UVK2E3R3MED

The UVK2E3R3MED is a miniature aluminum electrolytic capacitor from Nichicon’s UVK series. It is a radial-lead, polarized, standard-type capacitor offering 3.3 µF capacitance at a 250 V rating for general-purpose electronic designs.

Designed for compact circuits, this capacitor combines a small φ6.3 × 11 mm can and 2.5 mm lead spacing with measurable electrical characteristics—low-frequency and high-frequency ripple current ratings, defined leakage current, and a 2000-hour endurance at 85°C—making it suitable for space-constrained, general-purpose power and signal applications.

Key Features

• Capacitance & Voltage — 3.3 µF nominal capacitance with a rated voltage of 250 V and tolerance of −20% to +20%.
• Miniature Package — Compact radial can with dimensions φ6.3 × 11 mm and 2.5 mm lead spacing (±0.5 mm), enabling tighter PCB layouts.
• Electrical Performance — Dissipation factor (tan δ) of 0.20 measured at 20°C, 120 Hz; low-frequency ripple current 40 mA (120 Hz) and high-frequency ripple current 64 mA (10 kHz).
• Leakage Current — Specified leakage current of 122.5 µA after rated voltage application, per Nichicon measurement conditions.
• Temperature & Endurance — Operating temperature range −40°C to +85°C with an endurance rating of 2000 hours at 85°C under rated voltage.
• Compliance — RoHS compliant, meeting applicable directive requirements listed by the manufacturer.

Typical Applications

• General-purpose power filtering — Compact 250 V polarized capacitor for smoothing and ripple reduction in general electronics where space is limited.
• Decoupling on PCBs — Radial-lead mounting and small can size allow placement close to components for decoupling in PCB assemblies.
• Space-constrained designs — Miniature dimensions make it suitable for compact modules and assemblies requiring reliable capacitance at elevated voltages.

Unique Advantages

• Small footprint: φ6.3 × 11 mm can and 2.5 mm lead spacing reduce board area compared with larger radial electrolytics.
• Clear electrical specs: Specified tan δ, ripple currents (low and high frequency), and leakage current enable straightforward selection and verification in designs.
• Defined endurance: 2000 hours at 85°C with rated voltage provides a measurable reliability baseline for thermal-stressed applications.
• Wide operating temperature: −40°C to +85°C rating supports deployment across a broad range of environmental conditions.
• RoHS compliance: Conforms to RoHS directive requirements as stated by the manufacturer.
