CS15191-30M

Overview

The CS15191-30M is a surface-mount crystal unit manufactured by NDK, designed for automotive applications. It operates at a fundamental frequency of 30 MHz with a frequency stability and tolerance of ±15ppm. The component features an 8pF load capacitance and an equivalent series resistance (ESR) of 50 Ohms. It utilizes a 4-SMD, no-lead package with dimensions of 3.20mm x 2.50mm x 0.60mm maximum height. The device supports base harmonic operation and functions within a temperature range of -10°C to 75°C.

Feature Summary

• Provides excellent environmental characteristics including heat, vibration, and shock resistance specifically engineered for automotive use.

Applications

• Automotive electronic systems requiring high reliability
• Timing circuits in vehicle control units
• Communication interfaces in automotive environments

Procurement Notes

Verify the specific ordering suffix against the official NDK datasheet STD-CSR-3 to ensure correct packaging and specifications. Confirm that the required frequency stability and load capacitance match the system design requirements. Check RoHS3 compliance status if environmental regulations apply to the final assembly. Ensure the surface-mount footprint aligns with the PCB layout guidelines provided in the manufacturer's documentation.

Selection Notes

Select this component when automotive-grade durability against thermal and mechanical stress is required. The 30 MHz frequency and ±15ppm stability suit general timing needs where extreme precision is not critical. The compact 3.2x2.5mm package allows for space-constrained designs. Consider the -10°C to 75°C operating range to ensure functionality within the intended environment.

Part Context
