CS00546-26M

Overview

The CS00546-26M is a 26.0000 MHz fundamental mode quartz crystal manufactured by NDK (NIHON DEMPA KOGYO CO., LTD). It features a frequency stability and tolerance of ±10ppm with a load capacitance of 10pF. The component operates within a temperature range of -20°C to +70°C and has an equivalent series resistance (ESR) of 50 Ohms maximum. It is housed in a compact 4-SMD, No Lead package with dimensions of 3.2mm x 2.5mm x 1.0mm. This device is RoHS compliant and designed for surface mount applications.

Feature Summary

• Provides excellent environmental resistance against heat, vibration, and shock
• Designed specifically for automotive applications requiring high reliability
• Supports mobile communication and OA/AV variant requirements

Applications

• Automotive electronic systems
• Mobile communication devices
• Office Automation (OA) equipment
• Audio/Video (AV) systems

Procurement Notes

Verify the specific load capacitance requirement of your circuit design against the component's 10pF specification to ensure accurate frequency operation. Confirm that the operating temperature range of -20°C to +70°C aligns with your application's environmental conditions. Ensure the PCB footprint matches the 4-SMD, No Lead package dimensions of 3.2mm x 2.5mm. Check for RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when a 26 MHz reference signal is required for automotive or consumer electronics. Consider its superior shock and vibration resistance compared to standard crystals. Evaluate the 10pF load capacitance compatibility with your oscillator circuit. The compact SMD form factor makes it suitable for space-constrained designs in mobile and AV applications.

Part Context

This part belongs to NDK's line of surface mount quartz crystals. It is distinct from other variants like CS00445-26M which may have different load capacitance or ESR values. The CS00546-26M is specifically engineered for robustness in harsh environments, distinguishing it from general-purpose oscillators.

Replacement Considerations

CS00445-26M is a documented substitute from the same manufacturer. Verify that the alternative part meets the same 26 MHz frequency, ±10ppm stability, and 10pF load capacitance requirements. Ensure the replacement maintains the 4-SMD package size and automotive-grade environmental resilience.
