300/600pcs Metal Film Resistor Assortment Kit – 30 Values, 1% Tolerance, 1/4W

Whether you're a hobbyist, student, or professional electronics engineer, this metal film resistor assortment kit is your all-in-one solution for breadboarding, PCB prototyping, circuit repairs, and DIY electronics projects. With 30 different resistance values ranging from 10Ω to 1MΩ, you'll always have the right resistor on hand — no more last-minute parts runs or project delays.

Available in a 300-piece (10 of each value) or a 600-piece (20 of each value) pack, and your choice of a neatly organized box or a convenient bag. Made in Mainland China.

Why Choose This Resistor Kit?

• 1% Precision Tolerance: Metal film construction delivers tight ±1% accuracy, far superior to standard carbon film resistors — ideal for sensitive analog circuits, measurement applications, and anywhere accuracy counts.
• High Stability: Consistent performance across a wide range of operating conditions. These resistors won't drift or fluctuate, giving you reliable, repeatable results every time.
• Low Temperature Coefficient: Minimal resistance variation with temperature changes means your circuits stay accurate whether your workspace is cool or warm.
• Low Noise Design: Metal film technology inherently produces less electrical noise than carbon composition alternatives — perfect for audio circuits, amplifiers, and precision instruments.
• Automatic Insertion Compatible: Standard axial lead format supports automated PCB insertion processes, saving time during production or assembly runs.
• Comprehensive Range: 30 carefully selected resistance values from 10R to 1MΩ cover the vast majority of everyday electronics needs in a single kit.

Frequently Asked Questions

Q: What resistance values are included in this metal film resistor assortment kit?

A: The kit includes 30 different resistance values spanning from 10 Ohms (10R) all the way up to 1 Megaohm (1MΩ). This wide range covers the most commonly needed values for hobbyist and professional electronics projects, including prototyping, circuit design, and repairs.

Q: What is the difference between the 300pcs and 600pcs options?

A: Both options include the same 30 resistance values. The 300pcs pack gives you 10 resistors of each value, while the 600pcs pack gives you 20 of each value. The 600pcs kit is ideal if you work on high-volume projects or want a larger backup stock. The 600pcs option is available either in a sorted box or a bag.

Q: Why are metal film resistors better than carbon film resistors?

A: Metal film resistors offer tighter tolerance (1% vs. 5% for most carbon film types), lower noise, and a lower temperature coefficient. This makes them significantly more accurate and stable — especially important in precision analog circuits, audio equipment, measurement instruments, and any application where consistent performance is critical.

Q: Are these resistors compatible with standard breadboards and PCBs?

A: Yes. These are standard axial-lead through-hole resistors with 1/4W power rating, fully compatible with breadboards, perfboards, and PCB through-hole pads. They also support automated PCB insertion processes.

Q: Can beginners use this resistor kit?

A: Absolutely. This assortment kit is perfect for beginners learning electronics, students in lab classes, and seasoned makers alike. Having 30 different values readily available removes guesswork and speeds up any project from start to finish.
