Who Is This For?

Whether you're a hobbyist, electronics engineer, PCB designer, or repair technician, this bulk assortment ensures you'll always have the right capacitor value on hand. COG/NPO capacitors are the go-to choice wherever predictable, drift-free performance matters — from antenna-tuning networks and filter circuits to precision timing and signal-processing applications.

Why COG/NPO?

COG (also designated NPO) is the most stable ceramic capacitor dielectric class. Its capacitance changes negligibly with temperature, voltage, and frequency — ideal for designs that demand rock-solid electrical characteristics under varying operating conditions.

Frequently Asked Questions

Q: What capacitance values are included in this 4000-piece 0603 SMD capacitor assortment?

A: The assortment includes eight precision values: 8.2pF, 9pF, 9.1pF, 10pF, 11pF, 12pF, 13pF, and 15pF. The 4000 pieces are distributed across these values, giving you a well-stocked supply of small-value, high-frequency capacitors.

Q: What does COG/NPO mean and why does it matter?

A: COG and NPO are equivalent designations for the most stable class of ceramic capacitor dielectric. They exhibit near-zero capacitance drift over temperature, voltage, and time — making them the preferred choice for RF, timing, filter, and oscillator circuits where accuracy and stability are critical.

Q: Are these capacitors RoHS compliant?

A: Yes. All capacitors in this assortment are fully RoHS certified and contain no high-concern chemicals, making them suitable for use in products destined for the EU and other markets with strict environmental compliance requirements.

Q: What is the voltage rating of these SMD capacitors?

A: These capacitors are rated at 50V DC, which falls within the EU LVD low-voltage classification (below 50Vac or 75Vdc). They are well-suited for the vast majority of low-voltage electronic circuits and PCB applications.
