EFO-JM3205E5

Resonators Overview

The EFO-JM3205E5 is a surface-mount ceramic resonator from the Panasonic EFO-JM series. It operates at a nominal frequency of 32 MHz with a frequency stability of ±0.2% and a tolerance of ±0.5%. The device features an integrated load capacitance of 10 pF, eliminating the need for external capacitors in typical circuit designs. It is housed in a non-standard 3-SMD package measuring 4.40mm x 3.60mm x 1.19mm. The component supports operation within a temperature range of -20°C to +80°C and utilizes a tape and reel packaging format.

Resonators Procurement Notes

Verify current availability status as this component is listed as obsolete or discontinued by the manufacturer. Confirm compatibility with existing PCB footprints and reflow soldering profiles before procurement planning. Check for valid substitute part numbers if production continuity is required.

Resonators Selection Notes

Select this component when a stable 32 MHz reference is needed without external tuning components. Ensure the operating environment stays within the specified -20°C to +80°C range. Verify that the ±0.2% stability meets system timing requirements compared to standard crystal oscillators.

Resonators Part Context

This part belongs to the EFO-JM series of ceramic resonators designed for general-purpose digital circuits. It serves as a cost-effective alternative to quartz crystals where high precision is not critical. The series is characterized by built-in capacitors and SMD packaging for easy integration into consumer electronics.

Resonators Replacement Considerations

Public confirmed substitute part numbers include PX320JTR-ND and PX320JCT-ND. These are equivalent ceramic resonators with identical electrical specifications and pin configurations suitable for direct replacement in existing designs.
