RNU1V151MDN1

The RNU1V151MDN1 from Nichicon is a radial-lead conductive polymer aluminum solid electrolytic capacitor in the RNU series. It provides 150 µF capacitance at a 35 V rating in a compact φ10 × 12.5 mm can with 5 mm lead spacing, designed for general-purpose electronic applications.

Its low ESR, high rated ripple current capacity and wide operating temperature range (−55°C to 105°C) make it suitable where efficient power decoupling and high-frequency ripple handling are required. This part is RoHS compliant and is in mass production.

Key Features

• Capacitance & Voltage — 150 µF rated capacitance with a 35 V working voltage and ±20% tolerance (−20%~20%).
• Low ESR — ESR of 20 mΩ measured at 20°C / 100 kHz, reducing loss and heat under high-frequency conditions.
• High Ripple Current — Rated ripple current of 380 mA at 120 Hz and 3.8 A at 300 kHz, supporting both low- and high-frequency ripple demands.
• Thermal and Endurance Performance — Rated for operation from −55°C to 105°C with a specified life/endurance of 2000 hours at 105°C.
• Leakage & Dissipation — Specified leakage current of 1050 µA and tan δ (DF) of 0.12 measured at 20°C, 120 Hz.
• Package & Mounting — Radial lead can (φ10×12.5 L) with 5.0 mm lead spacing (±0.5 mm); available in bulk (no terminal forming) or bag packing.
• Regulatory Compliance — RoHS compliant.

Typical Applications

• Power supply decoupling — Compact 150 µF capacitance with low ESR supports decoupling on 35 V rails to stabilize supply voltage and reduce noise.
• High-frequency ripple smoothing — Rated ripple current up to 3.8 A at 300 kHz and 20 mΩ ESR enable effective smoothing in circuits with elevated switching frequencies.
• General-purpose electronic designs — Suited for general-purpose circuits requiring polarized electrolytic capacitors with robust temperature and endurance characteristics.

Unique Advantages

• Compact radial can — φ10 × 12.5 mm package with 5 mm lead spacing minimizes board area while providing 150 µF capacitance.
• Low dissipation under AC conditions — 20 mΩ ESR at 100 kHz helps reduce power loss and self-heating in high-frequency applications.
• High ripple handling — Supports both low-frequency (380 mA at 120 Hz) and high-frequency (3.8 A at 300 kHz) ripple currents for versatile power-management use.
• Wide temperature range and rated endurance — −55°C to 105°C operating range and 2000 h life at 105°C provide predictable long-term performance in demanding environments.
• Series pedigree — Part of the RNU series, which emphasizes low ESR and high ripple capability in conductive polymer aluminum electrolytic capacitors.
