CRCW12180000Z0EK

The production process is strictly controlled and follows an extensive set of instructions to ensure repeatability. Cermet film layers and glass covercoats are deposited on advanced (Al₂O₃) ceramic substrates with prefabricated internal contacts. A special laser is used for fine trimming of the resistive layer to achieve the target value without damaging the ceramic. The resistive element is covered by a protective coating for electrical, mechanical, and climatic protection. Terminals receive a final pure matte nickel-tin plating finish. Following the defined production process, 100% of individual chip resistors undergo an extensive test program to verify results. Only products that pass the tests are loaded directly into tape and reel in accordance with IEC 60286-3 Type 1a and Type 2a. These resistors are suitable for automatic SMD assembly systems. They are compatible with automatic soldering using wave soldering, reflow soldering, or vapor phase soldering, as specified in IEC 61760-1. The packaging materials are resistant to all cleaning solvents commonly used in the electronics industry, including alcohols, esters, and aqueous solutions. When conformal coatings, encapsulants, and their associated processes are used, qualification by appropriate methods is recommended to ensure long-term stability of the entire system. These resistors are RoHS compliant, and the pure matte tin plating process makes them compatible with both lead-free (Pb-free) and leaded soldering processes. Solderability is guaranteed within 2 years of production or requalification. The maximum storage period is 20 years. Extensive testing has demonstrated the plating's resistance to tin whisker growth.
