Technical Specifications
| Item | Description |
| Polarity | DC electrolytic capacitors are polarized. Ensure correct polarity to avoid short circuits or damage. Use bipolar capacitors when polarity is not fixed or determined. DC electrolytic capacitors are not suitable for AC applications. Bipolar capacitors are for pulsating or polarity-reversing circuits, not pure AC or high ripple. |
| Voltage | Do not exceed the rated voltage. Recommended working voltage is 70-80% of rated voltage for extended lifespan. Exceeding rated voltage increases leakage current and may damage the capacitor. |
| Ripple Current | Do not allow excessive ripple current. Exceeding permissible ripple current causes heat, capacitance reduction, and damage. Ripple current should not exceed 80% of the rated value. |
| Circuit Application | 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 temperatures ensure longer life. Capacitance and leakage current increase, while tg decreases at higher temperatures. Capacitance and leakage current decrease, while tg increases at lower temperatures. |
| Temperature & Life Relationship | Life is temperature-dependent. A 10 reduction in operating temperature can double the lifespan compared to rated temperature. Formula provided for calculation: Lx = L0 * 2(T0-Tx)/10 where Lx is the useful life at actual operating temperature Tx, and L0 is the useful life at maximum operating temperature T0. (Note: The provided formula in the source text appears to be incomplete or incorrectly transcribed for direct calculation without further context on its variables like T, Im, I0, Ix). |
| Operating Frequency | Capacitance is typically measured at 100Hz or 120Hz. Capacitance decreases and tg increases with rising frequency, leading to higher ambient temperatures. |
| Storage | For capacitors stored for a long time, gradually apply rated DC voltage before use. Long storage may increase leakage current and decrease withstand voltage. |
| Case Insulation | The capacitor case is not insulated from the cathode terminal. If insulation is required, implement it at the mounting point. |
| Mechanical Stress | Avoid applying 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 solvents (Methanol, Isopropanol, Ethanol, Isobutanol, Petroleum Ether, Propanol, detergents) for cleaning. Avoid halogenated solvents (trichlorethylene, xylene, acetone) to protect the sleeve, marking, and sealing materials. |
| Soldering | Maintain distance between the soldering iron and the plastic sleeve. For dip soldering, keep temperature within 260 and duration under 10 seconds to prevent damage. |
| Hole Layout | Ensure circuit board hole spacing matches lead spacing to avoid stress on leads. Consider hole layout carefully to prevent solder splashing onto the capacitor body. |
