UVR1A101MDD

The UVR1A101MDD is a miniature radial-lead aluminum electrolytic capacitor with 100 µF capacitance and a 10 V rated voltage. Designed as a general-purpose component within Nichicon’s UVR series, it targets compact consumer and entertainment electronics where small size and reliable smoothing or decoupling are required.

Key performance attributes include low leakage, measurable loss tangent at audio/low-frequency test conditions, defined ripple current capability at both low and high frequency, and an endurance specification of 2000 hours at 85°C—making it suitable for space-constrained low-voltage power circuits.

Key Features

• Capacitance & Voltage — 100 µF nominal capacitance with a rated voltage of 10 V and a tolerance of −20% to +20% (±20%).
• Small Radial Package — Compact radial can package with dimensions φ5 × 11 mm (L: 1.1 cm × D: 0.5 cm) and 2.0 mm lead spacing (±0.5 mm tolerance) for tight PCB layouts.
• Loss Tangent (tan δ) — tan δ = 0.24 measured at 20°C, 120 Hz, providing a quantified dissipation factor for circuit design and filtering considerations.
• Leakage Current — Low leakage current specified at 30 μA after rated voltage application at 20°C, useful for low-standby and precision circuits.
• Ripple Current Capability — Rated low-frequency ripple current of 145 mA at 120 Hz and high-frequency ripple current of 217.5 mA at 10 kHz to support smoothing and decoupling tasks across common switching and linear supply frequencies.
• Operating Range & Endurance — Operational temperature range −40°C to +85°C with an endurance rating of 2000 hours at 85°C, enabling predictable life performance in warm environments.
• Polarized Design — Polarized aluminum electrolytic suitable for DC smoothing and power rail decoupling.
• RoHS Compliant & Packaging Options — RoHS-compliant construction with bulk (no terminal forming) and bag packing options for flexible procurement and assembly handling.

Typical Applications

• Consumer & Entertainment Electronics — Local smoothing and decoupling in audio/video circuit boards where compact radial capacitors are required.
• Low-Voltage Power Supplies — Output filtering and bulk decoupling on 10 V rails in small power modules or reference supplies.
• Signal Conditioning & Analog Circuits — Decoupling and stabilization for analog front-ends where controlled leakage and defined tan δ aid predictable behavior.

Unique Advantages

• Compact footprint: φ5 × 11 mm can size supports dense board layouts and space-constrained designs without sacrificing capacitance.
• Measured loss and leakage specs: Specified tan δ and low leakage current provide designers with verifiable parameters for noise and standby current budgets.
• Broad ripple performance: Defined ripple current at both 120 Hz and 10 kHz allows selection with confidence for linear and switching supply applications.
• Endurance at elevated temperature: 2000 hours at 85°C gives a clear reliability baseline for thermal-stressed applications.
• Polarized radial format: Simple radial-lead mounting and standard lead spacing ease through-hole assembly and prototyping workflows.
