LSR37 Vishay BCcomponents High Voltage Surge Metal Glaze Leaded Resistor FEATURES • High pulse-loading (10 kV as specified) capability (flashes) • Good replacement for carbon-composite resistors • Lead (Pb)-free solder contacts • Pure Tin plating provides compatibility with lead (Pb)-free and lead containing soldering processes A metal glazed film is deposited on a high grade ceramic body. After that caps are applied to the rods and tinned electrolytic copper wires are welded to these end caps. The resistors are coated with a light-blue lacquer which provides electrical, mechanical and climatic protection. The encapsulation is resistant to all cleaning solvents according to IEC 60068-2-45. • Compliant to RoHS directive 2002/95/EC APPLICATIONS • Application in overload and high voltage pulse hazard circuits (TV-sets, monitors), high power electronic ballasts TECHNICAL SPECIFICATIONS DESCRIPTION VALUE 220 Ω to 910 Ω Resistance Range (1) Resistance Tolerance and Series 1 kΩ to 10 kΩ ± 10 %; ± 20 %; E12 series Rated Dissipation, P70 0.5 W Thermal Resistance, Rth 120 K/W Temperature Coefficient Voltage Coefficient Maximum Permissible Voltage Umax. 0 ppm/K to + 600 ppm/K - 600 ppm/K to + 200 ppm/K 0 to + 350 ppm/V ± 50 ppm/V Pn x R V= Dielectric Withstanding Voltage of the Insulation for 1 Min Basic Specifications 700 V IEC 60115-1 Climatic Category (IEC 60068-1) 55/155/56 Stability After: Load (1000 h, P70) ΔR max.: ± (3.0 % R + 0.10 Ω) Long Term Damp Heat Test (56 Days) ΔR max.: ± (3.0 % R + 0.10 Ω) Soldering (10 s, 260 °C) ΔR max.: ± (1.0 % R + 0.10 Ω) High Voltage Test for R-Value > 3.3 kΩ, 10 kV; 1 nF; 50 x 12/Min ΔR/R max.: ± 20 % (typical value ± 10 %) ESD Contact Discharge 12 kV; 100 Pulses ΔR/R max.: ± 20 % (typical value: ± 10 %) Note (1) R values below 220 Ω are available on request www.vishay.com 190 For technical questions, contact: filmresistorsleaded@vishay.com Document Number: 28735 Revision: 19-Oct-09 LSR37 High Voltage Surge Metal Glaze Leaded Resistor Vishay BCcomponents PART NUMBER PART NUMBER: LSR3700001002KA100 L S R 3 7 0 0 0 0 1 0 0 2 K A 1 0 0 MODEL/SIZE VARIANT TCR/MATERIAL VALUE TOLERANCE PACKAGING (1) SPECIAL LSR3700 0 = Neutral 0 = Standard 3 digit value 1 digit multiplier MULTIPLIER 9 = *10-1 0 = *100 1 = *101 2 = *102 K = ± 10 % M = ± 20 % A1 R5 The 2 digits are used for all special parts.

Three bands are used for 20 % tolerance with no indication for the tolerance. Four bands are used for 10 % tolerance. Grey is used instead of silver for 10 % because metal particles in the lacquer could affect high-voltage properties. OUTLINES The length of the body (L1) is measured by inserting the leads into holes of two identical gauge plates and moving these plates parallel to each other until the resistor body is clamped without deformation (IEC 60294). FUNCTIONAL PERFORMANCE PRODUCT CHARACTERIZATION Standard values of rated resistance (nominal resistance) are taken from the E12 series with a tolerance of 10 % or 20 %. The values of the E12 series are in accordance with IEC 60063. The limiting voltage DC is not applicable, because the maximum rated voltage for the maximum Rn-value of 10 kΩ at Pn = 0.5 W is only 70.7 V.
