EFO-MC4004A4

Resonators Overview

The EFO-MC4004A4 is a ceramic resonator manufactured by Panasonic Electronic Components, designed for through-hole mounting. It operates at a nominal frequency of 4 MHz with an initial frequency tolerance of ±0.5% and stability of ±0.3%. The device features built-in capacitors to facilitate Colpitts oscillation circuits without external components. It supports a temperature range of -20°C to +80°C and has a maximum height of 5.00 mm. The package is a radial box type with three leads spaced at 2.50 mm.

Resonators Feature Summary

• Integrates two internal capacitors to construct Colpitts oscillation circuits, eliminating the need for external capacitors in the oscillator design.

Resonators Applications

• Clock pulse generator for microprocessors
• Carrier applications in telecommunication equipment

Resonators Procurement Notes

Verify the specific suffix 'A4' against the official Panasonic datasheet to confirm lead configuration and packaging details. Ensure the procurement channel provides valid RoHS compliance documentation. Cross-reference the part number with current Panasonic product status notices, as availability may vary based on production lifecycle updates.

Resonators Selection Notes

Select this component when a cost-effective, high-stability clock source is required for microprocessor systems. The built-in capacitor feature simplifies PCB layout by reducing component count. Verify that the operating environment falls within the specified -20°C to +80°C range to maintain the stated frequency stability and tolerance specifications.
