FEATURES QUICK REFERENCE DATA DESCRIPTION Resistance range Resistance tolerance and series Maximum dissipation at Tamb = 70 °C Thermal resistance, Rth Temperature coefficient Voltage coefficient Maximum permissible voltage Dielectric withstanding voltage of the insulation for 1 minute Basic specifications Climatic category (IEC 60068) Stability after: load (1000 hours) climatic test soldering High voltage test for R-value > 3.3 kΩ, 10 k V; 1 n F; 50 × 12/minutes ESD contact discharge 12 k V; 100 pulses Table 1 ORDERING INFORMATION Ordering code (12NC) TYPE IEC 60115-1B 55/155/56 VALUE - High pulse-loading capability (flashes) - Good replacement for carbon-posite resistors. APPLICATIONS 1 kΩ to 10 kΩ 220 Ω to 910 Ω ±10%; ±20%; E12 series 0.5 W 120 K/W 0 to +600 × 10- 6/K - 600 to +200 × 10- 6/K 0 to +350 × 10- 6/K - Application for overload and high voltage pulse hazard circuits (TV-sets, monitors). DESCRIPTION A metal glazed film is deposited on a high grade ceramic body. After that caps are applied to the rods and 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 “MIL-STD 202E, method 215” and “IEC 60068-2-45”. ±50 × 10- 6/V Pn × R V = 700 V ∆R/R max.: ±3% + 0.1 Ω ∆R/R max.: ±3% + 0.1 Ω ∆R/R max.: ±1% + 0.1 Ω ∆R/R max.: ±20% (typical value ±10%) ∆R/R max.: ±20% (typical value: ±10%) Ordering code as function of tolerance and packaging TOLERANCE (%) ORDERING CODE 2322 245 1000 units IN AMMOPACK 12... 11... ORDERING EXAMPLE The ordering code for a LSR37, resistor value 1.5 k W, 10% tolerance, supplied on a bandolier of 1000 units in ammopack, is: 2322 245 12152. 5000 units ON REEL 22... 21... - The resistors have a 12-digit ordering code staring with 2322 245 - The subsequent 2 digits indicate the resistor type and packaging; see Table 1. - The remaining digits...
