30-Value Metal Film Resistor Kit

The JacobsParts RESISTORS-A kit supplies 600 axial-lead metal film resistors across 30 standard values from 10 ohm to 1M ohm. Each value is represented by 20 pieces, giving hobbyists, students and repair technicians a broad selection for breadboarding, prototyping and through-hole repairs. The 1/4W rating and 1% tolerance suit general-purpose analogue and digital circuits. Packaged in a single assortment, it reduces the need to order individual values for common projects.

1/4W 1% Capacity and Headroom

The 0.25W dissipation limit comfortably handles typical low-power signal, pull-up, biasing and LED current-limiting tasks in 5V and 3.3V logic circuits. Metal film construction provides low noise and stable temperature coefficient for precision divider networks and sensor interfaces. The kit runs out when designs demand higher power dissipation, tighter tolerance than 1%, surface-mount footprints or resistance values outside the 10 ohm to 1M ohm range. High-voltage or pulse-withstanding applications also exceed the axial lead rating.

Upgrade from Loose or Salvaged Parts

Builders moving from salvaged carbon-composition resistors or mismatched loose assortments gain consistent 1% tolerance, labelled packaging and a complete decade coverage in one box. The jump is worth it when prototype iterations require repeatable values, when Bill-of-Materials calls for standard E24 series values, or when teaching labs need identifiable, traceable components. It does not replace the need for higher wattage, precision 0.1% or SMD resistor stocks for advanced production runs.

Questions about this item

Will the 1/4W 1% metal film resistors from this kit work alongside older carbon-composition parts in the same circuit?

Yes, the 1% tolerance and metal film construction give tighter, more stable values than typical older carbon-composition resistors, so they can replace or supplement them without changing the circuit design.

How can I confirm the kit delivers the stated 1% tolerance across the 30 values after opening it?

Measure a sample from each of the 30 value bands with a multimeter; each reading should fall within 1% of the marked resistance, confirming the 600-piece assortment meets specification.

What exactly is included in the box and do I need to buy anything else to start using the resistors?

The box contains 600 axial-lead metal film resistors — 20 pieces of each of the 30 values from 10 ohm to 1M ohm — ready to use; no extra components are required for through-hole soldering.
