The resistive layer is laser-trimmed to achieve the precise 49.9Ohm resistance with \u00b11% tolerance. The Ni-barrier termination with Sn plating provides reliable solder wetting and prevents silver migration. The compact 0402 (1005 Metric) package minimizes parasitic inductance and capacitance, making it suitable for both DC and high-frequency signal applications.","pin_description":"\n
