6 / 28 page  Temperature Compensating Type High Dielectric Type 21 Capacitance Capacitance Within the specified tolerance. R7 : Within ±15% The capacitance change should be measured after 5 min. at Temperature Change (Table A) (-55℃ to +125℃) each specified temperature stage. Characteristics L8 : Within ±15% (1)Temperature Compensating Type (-55℃ to +125℃) The temperature coefficient is determind using the capacitance Within +15/-40% measured in step 3 as a reference. When cycling the temperature (+125℃ to +150℃) sequentially from step1 through 5 ( Δ C: +25℃ to +125℃, R9 : Within ±15% 5G:+25℃ to +150℃ other temp. coeffs.:+25℃ to +85℃) the (-55℃ to +150℃) capacitance should be within the specified tolerance for the temperature coefficient and capacitance change as Table A-1. The capacitance drift is caluculated by dividing the differences betweeen the maximum and minimum measured values in the step Temperature Within the specified tolerance. 1,3 and 5 by the cap value in step 3. Coefficent (Table A) Capacitance Within ±0.2% or ±0.05 pF Drift (Whichever is larger.) (2) High Dielectric Constant Type The ranges of capacitance change compared with the above 25℃ value over the temperature ranges shown in the table should be within the specified ranges. Initial measurement for high dielectric constant type. Perform a heat treatment at 150+0/-10℃ for one hour and then set for 24±2 hours at room temperature. Perform the initial measurement. ■AEC-Q200 Murata Standard Specification and Test Methods No AEC-Q200 Test Item AEC-Q200 Test Method Specification.
