A photoflash capacitor is an electrolytic capacitor used in flash cameras, professional flashes, and also in solid-state laser power supplies. Their usual purpose is to briefly power a high-voltage flash tube, used to illuminate a photographic subject or optically pump a laser rod. As flash tubes require very high current for a very short time to operate, photoflash capacitors are designed to supply high discharge current pulses without excessive internal heating.

Photoflash Aluminum Electrolytic Capacitors are very special capacitors and need very high quality and professional  technology. I have friends told me that jb Capacitors Company produce very good quality photoflash electrolytic capacitors. JSU Series--Photo-Flash-Lug-Aluminum-Electrolytic-Capacitors. Here is the datasheet link:http://www.jbcapacitors.com/Aluminum-Electrolytic-Capacitors/JSU-Photo-Flash-Lug-Aluminum-Electrolytic-Capacitor.html

jb capacitors company is very strong on Aluminum electrolytic capacitors, including snap-in, screw type and lug type.

Snap-in Aluminum Electrolytic Capacitors is widely used on power supply. If the end product is industrial motor, some customer may requires to add a mica sheet of plastic layer or other non-flammable material between the Aluminum electrolytic body and PCB. As we know, the motor has vibrations, and it keeps running 24 hours, so that the capacitor will be very hot. The piece of plastic layer is used as insulation to prevent the capacitor from shorting itself.

Motor Start Metallized Polyproyplene Film Capacitors ( Motor Run capacitors ) , in China, also called CBB60, CBB61, CBB65.

jb Capacitors Company produce 18 kinds of motor starting capacitors, with different terminals.

Tony: I heard that Brand Electronicon discontinued E23 series motor starting film capacitors since last year.
Peter: Really ? how about Iskra motor starting capacitors ?
Terry : I bought Iskra capacitors, but their prices are too high.
Anna: I used to use Iskra brand, but now I use jb Capacitors Brand, quality is very good, and their prices are very reasonable.
I buy from jbcapacitors JFS--17 series for many years.
Piotry: Yes, really good brand, I buy jb capacitors JFS-13 series for a long time, their delivery time is very fast too.
I am going to buy their JFS--6 series soon. The box type with terminals motor run capacitors are also very popular.
I also received information from jb capacitors, seems their JFS-17 can replace Electronicon E23 series.
Tony: Sounds great !! I will contact with jb capacitors and check soon.

jb capacitors company not only produce MKT MKP Film capacitors, also produce high quality Screw 
terminals Aluminum Electrolytic capacitors, some people called Large can aluminum electrolytic capacitors, I.E. Snap-in, Screw, Lug type. Long load life, high ripple current...

Recently jb strongly recommend screw type aluminum electrolytic capacitors, with very high quality, widely use in power supply, UPS, Welding Machines, filter etc...

See below our strong series:
JMJ--Screw terminal aluminum electrolytic capacitors, 2000hours at 85C'---cross: Epcos B41456,B41458/ B43456,B43458/ B43564, B43584/ B43455, B43457 CDE: CGS series
JML--Screw terminal aluminum electrolytic capacitors, 2000hours at 105C'--Cross:

jb capacitors company strongly recommend:

JFQ-Box type double sided metallized polypropylene film capacitor

This type capacitors capacitance range is wide, voltage is up to 2000V, can cross to many high end European brands:

Capacitance Range: 0.00022uF ~ 3.9uF
Rated Voltage: 250V, 400V, 630V, 1000V, 1400/1600V, 2000V.DC
Lead Spacing: 7.5mm, 10mm, 15mm, 22.5mm, 27.5mm

Cross Reference:
Arcotronics(Kemet) : R76 series
EVOX RIFA: PHE450 series
Vishay: MMKP 383 Series
Wima: MKP 10,
Philkor: PCMP384 series etc...

Applications: electronic ballast, frenquency control, lighting etc...

Polyester films, are clearer and a higher quality than lower grade films, which tend to be foggy. Premium films also endure extreme environments and severe stress conditions more favorably. Films with higher polyester content are more rigid and feel thicker than films with more adhesive content.

Polypropylene film is softer than polyester, but still has excellent clarity. These films have strong chemical resistence, good color stability over printed sheets, and good elasticity which allows the film to lay extremely flat. Due to its softness and flatness, polypropylene films are most often used in single-sided laminating.

When a capacitor discharges its charge throught a resistor, the charge of the capacitor decreases with time. The decreasing charge follows an exponential decay curve.
