SERIES KAC Surface Mount Terminations (SMT) High Power, Aluminum Nitride (AlN), 10 - 150 Watts GENERAL INFORMATION Aeroflex / Inmet’s series of High Power Surface Mount Terminations are ideal for high frequency applications where small size and low costs are an important design criteria. The ability of these chips to be directly mounted to the PC Board eliminates the need for expensive mounting flanges and input tabs. Large solderable surface areas on the bottom of the chips allows for higher power dissipation in smaller sizes. All KAC series chips are manufactured using environmentally friendly Aluminum Nitride ceramic and are classified as RoHS compliant. ORDERING INFORMATION EXAMPLE: Typical Model No. KAC NPC T 100-200A X Z 50R0 G Prefix Tinning (Optional) H = Sn96 T = Sn63 PHYSICAL DIMENSIONS Size Terminal type Ohmic Value Tolerance, G = 2% (Standard) NOTE Tinning with Sn96 “Lead Free” high temperature solder will maintain RoHS compliance.
