Specifying Tip:
For best results when selecting a coaxial termination for a given connector style, make sure to consider the amount of power being absorbed and the acceptable level of reflection (VSWR) that can be tolerated over the operating frequency range.

Notes:
1. 50 ohms nominal impedance is standard
2. Operating temperature from -55° C to +85° C
3. Rated power is at 25° C ambient temperature through natural air convection and derates linearly to 0 watts @ +125° C
