Questions answered in these manuals
How should insulation resistance be measured?
Measure insulation resistance with a DC voltage that does not exceed the rated voltage, at 20 °C/25 °C and 75 % RH, within two minutes of charging.
From: MURATA Monolithic Ceramic Capacitors GR_R6/R7/F5/E4 (X5R/X7R/Y5V/Z5U)
What voltage is applied for high‑dielectric‑constant type testing?
Apply 250 % of the rated voltage for 1 to 5 seconds while keeping the charge/discharge current below 50 mA.

What is the operating temperature range for the R7 series capacitors?
The R7 series operates from –55 °C to +125 °C.
What voltage test is required for temperature‑compensating type capacitors?
No failure should be observed when 300 % of the rated voltage is applied.
