The resistors are also suitable for circuits exposed to high levels of electromagnetic interference or electrostatic discharge. The applications are in all fields of automotive, telecommunication, industrial and medical equipment. • • • • Automotive Telecommunication Industrial Medical equipment METRIC SIZES DIN: 0204 CECC: RC 3715M TECHNICAL SPECIFICATIONS DESCRIPTION CMA 0204 Metric CECC size RC 3715M Resistance range 10 Ω to 100 kΩ Resistance tolerance ±2% Temperature coefficient see T.C. graph Operation mode Climatic category (LCT/UCT/days) Rated dissipation, P70 (1) standard power 55/125/56 55/155/56 0.25 W 0.4 W Operating voltage, Umax AC/DC 200 V Film temperature 125 °C 155 °C Max. resistance change at P70 10 Ω to 100 kΩ for resistance range, ∆R/R max., after: 1000 h ±1% ±2% 8000 h ±2% ±4% Specified lifetime 8 000 h Permissible voltage against ambient (insulation): 1 minute; Uins 300 V continuous 75 V ≤ 1 × 10-9/h Failure rate Note 1. The power dissipation on the resistor generates a temperature rise against the local ambient, depending on the heatflow support of the printed-circuit board (thermal resistance). The rated dissipation applies only if the permitted film temperature is not exceeded. Furthermore, a high level of ambient temperature or of power dissipation may raise the temperature of the solder joint, hence special solder alloys or board materials may be required to maintain the reliability of the assembly.

A homogeneous and dense carbon film is enviromental text procedures of the IEC 60068 series. deposited on a high grade ceramic body (85 % Al2O3). Nickel plated steel termination caps are firmly pressed on Vishay BEYSCHLAG has achieved "Approval of the coated rods. A special laser is used to achieve the target Manufacturer" in accordance with EN 100 114-1. The value by smoothly cutting a helical groove in the resistive release certificate for “Technology Approval Schedule” in layer without damaging the ceramics. The resistors are accordance with CECC 240001 based on EN 100114-6 is covered by protective coating designed for electrical, granted for the Vishay BEYSCHLAG manufacturing mechanical and climatic protection.The terminations receive process. a final pure tin on nickel plating. Four colour code rings designate the resistance value and tolerance in accordance with IEC 60 062. The result of the determined production is verified by an extensive testing procedure performed on 100 % of the individual resistors. Only accepted products are laid directly into the blister tape in accordance with IEC 60 286-3. ASSEMBLY The resistors are suitable for processing on automatic SMD assembly systems. They are suitable for automatic soldering using wave, reflow or vapour phase. Excellent solderability is proven, even after extended storage in excess of 10 years. The encapsulation is resistant to all cleaning solvents commonly used in the electronics industry, including alcohols, esters and aqueous solutions. The resistors are completely lead (Pb)-free, the pure tin plating provides compatibility with lead (Pb)-free soldering processes. The immunity of the plating against tin whisker growth has been proven under extensive testing. All products comply with the CEFIC-EECA-EICTA list of legal restrictions on hazardous substances. This includes full compatibility with European RoHS directive.
