Table 28. Bulk Capacitance Requirements per Power Plane
NOTES:
1. Placement of the above capacitance requirements should be located near the connector.
2. V_CLK filtering should be located next to the system clock synthesizer.
3. RMS ripple current specification depends on V_DC input for the module. See Figure 8.
4. If Tantalum* capacitors are used, a 50% voltage derating practice must be observed. For example, a 5.0-V
rail requires a 10.0-V rated capacitor.
5. In order to reduce ESR, Intel recommends the use of multiple bulk capacitors rather than a single large
capacitor.
6. Intel strongly recommends that system designers pay close attention to capacitor design recommendations.
Specifically, the "Capacitance vs. Temperature De-rating Curve," "Capacitance vs. Applied DC Voltage De-
rating Curve," and the "Capacitance vs. Frequency De-rating Curve." Some capacitor dielectrics are
particularly susceptible to these conditions, for example Y5V ceramic capacitors.
7. Specifications labeled N/A are not available.
Figure 8 shows the dependence of V_DC ripple current on V_DC.
