Technical Specifications
| Item | Description |
| Polarity | DC electrolytic capacitors are polarized. Ensure correct polarity to avoid short circuits or damage. Use bipolar capacitors for uncertain polarity. DC electrolytic capacitors are not for AC applications. |
| Bipolar Capacitors Usage | Suitable for pulse circuits and polarity reverse circuits only. Not applicable for pure AC or high ripple current circuits. |
| Voltage Application | Do not apply voltage greater than the rated voltage. Recommended working voltage is 70-80% of rated voltage for extended life. |
| Ripple Current | Do not allow ripple current to exceed the permissible value, generally not more than 80% of the rated current, to prevent overheating and damage. |
| Charge/Discharge Circuits | Use specially designed capacitors for circuits with rapid, repeated charge and discharge cycles to prevent damage, capacitance decrease, and heat rise. |
| Operating Temperature | Capacitor characteristics vary with temperature. Lower operating temperatures ensure longer life. |
| Temperature and Life Relationship | Generally, reducing operating temperature by 10 doubles the lifespan compared to rated temperature. Formula provided for calculation: Ls = L0 * 2^((T0-Tx)/10) * (I0/Ix)^m, where L0 is useful life at max temp T0 with ripple I0, Tx is actual temp, Ix is actual ripple, and m is an exponent. |
| Operating Frequency | Capacitance is typically measured at 100Hz or 120Hz. Capacitance decreases and tg increases with higher frequencies, leading to increased ambient temperature. |
| Long-Term Storage | Capacitors stored for extended periods may experience increased leakage current and reduced withstand voltage. Before use, gradually apply DC voltage up to the rated voltage. |
| Case Insulation | The capacitor case is not insulated from the cathode terminal. If case insulation is required, it must be implemented at the mounting point. |
| Force on Terminals/Leads | Avoid applying excessive force to terminals or leads to prevent breakage, separation, or internal connection failure. |
| Bending Leads | When bending leads for horizontal mounting, maintain a 2mm safe spacing from the capacitor body to prevent internal structural damage. |
| Circuit Board Cleaning | Use recommended solvents like methanol, isopropanol, ethanol, isobutanol, petroleum ether, propanol, and general detergents. Avoid halogenated solvents (trichloroethylene, xylene, acetone) to protect the sleeve, marking, and sealing materials. |
| Soldering | Keep soldering irons away from plastic sleeves. Recommended soldering temperature is within 260 for no more than 10 seconds to avoid damaging the capacitor element. |
| Hole Layout on PCB | Mounting hole spacing should match lead spacing to prevent stress on leads. Consider hole layout carefully to avoid solder splashing onto the vinyl sleeve. |
