UKA1V332MHD

The UKA1V332MHD is a polarized aluminum electrolytic capacitor in a radial‑lead can designed for through‑hole applications. It delivers 3.3 mF of capacitance at a 35 V rating with a wide operating temperature range from −55 °C to +105 °C, making it suitable for demanding audio and equipment‑level power applications.

Engineered for long endurance and elevated ripple handling, this part combines high capacitance density with robust electrical characteristics — including specified low‑frequency and high‑frequency ripple currents, controlled dissipation factor, and defined leakage current — to support power filtering and decoupling in precision audio systems and other equipment that require reliable, long‑life bulk capacitance.

Key Features

• Capacitance & Voltage — 3300 µF nominal capacitance at 35 V provides substantial bulk energy storage for power-rail smoothing and decoupling.
• Wide Temperature Range — Rated for −55 °C to +105 °C to support operation across harsh ambient conditions.
• Endurance — Qualified for 2000 hours at 105 °C with specified limits on capacitance change, dissipation factor, and leakage current after test.
• Ripple Current Capability — Low‑frequency ripple current 1.61 A (120 Hz) and high‑frequency ripple current 1.851 A (10 kHz) for effective handling of AC stress on power rails.
• Dissipation Factor (tan δ) — Specified tan δ 0.2 measured at 20 °C, 120 Hz, supporting predictable loss behavior in audio and power applications.
• Leakage Current — Measured leakage current 3465 µA, with datasheet leakage current limits defined by C and V test conditions.
• Package & Mounting — Radial lead, can‑style case with nominal size φ16 × 35.5 mm (L: 3.55 × D: 1.6 cm) and 7.5 mm lead spacing for straightforward through‑hole assembly and hand or automated insertion; available bulk/bag packing.
• Qualification — AEC‑Q200 listed in the product specifications for applications that require component stress qualification for passive devices.

Typical Applications

• High‑grade Audio Equipment — Bulk power smoothing and reservoir capacitance in amplifiers, DAC power supplies, and audio filtering stages where wide temperature capability and controlled loss are important.
• Through‑Hole Power Supplies — Input/output filtering and bulk energy storage on through‑hole power boards requiring robust ripple handling and long endurance at elevated temperature.
• Industrial and Equipment Electronics — Support for power rails in instruments and appliances operating across broad ambient temperatures and requiring long operational life.

Unique Advantages

• High Bulk Capacitance at 35 V: 3300 µF provides substantial energy storage to stabilize DC rails and reduce ripple in power systems.
• Designed for Wide Temperature Operation: −55 °C to +105 °C rating enables use in environments with large temperature swings without compromising basic performance specifications.
• Defined Endurance Performance: 2000 hours at 105 °C with controlled limits on capacitance change, dissipation factor, and leakage current gives predictable long‑term behavior.
• Measurable Ripple Handling: Specified ripple current values at 120 Hz and 10 kHz support designs with both low‑ and high‑frequency AC components on the supply rails.
• Through‑Hole Form Factor: Radial lead can and 7.5 mm lead spacing simplify PCB layout and assembly for legacy and serviceable designs.
• AEC‑Q200 Qualification: Inclusion in the AEC‑Q200 listing supports use in designs that require passive component stress qualification.
