Plastic compartment box holding 150 assorted IC chips

Ruth's sister

Ruth's sister IC Chip Assortment 150 Pcs

SKU CH-QKVB-EKWJR

Contains 150 assorted IC chips including op-amps, oscillators, PWM controllers and popular types such as PC817, NE555, LM358, LM324, JRC4558, LM393, LM339, NE5532, LM386 and TDA2030

  • 150-piece kit covers op-amps, oscillators and PWM controllers for diverse circuits
  • Includes NE555 timer, LM358 dual op-amp and LM324 quad op-amp for signal conditioning
  • PC817 optocoupler, LM393 comparator and LM339 quad comparator enable isolation and threshold detection
  • NE5532 audio op-amp, LM386 amplifier and TDA2030 power amp support sound projects

IC Chip Assortment for Prototyping

This 150-piece kit bundles common op-amps, oscillators, PWM controllers, optocouplers and audio amplifiers for breadboard experiments and repair work. Students, hobbyists and technicians receive multiple copies of NE555, LM358, LM324, PC817, LM393, LM339, NE5532, LM386, TDA2030 and JRC4558 in a single package. The selection covers timing, signal conditioning, isolation and low-power audio tasks without needing separate orders. Builders who need surface-mount variants or higher-voltage parts must source them elsewhere.

Passive Components Draw No Active Power

Each device operates only when inserted into a powered circuit, so the kit itself adds no thermal load, fan noise or standby consumption. Total dissipation depends entirely on the surrounding design and supply rails chosen by the user. Individual datasheets specify maximum junction temperatures and quiescent currents for each part number. Installers must calculate heatsinking and supply budgets per application rather than relying on kit-level ratings.

Questions about this item

How do I install the NE555 timer IC from the 150-piece assortment onto a breadboard, and what orientation mistake should I avoid?

Align the notch or dot on the NE555 with pin 1 at the top-left, then press the DIP pins firmly into the breadboard rows; the step people get wrong is inserting it backwards, which reverses power and ground connections.

Which ICs in the 150-piece kit are most likely to need replacement after extended prototyping use?

The NE555 timer, LM358 dual op-amp, and LM386 audio amplifier see the highest switching and thermal stress in breadboard circuits, so they tend to fail first and should be kept as spares.
