SUREPHON 35+10uF ±5% 370V/440V CBB65B Dual run circular start capacitor, A Class, 10000 AFC. Capacitor Diameter (63.5 mm/2.5 inches) Height (100 mm/3.93 inches), Capacitance Range: ±5% (std.). Frequency: 50-60Hz. Operating Temperature Range: -40°C to +70°C / -104°F to +158°F. Built to the TOUGHEST U.S. standards for AC motor run capacitors. Designed to the highest standards - meets EIA-456-A and IEC 60252-1:2001 specifications. With UL certificate:E325324 (Certificate No.) No wiring or adapter changes are required. There are three terminals on the top of the AC capacitor: the compressor motor is marked "Herm," the fan is marked "Fan," and the common line is marked "C." For AC Unit Fan Motor Start, Heat Pump, or Condenser Straight Cool. Surephon is the only manufacturer of the capacitor integrated production in the world, ranging from electrical film production for capacitors, film metallization, spare parts (plastic parts and explosion-proof assemble) to capacitor assemble.

Structure:Cylinder/ellipsoidal aluminium case, built in reliable explosion-proof device.

Features: Low dissipation,stable capacitance, good insulation, good self-healing,reliable quality, long life,anti-striking current,strong overload capability etc.

Main use: Applied to 50/60Hz AC motor for starting and running,such as air conditioner, comperssors.refrigerator,torage welding machine, motor, light etc.

This kind of capacitor utilizes hermetically-sealed construction. When the inner core is broken down during the usage of capacitor,polypropylene film (BOPP). the main material of core,is decomposed in the high temperature resulted from the breakdown, causing a lot of gas which cannot be released.
The gas in the capacitor increases the inner pressure, which deforms the cover of capacitor and makes it bulge outward.As the rivet connects terminals,insulated bowl,sealing ring and capacitor cover as the assembly.other parts of this assembly move above with the capacitor cover.
Copper foil sticks to the explosion-proof block which is fixed in the capacitor. When the capacitor cover moves above,copper foil cannot move and is pulled off if the capacitor inner pressure meets a certain level. In this way, the core of the capacitor disconnects with the outside power supply and breakdown of core is terminated.so as to activate protection.
