39 / 83 page C85E.pdf Jul.13,2011 The lead wire should be immersed into the melted solder of 350 ±10°C up to about 1.5 to 2mm from the main body for 3.5 ±0.5 sec. Pre-treatment: Capacitor should be stored at 125 ±3°C for 1 hr., then placed at room condition* for 24 ±2 hrs. before initial measurements. Post-treatment: Capacitor should be stored for 24 ±2 hrs. at room condition.* 12 Soldering Effect (Non-Preheat) Appearance No marked defect Capacitance Change Within ±10% Dielectric Strength (Between Lead Wires) Per item 4. Continued on the following page. *1 "Room condition" Temperature: 15 to 35 °C, Relative humidity: 45 to 75%, Atmospheric pressure: 86 to 106kPa T. C. -25 to +85 °C Temp. Char. Within ±15% Within ±20% +85 to +125 °C Within +15/-30% R C Step Temp. ( °C) 1 20 ±2 2 -25 ±3 3 20 ±2 4 125 ±2 5 20 ±2 The lead wire of a capacitor should be dipped into a ethanol solution of 25wt% rosin and then into molten solder for 2 ±0.5 sec. In both cases the depth of dipping is up to about 1.5 to 2mm from the root of lead wires. Temp. of solder: Lead Free Solder (Sn-3Ag-0.5Cu) 245 ±5°C H63 Eutectic Solder 235 ±5°C 11 Solderability of Leads Lead wire should be soldered with uniform coating on the axial direction over 3/4 of the circumferential direction. The capacitor should be firmly soldered to the supporting lead wire and vibrated at a frequency range of 10 to 55Hz, 1.5mm in total amplitude, with about a 1-minute rate of vibration change from 10Hz to 55Hz and back to 10Hz. Apply for a total of 6 hrs., 2 hrs. each in 3 mutually perpendicular directions. 10 Vibration Resistance Appearance No marked defect Capacitance Within specified tolerance D.F. Char. R: 0.2% max. Char. C: 0.3% max. As shown in the figure at right, fix the body of the capacitor and apply a tensile weight gradually to each lead wire in the radial direction of the capacitor up to 10N (5N for lead diameter 0.5mm), and keep it for 10 ±1 sec. 9 Strength of Lead Pull Lead wire should not be cut off. Capacitor should not be broken. Bending Each lead wire should be subjected to 5N (2.5N for lead diameter 0.5mm) of weight and bent 90 ° at the point of egress, in one direction, then returned to its original position and bent 90 ° in the opposite direction at the rate of one bend in 2 to 3 sec. The capacitance measurement should be made at each step specified in the Table. Pre-treatment: Capacitor should be stored at 125 ±3°C for 1 hr., then placed at room condition* for 24 ±2 hrs. before measurements. 8 Temperature Characteristics The dissipation factor should be measured at 20 °C with 1 ±0.2kHz and AC5V(r.m.s.) max. 7 Dissipation Factor (D.F.) Char. R: 0.2% max. Char. C: 0.3% max. The capacitance should be measured at 20 °C with 1±0.2kHz and AC5V(r.m.s.) max. 6 Capacitance Within specified tolerance The insulation resistance should be measured with DC500 ±50V within 60±5 sec. of charging. 5 Insulation Resistance (I.R.) Between Lead Wires 10000M Ω min. The capacitor should not be damaged when DC voltage of 200% of the rated voltage (DC1 to 3.15kV) or DC voltage of 250% of the rated voltage (DC500V) is applied between the lead wires for 1 to 5 sec. (Charge/Discharge current V50mA) 4 Dielectric Strength Between Lead Wires No failure Body Insulation No failure The capacitor is placed in the container with metal balls of diameter 1mm so that each lead wire, short circuited, is kept about 2mm off the metal balls as shown in the figure at right, and AC1250V(r.m.s.) <50/60Hz> is applied for 1 to 5 sec. between capacitor lead wires and metal balls. (Charge/Discharge current V50mA) The capacitor should be visually inspected. 3 Marking To be easily legible The capacitor should be visually inspected for evidence of defect. Dimensions should be measured with slide calipers. 2 Appearance and Dimensions No visible defect, and dimensions are within specified range. 1 Operating Temperature Range -25 to +125 °C No. Test Method Specifications Item DEH Series (125 °C Guaranteed / Low-dissipation Factor / DC250V-3.15kV) Specifications and Test Methods W About 2mm Metal balls DEH Series Specifications and Test Methods 37 7 !Note • Please read rating and !CAUTION (for storage, operating, rating, soldering, mounting and handling) in this catalog to prevent smoking and/or burning, etc. • This catalog has only typical specifications because there is no space for detailed specifications.
