SERIES ANC RESISTORS, TERMINATIONS High Power Chip, Aluminum Nitride – 50 & 100 Ohms GENERAL INFORMATION When mounted on an appropriate heat sink, these chip devices provide high power dissipation in terminations and as balancing resistors in Wilkinson power divider networks. Laser trimming provides maximum RF power capability. Aluminum nitride is used for those applications where the use and disposal of beryllium oxide is a concern. ORDERING INFORMATION EXAMPLE: Typical Model No. ANC NPC T 250-250 X 50R0 (See Note 1 Below) or 1000 J Prefix PHYSICAL DIMENSIONS Tinning (See Note 2) H = Sn96 T = Sn63 Tolerance Key F = 1% G = 2% J = 5% (Standard) Size Terminal type (X or G) B Ohmic Value (Note 1) B TYPE X (RESISTOR) NOTES 50 Ohms or 100 Ohms T 1. Resistance value is expressed using military 4-digit call-out. 50R0 = 50 Ohms 1000 = 100 Ohms L Other values from 10–500 Ohms may be available as special order. Contact factory for availability. 2. Tinning with Sn96 “Lead Free” high temperature solder will maintain RoHS compliance. 3. The “L” and “T” dimensions are for the bare substrate, and do not include terminal thickness or tinning thickness.
