UVK1H3R3MDD

The UVK1H3R3MDD is a Nichicon UVK series aluminum electrolytic capacitor in a miniature radial-lead can. It provides 3.3 µF capacitance at a 50 V rating with a compact φ5 × 11 mm package and 2 mm lead spacing for space-constrained, general-purpose electronic designs.

Designed for general-purpose applications, this radial-lead capacitor offers a combination of compact size, defined ripple handling and endurance characteristics useful for small power and signal-conditioning circuits operating between −40 °C and 85 °C.

Key Features

• Capacitance & Voltage — 3.3 µF nominal capacitance with ±20% tolerance and a 50 V rated voltage, specified at 120 Hz and 20 °C.
• Miniature Radial Can — Compact φ5 × 11 mm case with 2.0 mm lead spacing (±0.5 mm), suitable for tight PCB layouts and through-hole assembly.
• Temperature & Endurance — Operating range −40 °C to 85 °C with rated endurance of 2000 hours at 85 °C under rated voltage.
• Ripple Current Performance — Low-frequency ripple current 35 mA at 120 Hz and high-frequency ripple current 70 mA at 10 kHz, enabling use in both LF and HF decoupling roles.
• Leakage & Dissipation — Specified leakage current of 4.95 µA and tangent of loss angle (tan δ) measured at 0.25 (20 °C, 120 Hz, 50 V).
• Regulatory — RoHS-compliant construction consistent with Nichicon’s UVK series specifications.
• Packaging — Supplied in bulk/no terminal forming or bag packing for flexible procurement and assembly handling.
• Product Status — Listed with End Of Life status; check availability and replacement options when planning production or repairs.

Typical Applications

• Compact power supply decoupling — Small footprint radial can provides local energy storage and noise suppression in constrained PCB areas.
• Signal conditioning and filtering — Suitable for coupling and bypass duties in small analog and mixed-signal circuits where a 50 V rating and low leakage are important.
• Embedded and consumer electronics — General-purpose use in control boards and modules that require a miniature electrolytic with defined ripple and endurance parameters.

Unique Advantages

• Space-efficient form factor — φ5 × 11 mm can and 2 mm lead spacing minimize board area for compact assemblies.
• Clear performance metrics — Specified ripple currents (120 Hz and 10 kHz), leakage current and tan δ provide measurable parameters for design validation.
• Endurance defined at operating temperature — 2000-hour rating at 85 °C gives a quantifiable life expectation for thermal-stressed designs.
• RoHS compliance — Meets RoHS directive requirements for lead-free assembly environments.
• Flexible packaging options — Bulk or bag packing supports both prototyping and production handling workflows.
