Crystals Procurement Notes

Verify the exact load capacitance requirement against the host circuit design, as variants within this series may differ (e.g., 8pF vs 10pF). Confirm the 'IKR' suffix corresponds to the required tape and reel packaging format for automated placement. Ensure the ±10 ppm stability meets the system's jitter and phase noise specifications. Cross-reference the datasheet for specific storage temperature limits and soldering thermal profiles to prevent mechanical stress during assembly.

Crystals Selection Notes

Select this component when a 48 MHz frequency with tight ±10 ppm stability is required for digital logic or DSP applications. The 8 pF load capacitance must match the oscillator circuit's input capacitance to ensure accurate frequency generation. Consider the 60 Ohm ESR limit for driver strength compatibility. The 4-SMD no-lead package offers space efficiency compared to through-hole alternatives. Verify that the operating temperature range covers the intended environmental conditions.

Crystals Part Context

This part belongs to the CTS 402 series of surface-mount crystals, widely used in consumer electronics and industrial control systems.
