RS80J331MDNASQ

The RS80J331MDNASQ from Nichicon is a conductive-polymer aluminum solid electrolytic capacitor in a low-profile radial-lead can. It delivers 330 µF at 6.3 V in a compact φ6.3 × 8 mm package, designed for general-purpose applications that require low ESR, high ripple-handling capability and extended high-temperature life.

This part targets compact power systems and board-level decoupling where low impedance, high-frequency performance and reliability over a wide temperature range (−55°C to 105°C) are important design criteria.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance at a rated voltage of 6.3 V with tolerance −20% to +20%.
• Low ESR & High-Frequency Performance — ESR of 8 mΩ measured at 20°C and 100 kHz, supporting high-frequency decoupling and power integrity.
• High Ripple Current Capability — Rated ripple current of 500 mA at 120 Hz (low frequency) and 5.0 A at 300 kHz (high frequency), enabling effective smoothing under varying switching conditions.
• Low Loss (tan δ) — tanδ (DF) of 0.1 measured at 20°C and 120 Hz for controlled dissipation in AC conditions.
• Extended Endurance — Load life of 5000 hours at 105°C, providing durability for high-temperature operating conditions.
• Compact, Radial-Lead Package — φ6.3 × 8 mm can with 2.5 mm lead spacing (±0.5 mm), radial-lead mounting for through-hole assembly and straightforward PCB layout.
• Polarized, General-Purpose Use — Designed as a polarized electrolytic capacitor for a wide range of board-level power applications.
• RoHS Compliant & Production Ready — RoHS status compliant and listed as mass production status; available in bulk or bag packaging (no terminal forming).

Typical Applications

• Power rail decoupling — Low ESR and high ripple current make this capacitor suitable for smoothing and stabilizing DC rails on compact PCBs.
• Switch-mode power supplies — Supports high-frequency ripple filtering in small-form-factor converters where space is limited.
• Embedded and consumer electronics — Compact φ6.3×8 mm package provides bulk capacitance and low impedance for board-level power conditioning.

Unique Advantages

• High ripple tolerance: 5.0 A at 300 kHz rating reduces thermal stress in high-frequency switching environments.
• Low impedance at high frequency: 8 mΩ ESR at 100 kHz helps maintain power integrity and reduces voltage ripple on fast switching nodes.
• Small footprint, high capacitance: 330 µF in a φ6.3 × 8 mm can enables designers to save PCB area without sacrificing bulk capacitance.
• Extended high-temperature life: 5000 hours at 105°C offers long-term reliability for applications exposed to elevated temperatures.
• Through-hole, radial-lead convenience: Simplifies assembly and replacement in designs that require through-hole components or hand-soldering.
