Technical Specifications
| Specification | Description | Notes |
|---|---|---|
| Polarity | DC electrolytic capacitors are polarized. Ensure correct polarity to prevent short circuits or damage. Use bipolar capacitors if polarity is uncertain. Not suitable for AC applications. | Bipolar capacitors are for pulse and polarity reverse circuits, not pure AC or high ripple. |
| Voltage | Do not exceed rated voltage. Recommended working voltage is 70-80% of rated voltage for extended life. | Exceeding rated voltage increases leakage current and may cause damage. |
| Ripple Current | Do not allow excessive ripple current to pass through the capacitor. Generally, do not exceed 80% of the rated current. | Exceeding ripple current limits causes heat, capacitance reduction, and damage. |
| Charge/Discharge Circuits | Use specially designed capacitors for circuits with rapid charge and discharge cycles. | Rapid cycles can shorten lifespan due to capacitance decrease and heat rise. |
| Operating Temperature | Capacitor characteristics vary with temperature. Lower temperatures ensure longer life. | Higher temperatures increase capacitance and leakage current, decrease tg. Lower temperatures decrease capacitance and leakage current, increase tg. |
| Temperature & Life Relationship | For every 10 decrease in temperature, lifespan doubles at rated temperature. Formula provided for calculation. | Formula: Ls = L0 * 2^((T0-Tx)/10) * sqrt((I0/Ix)^2 * (Tm-Tm)/(Tm-T)) |
| Operating Frequency | Capacitance is typically measured at 100Hz or 120Hz. Capacitance decreases and tg increases with higher frequencies, leading to increased ambient temperature. | Be aware of frequency effects on performance. |
| Storage | For capacitors stored long-term, apply rated DC voltage gradually before use. | Long storage can increase leakage current and decrease withstand voltage. |
| Case Insulation | The capacitor case is not insulated from the cathode terminal. | Insulation measures are required at the mounting point if the case needs to be insulated from the circuit. |
| Force on Terminals/Leads | Do not apply excessive force to terminals and leads. | Excessive force can cause breaks, separation, and internal connection failure. |
| Bending Leads | Maintain a 2mm safe spacing between the bend and the capacitor body when bending leads for horizontal mounting. | Failure to do so may cause internal structural damage. |
| Cleaning | Clean circuit boards with recommended solvents (Methanol, Isopropanol, Ethanol, etc.). Do not use halogenated solvents. | Avoid solvents like trichlorethylene, xylene, or acetone to protect sleeve, marking, and sealing materials. |
| Soldering | Soldering temperature should be within 260 for no more than 10 seconds. Keep soldering iron away from plastic sleeves. | Avoid damage to the capacitor unit. |
| Hole Layout | Ensure mounting hole spacing on PCBs matches lead spacing. Consider hole layout carefully to prevent solder splashing onto the sleeve. | Incorrect spacing can cause stress on leads, short circuits, and damage. |
