Zero-TCR Ultra-Precision Resistor (Hermetically Sealed) TCR, Resistance Range, Tolerance, Rated Power HK HL Type TCR Resistance Range () HK HL Char. S 100 to 100k Rated Power (W) Resistance at 70C Tolerance (%)* 0.005 (V) 0.01 (T) 0.02 (Q) 0.3 0.05 (A) 0.1 (B) 0.5 (D) 1 (F) Symbols parenthesized are for type number composition. *Resistance figures are obtained by measuring the leads at point 12.73.2mm away from the root. Temperature Characteristics of Resistance Composition of Type Number R/R Example: (ppm) +100 HK S 10K000 T +50 +50 +40 Tolerance Resistance Value TCR Type Resistance value, in ohm, is expressed by a series of six characters, five of which represent significant digits. The sixth R or K is a dual- purpose letter that designates both the value range (R for ohmic; K for kilo-ohm) and the location of decimal point. 0 -50 -40 +15 +15 -15 -15 -50 -100 -55 0 +25 +50 +125 (C) Temperature Configuration Temperature (C) R/R (ppm) -55 0 040 015 015 050 HK, HL L +50 T +125 Reference Temperature +25C Type W L W T d F d HK HL 10.70.3 10.70.3 4.30.3 3.810.25 5.080.25 3010 0.650.05 Dimensions in mm (%) 100 egatnecreP rewoP detaR F Power Derating Curve 80 60 40 20 70 25 30 50 75 100 125 Ambient Temperature 150 (C) Performance Parameters Test Condition ALPHA Specification Maximum Rated Operating Temperature Working Temperature Range Maximum Working Voltage 25C, Rated Voltage, 96 hrs. -65C/30 min. +150C/30 min., 5 cycles Rated Voltage x 2.5, 5 sec.
