5 / 13 page No. Item Specifications Test Method Temperature Compensating Type No removal of the terminations or other defect should occur Fig. 1a Adhesive Strength of Termination 10 Solder the capacitor to the test jig (glass epoxy board) shown in Fig. 1a using an eutectic solder. Then apply 10N* force in parallel with the test jig for 10 T1 sec. The soldering should be done either with an iron or using the reflow method and should be conducted with care so that the soldering is uniform and free of defects such as heat shock. *2N (GRp03), 5N (GRp15, GRM18) High Dielectric Type c Baked electrode or copper foil Solder resist (in mm) Type a b c GRp03 GRp15 GRM18 GRM21 GRM31 GRM32 GRM43 GRM55 0.3 0.4 1.0 1.2 2.2 2.2 3.5 4.5 0.9 1.5 3.0 4.0 5.0 5.0 7.0 8.0 0.3 0.5 1.2 1.65 2.0 2.9 3.7 5.6 Continued from the preceding page. Continued on the following page. Within the specified tolerance (Table A-1) Capacitance Temperature Characteristics 9 (2) High Dielectric Constant Type The ranges of capacitance change compared with the 20 D value over the temperature ranges shown in the table should be within the specified ranges. * In case of applying voltage, the capacitance change should be measured after 1 more min. with applying voltage in equilibration of each temp. stage. The capacitance change should be measured after 5min. at each specified temp. stage. (1)Temperature Compensating Type The temperature coefficient is determind using the capacitance measured in step 3 as a reference. When cycling the temperature sequentially from step 1 through 5 (5C : W25D to W125D/∆C : W20D to W125D : other temp. coeffs. : W25D to W85D/W20D to W85D) the 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 between the maximum and minimum measured values in the step 1, 3 and 5 by the cap. value in step 3.
