402F30012IJR

Crystals Overview

The CTS-Frequency Controls 402F30012IJR is a fundamental mode MHz crystal resonator operating at 30 MHz. It features a load capacitance of 9pF and a frequency tolerance of ±10ppm, with stability rated at ±20ppm. The component exhibits an equivalent series resistance (ESR) of 80 Ohms. It utilizes a 4-SMD, no-lead package with dimensions of 2.00mm x 1.60mm and a maximum height of 0.55mm. Designed for surface mount installation, it supports an operating temperature range of -40°C to +85°C.

Crystals Feature Summary

• Fundamental oscillation mode for precise frequency generation
• Compact 4-SMD no-lead surface mount footprint
• Wide industrial temperature rating from -40°C to +85°C

Crystals Applications

• Microcontroller clock sources
• Communication module timing references
• Digital signal processing circuits

Crystals Procurement Notes

Verify the specific suffix 'JR' against the manufacturer's official datasheet to confirm package variant and tape/reel specifications. Ensure the load capacitance requirement of the target circuit matches the 9pF specification. Confirm RoHS3 compliance status if environmental regulations apply to the final assembly. Cross-reference the ESR value of 80 Ohms with oscillator circuit design requirements to ensure proper startup conditions.

Crystals Selection Notes

Select this component when a 30 MHz fundamental crystal with low profile is required. The 9pF load capacitance suits circuits with minimal stray capacitance. Consider the ±10ppm initial tolerance for applications requiring tighter frequency accuracy than standard ±20ppm parts. The 4-SMD package is suitable for high-density PCB layouts where space constraints limit component size.

Crystals Part Context

This part belongs to the CTS 402 Series of surface mount crystals. The series offers various frequencies and package sizes optimized for consumer and industrial electronics. The 402F30012IJR specifically addresses the need for a 30 MHz reference in compact designs. It shares common form factors with other members of the 402 family but differs in electrical parameters such as frequency and load capacitance.

Crystals Replacement Considerations

Direct substitutes must match the 30 MHz frequency, 9pF load capacitance, and 4-SMD(2x1.6) package. Verify that alternative components meet the same ±10ppm tolerance and 80 Ohm ESR specifications. Ensure the replacement supports the -40°C to +85°C operating range.
