What frequency range does FCX-M1 support?

FCX-M1 covers nominal frequencies from 7 to 200 MHz.

What are the typical tolerance and stability options?

Typical frequency tolerance is ±10 ppm at 25°C ±3°C. Stability options include ±10 ppm over -20 to 70°C and ±30 ppm over -40 to 85°C (reference 25°C).

Do you support samples, mass production, and customization?

Yes. We support samples, volume production, and custom specifications (frequency, CL, tolerance, stability, temperature range, packaging, and test conditions). Contact us with your requirements for a fast RFQ.

What is the typical MOQ and lead time?

MOQ and lead time depend on frequency and specification. Please send your target frequency, CL, tolerance/stability, temperature range, and quantity for an accurate quotation and delivery schedule.

Can you provide test reports and compliance documentation?

Yes. RoHS/REACH compliance documents and relevant test information can be provided on request. If you need additional quality documentation, include it in your RFQ.

Why is there no public price on the page?

Quartz crystal pricing depends on frequency, stability, CL, temperature grade, screening, and volume. For the best offer, request an RFQ and we will respond with a tailored quote.

Applications: Where FCX-M1 Fits (and Why)

A DIP MHz crystal is often selected when you need a stable reference for a discrete oscillator or clock circuit, with easy handling for prototypes and production fixtures.

Communication equipment: Stable frequency tolerance and temperature stability help reduce channel offset and maintain predictable timing margins across environments.
Measurement & instrumentation: Aging performance and controlled drive level support repeatable calibration intervals and stable time bases.
General clock generation (MCU/SoC peripheral clocks): When paired with an IC’s internal oscillator circuit, selecting the correct CL and keeping drive level within limits improves start-up reliability and reduces stress on the resonator.

Ordering Code / Options

To quote accurately, crystals are usually specified by frequency and electrical load conditions. Provide the items below to receive a fast RFQ (samples, mass production, or custom build).

Item	What to specify	Why it matters
Frequency	Target frequency (MHz) and mode (fundamental / overtone)	Defines the resonator design; overtone impacts ESR limits and oscillator margins
Load Capacitance (CL)	10 / 18 / 20 pF or custom	Correct CL improves frequency accuracy in your oscillator circuit
Tolerance @25°C	e.g., ±10 ppm	Initial frequency offset budget
Stability over temperature	e.g., ±10 ppm (-20 to 70°C) or ±30 ppm (-40 to 85°C)	Controls drift in field conditions
Operating temperature	-40 to +85°C (or confirm your range)	Impacts stability requirement and screening
Drive level	Keep within 10 µW typ / 100 µW max	Prevents overstress; improves long-term reliability
Packaging	Bulk, tape, or special packing (if required)	Defines delivery format for production

Selection Path / Upgrade Options: If you need a different form factor or frequency range, compare related products: FCX-M5 (UM-5 MHz DIP), FCX-4U (HC-49U type), FCX-5U (50U type).
