Selection Notes
- Capacitance falls with applied DC bias in high-K dielectrics (X5R, X7R, Y5V). The nameplate value is measured at 0 V — check the DC bias curve for the voltage the part actually sees.
- Class 1 dielectrics (C0G/NP0) hold capacitance across voltage and temperature but top out in the nanofarad range. Class 2 gives far more capacitance per volume at the cost of stability.
- Self-heating from ripple current adds to ambient. Keep the part below its rated temperature with margin, especially in high-frequency switching nodes.
- Flex cracks come from board bending, not electrical stress. Where the board is depanelised or screwed down near the capacitor, use a soft-termination variant.
Common Questions
How many part numbers are in the GRM31B5 series?
24. The table above lists every one, sorted by part number.
What do the parts in the GRM31B5 series have in common?
They share the same multilayer ceramic capacitor construction and case-size family; the differences are the electrical values shown per row.
Where can I find the full specification for a GRM31B5 part?
Each part number links to Murata's official product page, which carries the detailed specification sheet, reliability data and simulation models.
