WR02X4871FAL

Component

4.87 kΩ±1%50 mW02010603 metricthick filmlead-free

WR02X4871FAL is a compact 4.87 kΩ ±1% 0201 thick-film resistor rated at 50 mW at 70°C for general-purpose, high-density surface-mount designs.

Best for

  • Space-constrained general-purpose resistor networks
  • High-density PCB assemblies
  • Low-power consumer electronics

Avoid if

  • Required dissipation exceeds 50 mW at 70°C
  • Operating temperature exceeds +125°C
  • A larger package is needed for assembly robustness or power margin

Check before use

  • Apply derating above 70°C
  • Verify continuous voltage against the 25 V maximum and power-based RCWV
  • Confirm 0201 placement and soldering capability
  • Confirm lifecycle and current distributor availability separately
