1 NIC Components Corp. Low ESR Capacitors

2 What is ESR? ESR is an abbreviation for Equivalent Series Resistance, the characteristic representing the sum of resistive (ohmic) losses within a capacitor. While ESR is undesirable, all capacitors exhibit it to some degree. Capacitor manufacturers look to ways to reduce the ESR of the capacitor…

6 Low ESR Electrolytic Capacitors NIC Components Corp. Product Offering

7 Low ESR Electrolytic Capacitors Aluminum - Liquid Electrolyte: NACZ, NACZF, NACX  V-Chip = larger size SMT  Lowest Cost of SMT types  Highest capacitance values (to 6800uF)  Highest ESR of the low ESR family  Wears out ( electrolyte dissipation ) under high temperature operation - Crosses to: » Elna “RVH” series » Nichicon “UWF” & “UUJ” series » Panasonic “FC” series » Sanyo “CV-GV”

8 Low ESR Electrolytic Capacitors Aluminum Hybrid Electrolyte: NSPE  V-Chip  22uF ~ 820uF  Moderate Cost  KHz ESR  BEST VALUE OF LOW ESR FAMILY  Wears out ( electrolyte dissipation ) under high temperature operation

9 Low ESR Electrolytic Capacitors Aluminum Solid* Electrolyte: NSP  Small Flat Chip ( D case )  2.2uF ~ 270uF  0.010ohm 100KHz ESR Specs  BEST LONG TERM PERFORMANCE OF LOW ESR FAMILY  Solid Electrolyte does not exhibit WEAR-OUT  LOWEST ESR & HIGHEST COST NSP Crosses to: Panasonic - “CD” series ( same specs & sizes) Kemet – “A700” series Solid * = “ OS-CON = Organic Semi-Conductor ”, “Polymer Aluminum”, “Solid Aluminum ” (all terms for the same thing)

10 Low ESR Electrolytic Capacitors Aluminum Solid* Electrolyte: NSPZ  V-Chip  15uF ~ 680uF  ohm 100KHz ESR  BEST LONG TERM PERFORMANCE OF LOW ESR FAMILY  Solid Electrolyte does not exhibit WEAR-OUT  LOW ESR & HIGH COST NSPZ Crosses to: Sanyo “SV” & “SVP” & “SVQP” series “OS-CON” Nichicon “NA” series Vishay “94SV”, “OS-CON” United Chemi-Con - “PX” series Solid * = “ OS-CON = Organic Semi-Conductor ”, “Polymer Aluminum”, “Solid Aluminum ” (all terms for the same thing)

11 Low ESR Electrolytic Capacitors Tantalum Polymer* Cathode: NTP  Small Flat Chip (A ~ D sizes)  3.3uF ~ 470uF  ohm 100KHz ESR  Lowest ESR Tantalum type  Polymer Cathode suppressions combustion = improved safety - HIGHEST COST of tantalum types NSP Crosses to: NEC - “PSL” & “PSN” series ( same specs & sizes) Kemet – “KO-Cap” - “T520” series Sanyo- “POS-Cap” – “TPA”, “TPB”, “TPC” series Nichicon- “F55” series * Also referred to “Polymer Tantalum”, “KO-CAP” or “POS-CAP” (all terms for the same thing)

12 Low ESR Electrolytic Capacitors Tantalum Standard Cathode (MnO 2 ): NTC-L  Small Flat Chip (B ~ D sizes)  10uF ~ 330uF  0.10 ~ 0.70ohm 100KHz ESR Specs  Solid Electrolyte does not exhibit WEAR-OUT  Lower costly than NTP ( polymer cathode ) series NTC-L Crosses to: » AVX “TPS” series » Cornell Dubilier “SHJL” series » Kemet “T494” & “T495” series » NEC “SVZ” » Vishay – Sprague “593D”

13 Low ESR Electrolytic Capacitors Aluminum Liquid Electrolyte: NRSZ, NRSX, NRSY, NRSJ, NRSG & NRSX  Radial can = largest sizes  Lowest Cost ( up to ½ the cost of SMT versions )  Highest capacitance values ( to 15,000uF )  Lowest ESR ( to ohm ) of leaded type products  Wears-out ( electrolyte dissipation ) under high temperature operation
