Notes:

1. Certified with each stage.

2. Application dependent. Requires the selection of an appropriate amplifier with sufficient voltage and current.

3. Application dependent. Dry environments between 0° and 70° C up to 10,000 hours.

4. Long-term exposure to temperature cycles and wet environments will require periodic maintenance.
