Introduction

FFH-26867-I05 is a ferrofluid, Type III damped, externally vented FH-26555 receiver with a 5dB peak relative to 1kHz sensitivity under constant voltage drive conditions.

Features

• The device will produce the following sound pressure levels under the test conditions described in Table 3. Nominal sensitivity at 1kHz is dB relative to 20μPa. All other values are in dB relative to sensitivity at 1kHz.
• Pressure Relief: When a pressure of 15 inches of water (3736Pa) is applied to the port aperture, airflow through the pressure relief vent is 1.0 to 2.5cc/min.
• Temperature: Operating range 0°C to 63°C (sensitivity variation within ±3dB over this range). Sensitivity at 0°C is 2dB lower than at room temperature. Storage range: -40°C to 63°C.
