Application Notes
For standard commercial applications.
† Contact factory for air flow rate details.
‡ 5-1000 Hz, PSD 0.002 g2/Hz; 1000-2000 Hz, PSD decreasing at 6 dB/octave.
For applications requiring an extended thermal range as well as increased shock and vibration requirements. Note: Level 3 ruggedization requires special consideration at the system level. Contact X-ES to discuss specific environmental requirements for rugged air-cooled products.
