• Capacitors should be as physically close to the chip as possible. Keep the total trace
• Use only SMT capacitors where possible. A capacitor size of 0805 achieves the
• For capacitors on signal traces; connect capacitors directly to pin, not splitting the
length less than 0.3 in. It is better to have short trace to a ground or power via
than a longer trace going to a ground or power pin since the inductance of the
planes is relatively lower. Trace inductance (~8 nH per in) is a large part of the total
effective capacitor inductance.

large values (> 1 µF). Avoid 0603 capacitors since they show higher failure rates.

— Use 470-pF or 1,000-pF SMT ceramic capacitors for decoupling all connector
— Use 0.1-µF SMT ceramic capacitors for general IC decoupling and ESD
— If two different values of small capacitors are needed, separate the values by at
— Bulk capacitors should be at least 10 times the value of the largest decoupling
— Use 22-µF or 47-µF electrolytic SMT capacitors for general bulk decoupling
— Use 100-µF tantalum SMT capacitors for voltages with large current steps, like
pins for EMI control.

superior temperature and aging characteristics. Use Z5U or Y5V dielectric only
