EFJ-C3005E5B

Resonators Overview

The EFJ-C3005E5B is a surface-mount crystal oscillator manufactured by Panasonic Electronic Components. It operates at a fundamental frequency of 30 MHz with a frequency tolerance of ±0.5% and stability of ±0.2%. The device features an integrated 8 pF built-in capacitor, eliminating the need for external load components. Housed in a compact 3-SMD package measuring 2.50mm x 2.00mm with a height of 1.25mm, it supports reflow soldering processes suitable for high-density PCB layouts.

Resonators Feature Summary

• Integrated 8 pF internal capacitance simplifies circuit design
• Compact 3-SMD footprint enables dense board integration
• High frequency stability ensures reliable signal generation

Resonators Applications

• Embedded communication systems
• Mobile devices requiring compact form factors
• IoT modules with space constraints

Resonators Procurement Notes

Verify component authenticity through authorized Panasonic distributors or certified suppliers. Request official datasheets to confirm specific lot codes and manufacturing dates. Ensure storage conditions comply with manufacturer guidelines to maintain performance integrity prior to assembly.

Resonators Selection Notes

Select this component when a fixed 30 MHz output is required without external tuning capacitors. The integrated capacitance reduces bill of materials complexity. Evaluate thermal requirements against operating temperature limits before finalizing the design for harsh environments.

Resonators Part Context

This model belongs to the EFJ series of surface-mount crystal oscillators from Panasonic Electronic Components. It represents a specialized solution for applications demanding precise timing signals within minimal physical footprints, distinguishing itself from discrete crystal assemblies by including necessary load elements internally.

Resonators Replacement Considerations

Direct substitutes include the EFJ-C4005E5B variant, which offers identical packaging and functionality but operates at 40 MHz. Verify pin compatibility and frequency requirements when considering alternative frequencies within the same product family.
