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 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

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.

安规电容是指用于这样的场合：即电容器失效后，不会导致电击，不危及人身安全.它包括了X电容和Y电容。

X电容是跨接在电力线两线 (L-N) 之间的电容，一般选用金属化薄膜电容；Y电容是分别跨接在电力线两线和地之间 (L-E, N-E) 的电容，一般是成对出现。

基于漏电流的限制，Y电容值不能太大，一般X电容是uF级，Y电容是nF级。X电容抑制差模干扰，Y电容抑制共模干扰。

Y电容的电容量必须受到限制，从而达到控制在额定频率及额定电压作用下，流过它的漏电流的大小和对系统EMC性能影响的目的。

GJB151规定Y电容的容量应不大于0.1uF。Y电容除符合相应的电网电压耐压外，还要求这种电容器在电气和机械性能方面有足够的安全余量，避免在极端恶劣环境条件下出现击穿短路现象，

Y电容的耐压性能对保护人身安全具有重要意义。

CE word is from the French "Communate Europpene" from the initials, is the meaning of the European Community。"CE" mark is a safety certification mark, the manufacturer is considered open and the passport to enter the European market.

UL is in English Test by insurance Underwriter Laboratories Inc. UL secuity testing is the most authoritative, but also engages im community safety testing and identification of the larger non-governmental organizations.

JFV-X2 Metallized Polypropylene Film Capacitor, is not only with above two approvals(CE& UL), but also with TUV approvals. That must can help to promote this capacitor in your market.
