Overview
The CI08E-05S270-C-1 is an electromagnetic surface mount indicator manufactured by Challenge Electronics. It features a compact footprint of 8.5 mm x 8.5 mm with a height of 3.6 mm. The device operates at a rated voltage of 3.0 VDC and produces a sound pressure level of 82 dB at the rated voltage. Its resonant frequency is specified at 2,700 Hz. The component utilizes side emission for audio output and is designed for ASIC indicator applications.
Feature Summary
- Compact surface mount design suitable for space-constrained PCB layouts
- Electromagnetic transducer technology for reliable audio signaling
- Side-emission configuration for directed acoustic output
Applications
- ASIC indicator circuits
- Low-cost transducer applications
- Electronic equipment requiring audible status feedback
Procurement Notes
Verify the specific datasheet version to confirm mechanical tolerances and soldering profile requirements. Ensure the operating voltage aligns with the 3.0 VDC rating to maintain the specified 82 dB performance level. Check for any RoHS compliance documentation if required by your manufacturing standards. Confirm lead times as they may vary based on production schedules.
Selection Notes
Select this component when a low-profile electromagnetic indicator is needed for surface mount assembly. The 8.5 mm square form factor allows for dense board placement. Consider the 2,700 Hz resonant frequency to ensure adequate audibility in the target environment. Verify that the side-emission direction matches the enclosure design for optimal sound projection.
Part Context
This part belongs to Challenge Electronics' line of electromagnetic indicators and transducers. It is categorized as a low-cost solution for audio signaling needs. The series includes various sizes and mounting options, with this specific model focusing on small-footprint surface mount integration for modern electronic devices.
Replacement Considerations
Check for direct substitutes within the Challenge Electronics CI series that match the 8.5 mm x 8.5 mm footprint and 3.0 VDC rating. Ensure any replacement maintains the 82 dB SPL and similar resonant frequency characteristics. Verify pinout compatibility if the new component has different terminal configurations.
