KNP3WS 1K 5% Resistor - The Standard for 1,000Ohm 3W Carbon Film Needs

The KNP3WS 1K 5% resistor is a widely used 1,000 ohm, 3 watt carbon film resistor with a 5% tolerance, perfect for demanding applications in electronics prototyping, repair, and small production runs. Its flame-retardant coating, robust 3W power handling, and industry-standard axial leads make it a reliable choice for engineers, students, and procurement teams who need consistent performance to SANS-aligned parameters.

Why Choose KNP3WS 1K 5%?

  • Fits breadboards, stripboards, and PCB designs with standard 0.6-0.7mm leads.
  • Low noise, high stability carbon film element - ideal for signal, load, or pull-down use.
  • Popular in STEM kits, power supply builds, and audio/LED projects across South Africa.
Local Stock Note: Communica keeps large volumes of KNP and CFR series carbon film resistors, including the 1K 3W value, ready for walk-in collection or next-day express shipping.

Technical Specs - KNP3WS 1K 5% Resistor

Parameter Value
Resistance (Ohm) 1,000 (1K)
Tolerance 5%
Power Rating 3W @ 70 degreesC
Body Style Axial carbon film

This value and form factor is compatible with standard through-hole assembly, and can be swapped in place of similar 1K 3W resistors for most educational, industrial, and hobby applications. Tolerance color code (Brown-Black-Red-Gold) ensures easy identification during assembly.

Compatibility & Project Uses

  • Current limiting for LEDs and power rails
  • Load banks for test benches
  • Voltage divider networks in analog circuits
  • General-purpose drop-in replacement for 1K 3W resistors in amplifiers, motor drivers, and chargers
Need a full range? Get adjacent values (100Ohm-22KOhm), E12/E24 ranges, and both 2W/3W options from the carbon film and metal film resistor listings.
