Technical Specifications
| Spec | Description |
| Polarity | DC electrolytic capacitors are polarized. Polarity is marked on the capacitor body. Reversed voltage may cause short circuit or damage. Use bipolar capacitors when polarity is not determined or unknown. DC electrolytic capacitors cannot be used for AC applications. |
| Bipolar Capacitors | Used only in pulse circuits and polarity reverse circuits. Not applicable in pure AC or high ripple current circuits. |
| Operating Voltage | 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 excessive ripple current. Ripple current exceeding the permissible value will cause heating, capacitance reduction, and damage. Generally, do not exceed 80% of the rated ripple current. |
| Charge/Discharge Circuits | For circuits with rapid charge/discharge cycles, use specially designed capacitors 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 | Life is related to operating temperature. Reducing temperature by 10 can double the lifespan at rated temperature. Formula provided for calculation. |
| Operating Frequency | Capacitance is usually measured at 100Hz or 120Hz. Capacitance decreases and tg increases with higher frequencies, leading to increased ambient temperature. |
| Storage | Capacitors stored for a long time may have increased leakage current and reduced withstand voltage. Before use, apply rated DC voltage gradually to the rated voltage. |
| Case Insulation | The capacitor case is not insulated from the cathode terminal. If insulation is required, take insulation measures at the capacitor's mounting point. |
| Force on Terminals/Leads | Do not apply 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 distance from the capacitor body to avoid internal structural damage. |
| Circuit Board Cleaning | Do not use halogenated solvents (e.g., trichlorethylene, xylene, acetone) for cleaning. Recommended solvents include methanol, isopropanol, ethanol, isobutanol, petroleum ether, propane, and commercial detergents. |
| 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 unit. |
| Hole Layout on PCB | Hole spacing should match lead spacing. Improper spacing can cause stress on leads, leading to short circuits or damage. Consider hole layout carefully to prevent solder splashing onto the capacitor. |
