Jianghai Products

Jianghai aluminum electrolytic capacitors are mainly divided into two categories: 1) Large industrial capacitors: CD139 series (screw terminal type, 1000uF-20000uF, 400V-600V), CD135 series (snap-in type, 100uF-10000uF, 200V-600V); 2) Small consumer capacitors: CD11 series (radial lead type, 0.1uF-10000uF, 6.3V-500V), CD26 series (SMD type, 0.1uF-1000uF, 6.3V-100V). Different series are optimized for different application scenarios.

Contact our sales team to select the appropriate series based on your application requirements, voltage, and capacitance needs.

Jianghai film capacitors use metallized polypropylene film technology with main features: 1) Low ESR and ESL, suitable for high-frequency applications; 2) Self-healing characteristics for high reliability; 3) Long lifespan, up to 100,000+ hours; 4) Wide temperature range, -40C to +105C; 5) Good capacitance stability, tolerance +/-5%, +/-10%. Main products include DC-Link capacitors (for PV inverters, inverters), filter capacitors (for power filtering), and snubber capacitors (for IGBT protection).

Explore our film capacitor selection for high-reliability applications requiring long lifespan and low ESR performance.

Jianghai supercapacitor main technical parameters: 1) EDLC: Voltage 2.7V-3.0V, capacitance 1F-3000F, ESR 0.3mOhm-200Ohm, cycle life 500,000+ cycles; 2) Lithium-ion capacitors: Voltage 3.8V, capacitance 100F-1000F, energy density 3-4x higher than EDLC, operating temperature -40C to +65C. Jianghai supercapacitors feature high power density (up to 10kW/kg), fast charge/discharge (seconds), and environmental-friendly.

Jianghai aluminum electrolytic capacitor lifespan calculation formula: Lx = L0 x 2^((T0-Tx)/10) x (V0/Vx)^n. Where L0 is rated lifespan (hours), T0 is rated temperature (usually 85C or 105C), Tx is actual working temperature, V0 is rated voltage, Vx is actual working voltage, n is voltage coefficient (usually 2-3). Example: CD139 series rated lifespan 10,000 hours at 85C, actual working temperature 65C, then expected lifespan is approximately 40,000 hours. Film capacitors and supercapacitors have longer lifespans, typically 10+ years.
