Technical Specifications
| Parameter | Description |
| Polarity | DC electrolytic capacitors are polarized. Ensure correct polarity to prevent short circuits or damage. Bipolar capacitors are available for applications with uncertain or variable polarity. Not suitable for AC applications. |
| Bipolar Capacitors Usage | Suitable for pulse circuits and polarity reverse circuits. Not applicable for pure AC or high ripple current circuits. |
| Voltage Usage | Do not apply voltage greater than rated voltage. Recommended working voltage is 70-80% of rated voltage for extended life. |
| Ripple Current | Do not allow ripple current to exceed permissible limits. Excessive ripple current causes heating, capacitance reduction, and damage. Generally, do not exceed 80% of the rated ripple current. |
| Fast 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 | Life is generally doubled for every 10C reduction in operating temperature from the rated temperature. Formula provided for calculation: Lx = L0 * 2(T0-Tx)/10 (where Lx is useful life at actual operating temperature Tx, L0 is useful life at maximum operating temperature T0). |
| Operating Frequency | Capacitance is typically measured at 100Hz or 120Hz. Capacitance decreases and tg increases with higher frequencies, leading to increased ambient temperature. |
| Storage and Handling | Capacitors stored for extended periods may experience increased leakage current and reduced withstand voltage. Before use, apply rated DC voltage gradually. |
| Case Insulation | The capacitor case is not insulated from the cathode terminal. Insulation measures are required at the mounting point if case insulation is necessary. |
| Force on Terminals/Leads | Do not apply excessive force to terminals or leads to prevent breakage, separation, or internal connection failure. |
| Lead Bending | 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 cleaning solvents (Methanol, Isopropanol, Ethanol, Isobutanol, Petroleum Ether, Propanol, general detergents). Avoid halogenated solvents (trichlorethylene, xylene, acetone) to protect the capacitor body. |
| Soldering | Maintain a distance between the soldering iron and the plastic insulating sleeve. Recommended soldering temperature is within 260C for no more than 10 seconds to avoid damage. |
| Hole Layout on PCB | Mounting 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 body. |
