SERIESPPC,NPC RESISTORS,TERMINATIONS HighPowerChip–50&100Ohms GENERALINFORMATION 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 peak and average RF power capability. ORDERINGINFORMATION EXAMPLE: Typical Model No. PPC or NPC T 25-50 X 50R0 (See Note A Below) or 1000 J Physical Dimensions Prefix Tinning (see Note 4) H = Sn96 T = Sn63 Size TO P VIEW Tolerance Key W F = 1% G = 2% J = 5% (Standard) Terminal type (X, W or G) Ohmic Value (Note A) B B NOTE A Resistance value is expressed using military 4-digit call-out. 50R0 = 50 Ohms 1000 = 100 Ohms TYPE X Other values from 10–500 Ohms may be available as special order. Contact factory for availability. L GENERAL SPECIFICATIONS Solderable Terminals 50 Ohms or 100 Ohms T B B Electroplated Silver over Nickel (PPC) Gold over Nickel alloy (NPC) Substrate Beryllium Oxide Ceramic Resistive Element Thin Film and Thick Film* TYPE G T 50 Ohms ONLY L NOTES 0.005[0.13] MAX 1. The “L” and “T” dimensions are for the substrate only and do not include terminal thickness or optional tinning thickness. B B 2. Thermal Resistance (R°) is measured in °C/W between resistive film and mounting surface. 3. The CW power rating is based on maximum film temperature of +150°C and with maximum heatsink temperature of +100°C. Power is based on infinite and ideal heatsink. Type “W” termination style does not have full back plane metallization and typically handles 1/10 the rated power. TYPE W (Note 3) 50 Ohms or 100 Ohms T L 4. Tinning with Sn96 “Lead Free” high temperature solder will maintain RoHS. PERFORMANCE SPECIFICATIONS W Model Prefix L (Note 1) in [mm] T (Note 1) in [mm] B RØ° C/W Max. (Note 2) C/W Power Freq.
