UVR2G101MRD

The UVR2G101MRD is an aluminum electrolytic, radial-lead capacitor from Nichicon’s UVR series, offering 100 µF capacitance at a 400 V rated voltage. It is designed for general-purpose power filtering and smoothing in electronic systems, with a compact φ20 × 40 mm can and 10 mm lead spacing for through-hole assembly.

Targeted at applications such as consumer entertainment electronics and general-purpose power electronics, the part combines defined electrical performance (tanδ, leakage, ripple current) with a specified endurance of 2000 hours at 85°C for predictable lifetime behavior.

Key Features

• Capacitance & Voltage — 100 µF nominal capacitance with a rated voltage of 400 V, suitable for high-voltage filter and smoothing duties.
• Electrical Loss and Leakage — Specified tangent of loss angle (tanδ) of 0.25 measured at 20°C, 120 Hz, and a defined leakage current of 1700 µA for predictable bias characteristics.
• Ripple Current Ratings — Low-frequency ripple current 550 mA (120 Hz) and high-frequency ripple current 880 mA (10 kHz) to support AC ripple handling across typical power line frequencies.
• Endurance — Rated life of 2000 hours at 85°C with performance criteria (capacitance change, tanδ, leakage) specified after recovery to 20°C.
• Mechanical & Mounting — Radial lead, can-style package (φ20 × 40 mm length) with 10 mm lead spacing and bulk/bag packing options for through-hole assembly and manual or machine insertion.
• Operating Range & Compliance — Operating temperature range −40°C to +85°C and RoHS-compliant construction.

Typical Applications

• Consumer Entertainment Electronics — Bulk and smoothing capacitance for power supplies in audio, video and set-top equipment, aligned with the UVR series positioning for entertainment devices.
• Power Supply Filtering — High-voltage DC bus filtering and decoupling where 400 V rated components and 100 µF capacitance are required.
• General-Purpose Electronics — Through-hole designs needing a compact, radial aluminum electrolytic for energy storage and transient suppression.

Unique Advantages

• High voltage capability: 400 V rating enables use in higher-voltage DC bus and power rail applications without series stacking.
• Predictable loss characteristics: Specified tanδ (0.25 at 20°C, 120 Hz) provides a clear basis for thermal and dissipation planning in designs.
• Defined ripple handling: Published ripple currents at 120 Hz and 10 kHz (550 mA / 880 mA) help size components for both low- and high-frequency ripple environments.
• Endurance specification: 2000 hours at 85°C with post-test limits on capacitance, tanδ and leakage supports life-cycle planning and reliability estimates.
• Compact radial format: φ20 × 40 mm can with 10 mm lead spacing fits common through-hole assemblies while keeping board footprint small.
• RoHS compliant: Meets RoHS directive requirements for lead-free assemblies and regulatory compatibility.
