NIOBIUM ELECTROLYTIC CAPACITORS NMCU Series Product specifications (Ultra Flat Low Profile Niobium Chip Capacitors) Features A niobium capasitor is a polar capaciror. Low profile niobium chip capacitors developed to meet growing needs for flat capacitors where height is critical. Small and low profile:Obtained by thinning the NMC type. Operating temperature range –55°C ~ +105°C Rated voltage DC2.5 ~ 10V 85°C Surge voltage DC3.0 ~ 12V 85°C Derated voltage DC1.7 ~ 6.7V 105°C Capacitance 4.7 ~ 47µF 120 Hz, 1.5V Capacitance tolerance ±20% Paragraph 4.7, 120 Hz, 1.5V Leakage current Refer to Standard product table Paragraph 4.8, in 5 minutes Product symbol : (Example) NMCU Series B case 4V 47µF ±20% NMCU B 0G 476 M T R F tanδ Outline of drawings and dimensions Anode indication belt mark L Refer to Standard product table ΔC/C Surge withstanding tanδ voltage LC △C/C Temperature characteristics H UA, UB Case l Dimensions Case code UA UB L 3.2 3.5 ±0.2 a 1.2 1.8 ±0.2 Capacitance µF 1.0 1.5 2.2 3.3 4.7 6.8 10 15 22 33 47 Code 105 155 225 335 475 685 106 156 226 336 476 2.5 0E Rated voltage (V.DC) 4 6.3 0G 0J UA UB UB UB UA UB UB UB 0~ +20% 0~ +25% 0.36 0.39 0.2CV 0.25CV ±30％ or less Specified initial value Reflow 260°C 10 ± 1 sec. table or less Specified initial value table or less ΔC/C Moisture resistance tanδ no load LC ±30％ or less Specified initial value Paragraph 4.22 table or less Specified initial value 40°C, 90 ~ 95%RH, 500hrs table or less ΔC/C High-temperature tanδ load LC ±30％or less Specified initial value Paragraph 4.23 85°C, The rated voltage is table or less 200％Specified initial applied for 2000 hrs. value table or less Failure rate UA UB UB UB 0.39 0.02CV 0.02CV ΔC/C ±20％ or less tanδ Specified initial value table or less LC Specified initial value table or less ΔC/C Moisture resistance tanδ load LC 10 1A 105 ΔC/C Solder heat tanδ resistance LC Thermal shock Standard value and case size 85 Paragraph 4.24 (Unit : mm) Case size W±0.2 Hmax R±0.3 1.6 1.2 0.7 2.8 1.2 0.7 -20 ~ 0% – tanδ Value shown 0.30 table or less LC a Paragraph 4.8, 120Hz, 1.5V ±10％ or less Specified initial value table or less Paragraph 4.26 Specified initial value table or less Specified –55 initial value W l after the rated voltage is applied.

Repeat this operation 5 times running. ±30％or less 40°C, 90 ~ 95%RH, Specified initial value The rated voltage is applied table or less 200％Specified initial for 500 hrs. value table or less 1% / 1000hrs 85°C. The rated voltage is applied (through a protective resistor of 1 Ω/V). ■Operating Voltage ※The voltage derating factor should be as great as possible. Under normal conditions, the operating voltage should be reduced to 80% or less of the rated.
