11 / 13 page No. Item Specifications Test Method Temperature Compensating Type High Dielectric Type Temperature Cycle 15 Fix the capacitor to the supporting jig in the same manner and under the same conditions as (10). Perform the five cycles according to the four heat treatments listed in the following table. Let sit for 24 T2 hours (temperature compensating type) or 48 T4 hour (high dielectric constant type) at room temperature, then measure. #Initial measurement for high dielectric constant type Perform a heat treatment at 150 Y10 D for one hour and then let sit for 48 T4 hours at room temperature. Perform the initial measurement. No marking defects Within T2.5% or T0.25pF (Whichever is larger) R6, R7 : Within T7.5% E4, F5 : Within T20% Appearance The measured and observed characteristics should satisfy the specifications in the following table.

Immerse the capacitor in a eutectic solder solution at 270 T5D for 10 T0.5 seconds. Let sit at room temperature for 24T2 hours (temperature compensating type) or 48 T4 hours (high dielectric constant type), then measure. #Initial measurement for high dielectric constant type Perform a heat treatment at 150 Y10 D for one hour and then let sit for 48 T4 hours at room temperature. Perform the initial measurement. *Preheating for GRM32/43/55 R6, R7 : Within T7.5% E4, F5 : Within T20% [R6, R7] W.V. : 25Vmin. : 0.025max. W.V. : 16/10V : 0.035max. W.V. : 6.3V : 0.05max.
