUs / IoT modules / RTC timekeeping / industrial control
These are selection topics; suitability depends on the part and application validation.
Not on those two attributes alone. CL, ESR, drive level, pads and temperature ratings may differ. Review the specifications and validate the replacement in the target circuit.
Read technical resources ↗When a project needs a less common frequency, MERLIN can discuss options through multiple brands and domestic manufacturing partner resources. Feasibility, minimum order and delivery are confirmed against the specific frequency, package and electrical requirements.
See what to prepare →Prototypes, pilot runs and production orders can have different conditions. MERLIN discusses samples and flexible volumes by project, aligning the validation purpose with part-specific minimum orders, packaging and delivery.
See what to prepare →When an international part needs an alternative, compare specifications before application validation. MERLIN works with actual manufacturing resources including SCTF and CREC to discuss domestic candidates, differences and sample requirements.
See what to prepare →A 5-minute response. Less waiting, more progress
Brand, frequency, quantity and delivery target — a useful place to start.
