RNU1V820MCNASQ

The RNU1V820MCNASQ is a conductive polymer aluminum solid electrolytic capacitor in a radial-lead can, offering 82 µF capacitance at a 35 V rating. It is designed for general-purpose applications that demand low ESR, high ripple-current capability and high capacitance in a compact radial package.

With a wide operating temperature range and a long endurance specification, this radial-lead capacitor is intended for power-handling roles where reduced losses and stable performance over time are required.

Key Features

• Capacitance & Tolerance — 82 µF nominal capacitance with tolerance of −20% to +20% at 120 Hz, 20 °C.
• Rated Voltage — 35 V DC rated voltage for a range of mid-voltage power applications.
• Low ESR — ESR of 20 mΩ measured at 20 °C / 100 kHz to minimize series losses in high-frequency circuits.
• High Ripple Current — Low-frequency ripple current 400 mA (120 Hz) and high-frequency ripple current 4.0 A (300 kHz) to support demanding power filtering and decoupling tasks.
• Electrical Losses — tan δ (DF) 0.12 measured at 20 °C / 120 Hz for predictable dissipation characteristics.
• Leakage Current — Specified leakage current 574 µA (measured after 2 minutes at 20 °C), enabling designers to budget off-state losses.
• Reliability & Life — Endurance rated for 5000 hours at 105 °C, providing long-term stability under elevated-temperature stress.
• Package & Mounting — Radial lead can, size φ8 × 11.5 mm (0.8 × 1.15 cm), lead spacing 3.5 mm ±0.5 mm; available as bulk (no terminal forming) or bag packing.
• Environmental Compliance — RoHS compliant.

Typical Applications

• General-purpose power systems — Suited for power filtering and energy smoothing where low ESR and high ripple-current handling are required.
• High-frequency decoupling — Low ESR at 100 kHz and high HF ripple current capacity support decoupling in high-frequency power stages.
• Industrial and commercial electronics — Designed for general-purpose circuits that demand extended endurance at elevated temperature (5000 h at 105 °C).

Unique Advantages

• Low series resistance: 20 mΩ ESR at 100 kHz reduces conduction losses and heat generation in high-frequency applications.
• High ripple capability: Rated for 4.0 A at 300 kHz and 400 mA at 120 Hz, enabling robust handling of AC stress on power rails.
• Extended thermal endurance: 5000-hour life rating at 105 °C supports reliable long-term operation in thermally demanding environments.
• Compact radial package: φ8 × 11.5 mm can with 3.5 mm lead spacing offers a space-efficient solution for through-hole assemblies.
• Predictable leakage and dissipation: Specified leakage current (574 µA) and tan δ (0.12 at 120 Hz) allow accurate thermal and power-loss budgeting.
• RoHS compliant: Meets RoHS directive requirements for restricted substances.
