RS81C331MDN1

The RS81C331MDN1 is a conductive polymer aluminum solid electrolytic capacitor in a radial-lead, low-profile can (φ6.3 × 8 mm). It provides 330 µF capacitance at a 16 V rated voltage with polarized mounting and is offered in a bulk/bag packaging option.

Designed for general-purpose electronics, this Nichicon RS8-series part combines low ESR/ESL characteristics with a compact footprint and high ripple current capability for space-constrained power and decoupling applications that require reliable operation across a wide temperature range.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a rated voltage of 16 V and a capacitance tolerance of −20% to +20%.
• Low ESR / High-frequency performance — ESR specified at 12 mΩ (20°C / 100 kHz), supporting low-loss operation at high switching frequencies.
• High ripple current — Rated ripple current of 468 mA at 120 Hz (low frequency) and 4.68 A at 300 kHz (high frequency), enabling effective smoothing under dynamic loads.
• Low-profile radial package — Compact dimensions φ6.3 × 8 mm with radial lead mounting and a 2.5 mm lead spacing (±0.5 mm tolerance) for through-hole assemblies and tight board layouts.
• Endurance & temperature range — Load life rated at 2000 hours at 105°C and continuous operating temperature range from −55°C to 105°C.
• Leakage and dissipation — Specified leakage current 1584 µA and tangent of loss angle (tan δ) 0.1 measured at 20°C, 120 Hz.
• Compliance — RoHS compliant.
• Packaging — Supplied in bulk (no terminal forming) / bag packing for volume assembly workflows.

Typical Applications

• General-purpose electronics — Suitable for a broad range of designs that require polarized bulk capacitance in compact, through-hole packages.
• Power decoupling and smoothing — Low ESR and substantial ripple current ratings support filtering and smoothing in DC/DC converters and power rails.
• Compact, low-profile modules — Small φ6.3 × 8 mm footprint and radial leads make the part a fit for space-constrained power assemblies and board-level modules.

Unique Advantages

• Low ESR at high frequency — 12 mΩ ESR (20°C / 100 kHz) reduces conduction losses and improves transient response in switching environments.
• High ripple current handling — Rated for both low-frequency and high-frequency ripple currents (468 mA at 120 Hz; 4.68 A at 300 kHz), enabling reliable operation under dynamic load conditions.
• Compact low-profile form factor — φ6.3 × 8 mm can height supports designs with limited vertical space while preserving capacitance.
• Wide operating temperature and defined life — −55°C to 105°C range with a 2000-hour endurance rating at 105°C provides predictable behavior in elevated-temperature environments.
• Through-hole mounting convenience — Radial lead configuration with 2.5 mm lead spacing (±0.5 mm) simplifies PCB placement for hand- or wave-soldered assemblies.
• Regulatory compliance — RoHS compliance supports deployment in regions and products requiring restricted-substance adherence.

Why Choose RS81C331MDN1?

The RS81C331MDN1 balances compact, low-profile packaging with electrical characteristics targeted at reliable power conditioning: low ESR, defined high-frequency ripple capability, and a 2000-hour life at 105°C. Its radial-lead can and 2.5 mm lead spacing make it straightforward to integrate into through-hole assemblies where board space is limited.

This Nichicon RS8-series capacitor is suited to designers and procurement teams seeking a verified, general-purpose conductive polymer aluminum solution for decoupling, smoothing, and other polarized capacitance needs across a wide temperature range, with RoHS compliance for regulated markets.
