The time constant (s) of a capacitor is the product of IR and capacitance: s = MΩ ×μF Urms t Up-peak 1.6 Rated A.C peak voltage Upeak Rated A.C peak voltage, permissible A.C peak voltage in continuous operation. 1.7 Voltage Rise Time du/dt This value shows the maximum voltage rise or fall time, it is expressed in volts per microsecond, and cannot overcome. 1.8 Maximum non-repetitive rate of voltage rise (du/dt)s Peak rate of voltage rise that may occur non-repetitively and briefly in the event of a fault. 1.9 Voltage Test between terminals Ut-t Routine test of all capacitors conducted at room temperature, prior to delivery. A further test with 80% of the test voltage stated in the data sheet may be carried out once at the user’s location. 1.10 Voltage Test between terminals and case Ut-c Routine test of all capacitors between short-circuited terminals and case, conducted at room temperature. May be repeated at the user’s location. 1.17 Resonant Frequency Fr The capacitance and self-inductance of any capacitor form a series resonant circuit.

But the following exceptions to the rule are possible: ·Capacitors in aluminum cases with voltage ratings up to 3600 V and capacitors in rectangular steel cases may also be positioned horizontally. ·At higher voltages or for capacitors in round steel cases, horizontal positioning is also permissible. But consult the manufacturer first. 1.26 Rated Energy Contents Wn Energy stored in the capacitor when charged at rated voltage. Wn = 1/2 x Cn x (Un)2 1.27 Clearance in air L The shortest distance between conducting parts of the terminals or between terminals and case. 2.3 1.28 Creepage distance K The shortest distance along an insulated surface between conducting parts of the terminals or between terminals and case. 1.29 Altitude The maximum allowable altitude is 2000 meters. As the barometric pressure decreases, the terminal arc-over susceptibility increases. Heat cannot be properly dissipated operating at high altitude and can result in high losses and eventual failure. 1.30 Storing Temperature The range over which the capacitor can be stored without any applied voltage, with no degradation is - 40 to + 85 ˚C. 1.31 Life Expectancy Le Above all, the expected life of the capacitors depends on the internal temperature during operation, and the field strength in its dielectric. Life expectancy versus voltage Le = Ln x (Un/Uw)8 Le = Life expectancy at operating voltage (h) Ln = Life expectancy at nominal voltage (h) Un = Nominal voltage (v) Uw = Operating voltage (v) EACO Capacitor Inc. www.eaco.com 2.1 When mounting capacitors with overpressure disconnectors, make sure that the elastic elements of the fuse are not impeded. This means: ·The connecting leads must be sufficiently elastic. ·There must be enough space left for expansion above the terminals of aluminum-cased capacitors (stated for the individual type). ·The folded crimps must not be held by retaining clamps. ·The elastic bottom of capacitors in round steel cases must be free to move. 1.23 Hotspot Temperature Ths Temperature at hottest spot inside the capacitor Life expectancy versus temperature Le = LTo x 2(To-Ths)/7 Le = Life expectancy at operating temperature (h) LTo= Life expectancy at 70˚C (h) To = Reference temperature (70˚C) Ths = Hot spot case temperature (≤ 70˚C) 2. Mounting and Operating Instructions Minimum terminal connection cross-sections in accordance with VDE/DIN 0100 part 523 and 430,group 2. For the electrical terminals on ceramic lead-throughs only flexible leads should be used so that these lead-throughs are guarded against mechanical stress. The outer leads of the capacitor should be dimensioned so that no heat is conducted into the component. You are advised to scale these leads so that heat is conducted away from capacitor terminals. 2.4 Grounding Either a threaded bolt or a strap serves for grounding to VDE 0100. Grounding is omitted for single-pole and fully insulated capacitors. The layer of varnish beneath the clamp should be removed when grounding with a metal clamp. 2.5 Safety precautions Observe appropriate safety precautions in use (self-recharging phenomena and the high energy contained in capacitors). 2.6 Solder conditions for radial and axial units on PCB The soldering temperature must be set to keep the temperature inside the capacitors below the following general limits: Solder bath temperature 260 ±5˚C, Soldering time 4s for radial units with leads pitch P>10mm. When soldering the leads, make sure the capacitors are not damaged through excessive heat. This means: ·Lead wires with a cross-section of > 1.5 mm2 should not be soldered but clamped (soldering would require too much heat). ·Do not solder at spots where heat concentrates, otherwise there is a risk that the solder joint of the tags melts. sales@eaco.com design@eaco.com Tel:0086 757 2230 1650 Fax: 0086 757 2230 1658 STD-2000-1.0-57 / IGBT Snubber ·Filler material consists of paper. ·Shipping cartons are sealed with recycled paper adhesive tape to ensure material of the same kind for disposal. ·We take our packaging back (especially product-specific packaging made of plastic).

Another problem with lifetime statements is that they do not inform about failures during the “rated” lifetime, and – in turn – may create the impression that after the expiration of the “rated” lifetime, the capacitor shall be exhausted, or fail. Any engineer will agree from own experience that in reality, there are components which may last much longer even under harder conditions, whilst others may fail prematurely. 2.0 +0/-0.5mm from capacitor body or seating plane Heat-absorbing board, (1.5±0.5)mm thick , between capacitor body and liquid solder No visible damage 2%for STB/ STC/ STE/ SHB/ STR/ SRB 5% for STB/ STC/ STE/ SHB/ STR/ SRB As specified in sectional specification 3. End of use and disposal The materials used in capacitors for power electronics from EACO do not exceed the limits for chemical substances specified in the following national regulations: ·Chemicals prohibition regulation, ·CFC halogen prohibition regulation. Our capacitors for power electronics contain no means of impregnation with PCB. Capacitors without PCB for power electronics are not explicitly mentioned in the waste qualification regulations. From this it could be deduced that they do not have to be disposed of as “waste requiring special supervision”. Because of our special commitment to and responsibility for the environment, we ask you to take every care when disposing of capacitors. We recommend that you drain the impregnation oil out of the capacitor and send it to an oil refuse depot. The emptied capacitor can then be disposed of as a grease and oil soiled item of apparatus. In any case it is advisable to consult a waste disposal facility and to find out about the applicable regulations in force. 5.2 Failure Modes Plastic dielectric film capacitors can undergo two classic failure modes: open or shorts or high resistance shorts. In addition to these failures, capacitors may fail due to capacitance drift, instability with temperature, high dissipation factor or low insulation resistance. Failures can be the result of electrical, mechanical or environmental overstress, due to dielectric degradation during operation. 5.3 Operating life The operating life of the capacitors depends on the internal temperature during operation, and the field strength in its dielectric. The capacitors have been designed for an average service life of 100,000h (permitted failure rate 3%). These values are rated for the hotspot temperatures specified in the selection charts. The following diagram demonstrates the correlation between service life, temperature, and operating voltage. 4. Delivery and packing In the packing of products, EACO naturally supports the needs of protection of the environment. In the words: ·Use of packing made of environmentally compatible materials. Reduction of packaging to the necessary minimum. We have implemented the following measures to ensure compliance with regulations governing the handling and disposal of commercial waste. ·Use of pallets. ·Securing of pallets by straps and edge guards of environment-friendly plastic (PE or PP). Stretch and shrink film (PE) are used. ·Shipping cartons are identified by the RESY symbol. · Separating layers for pallets and cartons are primarily of paper or cardboard.
