All rights reserved. 2009.01 - Rev.E L.C ∆C / C Item Performance Test conditions (based on JIS C 5101 −1 and JIS C 5101−3) +− After applying the rated voltage for 1000+72 h without discontinuation via the serial resistance of 3 Ω or less at a temperature of 85 2 C, leave the sample at room temperature / humidity for over 24h and measure the value. There should be nonsignificant abnormality. Appearance Loading at High temperature Less than 200% of initial limit +− Within 20% of initial value 150% of initial limit less than Appearance Terminal strength Capacitance The measured value should be stable. There should nonsignificant abnormality. A force is applied to the terminal until it bends to 1mm and by a perscribed tool maintain the condition for5s.(See the figure below) 1mm F (Apply force) (Unit : mm) 20 50 R230 45 45 thickness=1.6mm Apply force a circuit board product Adhesiveness The terminal should not come off. Apply force of 5N in the two directions shown in the figure below for 10 1s after mounting the terminal on a circuit board. +− Vibration Dimensions Resistance to solvents Solderability 3/4 or more surface area of the solder coated terminal dipped in the soldering bath should be covered with the new solder. Refer to "External dimensions" The indication should be clear Measure using a caliper of JISB 7507 Class 2 or higher grade. Dip in the isopropyl alcohol for 30 5s, at room temperature. +− Dip speed=25 2.5mm / s Pre −treatment(accelerated aging): Leave the sample on the boiling distilled water for 1 h. Solder temp. +− . : 245 5 C : 3 0.5s : M705 : Rosin25% IPA75% +− +− Duration Solder Flux Frequency : 10 to 55 to 10Hz/min. Amplitude : 1.5mm Time : 2h each in X and Y directions Mounting : The terminal is soldered on a print circuit board. Capacitance Measure value should not fluctuate during the measurement. Appearance There should no significant abnormality. Df (tan δ) |
