C3E-40.000-12-1530-X-R

Crystals Overview

The C3E-40.000-12-1530-X-R is a parallel resonance fundamental mode quartz crystal oscillator manufactured by Aker Technology Corp. It operates at a nominal frequency of 40 MHz with a load capacitance of 12 pF and a maximum equivalent series resistance of 50 Ohms. The component features a ±15 ppm frequency tolerance at 25°C and ±30 ppm stability over the operating temperature range of -40°C to +85°C. Designed for surface mount applications, it utilizes a 4-pin SMD package measuring 3.2 mm in length, 2.5 mm in width, and 0.75 mm in height.

Crystals Procurement Notes

Verify the specific manufacturer datasheet to confirm electrical parameters such as ESR and load capacitance match circuit requirements. Ensure the ordering suffix corresponds to the desired packaging configuration. Confirm RoHS compliance status if required by assembly standards. Cross-reference the part number with official distributor catalogs to validate current availability and authenticity before procurement.

Crystals Selection Notes

Select this component when a fundamental mode crystal is required for 40 MHz applications with moderate stability needs. The 12 pF load capacitance must align with the oscillator circuit design. Consider the ±15 ppm initial tolerance and ±30 ppm temperature stability against system timing accuracy requirements. The 50 Ohm ESR limit should be compatible with the driving amplifier capabilities.

Crystals Part Context

This part belongs to the C3E series of surface mount quartz crystals from Aker Technology Corp. The series offers various frequency options and load capacitances tailored for compact electronic designs. The C3E designation indicates a standard fundamental mode crystal optimized for general commercial and industrial electronics requiring reliable timing signals.

Crystals Replacement Considerations

Direct substitutes include other 40 MHz fundamental SMD crystals with matching 12 pF load capacitance and similar physical dimensions. Verify that alternative parts meet the same ±15 ppm tolerance and 50 Ohm ESR specifications. Ensure replacement components support the -40°C to +85°C operating temperature range.
