RNU1V820MDNASQ

The RNU1V820MDNASQ is a conductive polymer aluminum solid electrolytic capacitor in a radial lead can designed for general-purpose electronic equipment. It combines low ESR and high ripple-current capability in a compact φ8×11.5 mm package, making it suitable for power filtering and high-frequency power circuits.

Key value propositions include low equivalent series resistance (20 mΩ at 100 kHz), high ripple handling (400 mA at 120 Hz and 4 A at 300 kHz), extended endurance (5,000 hours at 105°C), and a wide operating temperature range of −55°C to +105°C.

Key Features

• Capacitance & Voltage — 82 µF rated capacitance at 35 V with capacitance tolerance of −20% to +20%.
• Low ESR — ESR specified at 20 mΩ (20°C / 100 kHz) for improved high-frequency performance and reduced loss.
• High Ripple Current — Rated ripple current of 400 mA at 120 Hz and 4 A at 300 kHz for demanding ripple-load conditions.
• Tangent of Loss Angle (tan δ) — tanδ measured at 0.12 (20°C, 120 Hz), indicating defined dielectric loss under standard conditions.
• Long Endurance — Load life specified as 5,000 hours at 105°C, supporting sustained operation in elevated-temperature environments.
• Wide Temperature Range — Operates from −55°C to +105°C for use across a broad set of environmental conditions.
• Radial Lead Package — φ8×11.5 mm can with 3.5 mm lead spacing (±0.5 mm), available in bulk (no terminal forming) or bag packing for manual assembly or through-hole production.
• Leakage Current — Specified leakage current of 574 µA (measured after 2 minutes at 20°C), useful for design budgeting.
• RoHS Compliant — Conforms to RoHS requirements.

Typical Applications

• General-Purpose Electronics — Bulk decoupling and smoothing in boards where reliable capacitance and long life are required.
• High-Frequency Power Circuits — Low ESR and 4 A ripple capability at 300 kHz support high-frequency switching supplies and point-of-load stages.
• Industrial Electronics — Wide −55°C to +105°C operating range and 5,000-hour endurance at 105°C address demanding environmental and duty-cycle conditions.

Unique Advantages

• Low-loss performance: 20 mΩ ESR at 100 kHz and tanδ of 0.12 (20°C, 120 Hz) reduce thermal dissipation and improve efficiency in power circuits.
• High ripple tolerance: Rated ripple currents of 400 mA (120 Hz) and 4 A (300 kHz) allow handling of both low- and high-frequency ripple content.
• Compact radial form factor: φ8×11.5 mm can with standard 3.5 mm lead spacing provides a small footprint for through-hole designs.
• Extended high-temperature life: 5,000 hours at 105°C supports reliable long-term operation under elevated-temperature stress.
• Design-ready specifications: Clear, measured values for leakage current (574 µA), ESR, tanδ, and ripple current enable accurate BOM and thermal planning.
• RoHS compliant: Conforms to RoHS requirements for regulatory alignment in end products.
