RNU1A100MDSASQ

The RNU1A100MDSASQ from Nichicon is a conductive polymer aluminum solid electrolytic capacitor in a radial-lead, polarized package. It delivers a compact 10 µF capacitance at 10 V with a focus on low ESR and high ripple-current capability for general-purpose electronic designs.

Designed for board-level through-hole applications, this radial-can capacitor provides extended endurance at elevated temperatures and is supplied in bulk or bag packing for flexible assembly workflows.

Key Features

• Capacitance & Voltage — 10 µF rated capacitance at 10 V with tolerance -20% to +20% (±20%).
• Conductive Polymer Construction — Solid polymer electrolyte for low ESR and stable performance.
• Low ESR — ESR of 220 mΩ measured at 20°C/100 kHz, supporting improved high-frequency performance.
• High Ripple Current — Rated ripple current of 70 mA at 120 Hz (low frequency) and 700 mA at 300 kHz (high frequency) for demanding AC conditions.
• Dissipation Factor — tanδ = 0.12 measured at 20°C, 120 Hz, 10 V for predictable loss characteristics.
• Endurance — Life rating of 5000 hours at 105°C under rated voltage conditions.
• Temperature Range — Operational range from -55°C to +105°C.
• Compact Radial Package — Case size φ4 × 5 mm with 1.5 mm lead spacing (±0.5 mm), ideal for tight board layouts.
• Mounting & Polarity — Radial lead, polarized component suitable for through-hole mounting.
• RoHS Compliant & Production Status — RoHS compliant and in mass production; available in bulk (no terminal forming) or bag packing.

Typical Applications

• General-purpose electronics — Ideal where a compact 10 µF, 10 V polarized capacitor with low ESR is required for board-level circuitry.
• Power decoupling and smoothing — Low ESR and rated ripple currents make this capacitor suitable for local supply smoothing and decoupling in DC circuits.
• High-frequency board-level circuits — Solid polymer construction and ESR measured at 100 kHz support stable performance in high-frequency applications.

Unique Advantages

• Low-loss polymer electrolyte: Delivers lower ESR and predictable tanδ (0.12 at 20°C/120 Hz) for efficient high-frequency operation.
• High ripple handling: Rated ripple current values of 70 mA (120 Hz) and 700 mA (300 kHz) enable reliable operation under AC ripple loads.
• Compact footprint: Small φ4×5 mm can and 1.5 mm lead spacing reduce board space while enabling through-hole assembly.
• Extended high-temperature life: 5000-hour endurance at 105°C supports long-term reliability in elevated-temperature environments.
• Flexible supply formats: Available in bulk (no terminal forming) or bag packing to match production and prototyping workflows.
• Regulatory compliance: RoHS compliant for use in markets requiring restricted substance compliance.
