RNU1C101MCSASQ

The RNU1C101MCSASQ is a conductive polymer aluminum solid electrolytic capacitor in a radial lead can, designed for general-purpose electronic applications. It combines low ESR and high ripple-current capability with a compact φ6.3×10 mm package and a wide operating temperature range of −55°C to 105°C.

Engineered for robustness in through-hole designs, this device delivers long endurance (5,000 hours at 105°C), low leakage, and consistent performance across low- and high-frequency ripple conditions, making it suitable for designs that require reliable power-handling in a radial lead form factor.

Key Features

• Capacitance & Tolerance — 100 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C.
• Rated Voltage — 16 V rated voltage suitable for general-purpose power circuits.
• Low ESR — 25 mΩ equivalent series resistance measured at 20°C/100 kHz for improved AC performance.
• High Ripple Current Capability — Rated ripple currents of 282 mA at 120 Hz and 2.82 A at 300 kHz to support both low- and high-frequency applications.
• Low Leakage — Leakage current specified at 320 µA (after 2 minutes at rated voltage, 20°C).
• Long Endurance — 5,000 hours life rating at 105°C under rated voltage conditions.
• Wide Temperature Range — Operates from −55°C to +105°C for demanding ambient conditions.
• Radial Lead Package — φ6.3×10 mm can with 2.5 mm lead spacing (±0.5 mm), radial mounting for through-hole assemblies.
• Series-Level Attributes — RNU series characteristics include low ESR, high capacitance, high ripple current and compatibility with lead-free flow soldering conditions.
• RoHS Compliant & Production Ready — Conforms to RoHS requirements and available in bulk/bag packing; mass production status.

Typical Applications

• General-purpose electronics — Suited for circuits requiring compact, low-ESR energy storage and ripple handling.
• Through-hole power modules — Radial lead format and 2.5 mm lead spacing simplify mounting in through-hole power assemblies.
• High-frequency supply filtering — Rated ripple performance at 300 kHz supports filtering in higher-frequency power stages.

Unique Advantages

• Proven low ESR performance: 25 mΩ (20°C/100 kHz) provides reduced AC loss and improved ripple handling compared with higher-ESR capacitors.
• Dual-frequency ripple capability: Specified ripple ratings at both 120 Hz (282 mA) and 300 kHz (2.82 A) make selection straightforward across frequency domains.
• Robust thermal endurance: 5,000-hour life at 105°C supports long-term reliability in elevated-temperature environments.
• Compact radial package: φ6.3×10 mm can with 2.5 mm lead spacing delivers space-efficient through-hole mounting without sacrificing performance.
• Low leakage: 320 µA leakage at 20°C helps maintain efficiency in DC circuits and power rails.
• Regulatory compliance and production readiness: RoHS compliance, lead-free flow soldering compatibility at the series level, and bulk/bag packing streamline manufacturing and procurement.
