K 28 WP - 50 OHM

Speakers Overview

The Visaton K 28 WP - 50 OHM is a general-purpose miniature speaker featuring a round design with a plastic diaphragm. It operates within a frequency range of 300 Hz to 20 kHz, with a self-resonant frequency of 600 Hz. The unit has an impedance of 50 Ohms and a power rating of 1 W. It delivers an efficiency of 76 dBA at 1W/1m. Dimensions are approximately 28 mm in diameter and 5.5 mm in depth.

Speakers Feature Summary

• Round miniature form factor suitable for compact installations
• Plastic diaphragm construction for balanced frequency response
• General-purpose wideband audio reproduction

Speakers Applications

• Compact audio devices requiring small footprint speakers
• Intercom systems
• Alarm indicators
• Portable electronic equipment

Speakers Procurement Notes

Verify the specific impedance value (50 Ohms) against circuit requirements to ensure proper matching. Confirm the physical dimensions (28mm diameter) fit the designated enclosure space. Check the operating temperature range if the application involves extreme environmental conditions. Ensure the solder pad or terminal type matches the assembly method.

Speakers Selection Notes

Select this component when a round, low-cost miniature speaker is required for general voice or tone reproduction. The 50 Ohm impedance suits specific amplifier outputs or voltage-driven applications. Consider the 76 dBA efficiency for volume requirements in enclosed spaces. Compare against other Visaton series like K 14.25 if size constraints differ significantly.

Speakers Part Context

This part belongs to the Visaton K series of miniature speakers. These components are designed for cost-effective audio solutions in consumer electronics. The K 28 WP variant specifically offers a wider diameter than smaller counterparts, providing better bass response relative to its size while maintaining a thin profile.

Speakers Replacement Considerations

Direct substitutes may include other Visaton models with similar 50 Ohm impedance and round geometry, such as the K 28 WP - 8 OHM if impedance tolerance allows. Cross-brand replacements require matching the 28mm diameter, 5.5mm depth, and 1W power handling capabilities.
