Its small footprint makes it suitable for densely populated circuit boards, while its robust construction allows it to withstand mechanical and thermal stress.
Structure and Working Principle
The WR04X2613FTL resistor consists of a ceramic substrate coated with a resistive thick-film layer, which is then laser-trimmed to achieve the desired resistance value. The resistive layer is protected by a glass coating, ensuring long-term stability and protection against environmental factors. When current flows through the resistor, the resistive layer dissipates energy as heat, thereby limiting the current or dividing the voltage as required by the circuit. The precision of the resistor is determined by the quality of the thick-film material and the accuracy of the laser-trimming process.
