details. GC GC Style “GC” denotes GLASS ENCAPSULATED CHIP structure Nominal Diameter in mils: 14= 0.014” nom, 0.016” max; 16 = 0.016” nom, Lead configuration code letter “K” = adjacent cut leads “P” = opposite cut leads Material System Code Letter (see table on page2) Zero-power resistance as 25°C (see NOTE 2) Tolerance Code Letter (See Note 1 and Standard Tolerances) K F 104 K Coding NOTE 1: Special tolerances are available on request. Consult factory for special resistance tolerances, non- standard resistances and/or non-standard temperatures. NOTE 2: The zero-power resistance at 25°C, expressed in ohms, is identified by a three-digit code number. The first two digits represent significant figures, and the last digit specifies the number of zeros to follow. Example: 51 kOhms = “513”. The standard resistance values are from the 24-value series decade as specified in Military Standard MS90178. AAS-920-584A-03/2014 www.amphenol-sensors.com © 2014 Amphenol Corporation.
