RHS1A331MCN1GS

The RHS1A331MCN1GS from Nichicon is a surface-mount, conductive polymer aluminum solid electrolytic capacitor with 330 µF capacitance and a 10 V rated voltage. Engineered for general-purpose power applications, it combines high capacitance with low ESR to support board-level bulk decoupling and ripple current handling in compact SMD formats.

Designed as part of the RHS series, this φ8 × 7.7 mm radial SMD can delivers measurable performance—including a 19 mΩ ESR (20°C / 100 kHz), 3.39 A high-frequency ripple capability, and a −55°C to 105°C operating range—while shipping in embossed carrier taping with moisture-proof packing for production use.

Key Features

• Capacitance & Tolerance — 330 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C, suitable for bulk energy storage and decoupling in low-voltage designs.
• Rated Voltage — 10 V DC rated voltage, supporting low-voltage power rails and DC–DC converter outputs.
• Low ESR — 19 mΩ ESR measured at 20°C / 100 kHz, minimizing voltage drop under AC loading and improving converter stability.
• High Ripple Current Capability — Rated ripple current up to 339 mA at 120 Hz and 3.39 A at 300 kHz, delivering robust performance across low and high-frequency power domains.
• Temperature & Endurance — Wide operating range from −55°C to 105°C and a rated life of 2000 hours at 105°C, suitable for sustained thermal stress conditions within that rating.
• Packaging & Mounting — Surface-mount (radial can SMD) package, φ8 × 7.7 mm size, supplied in embossed carrier taping with moisture-proof packing for automated assembly.
• Leakage & Loss — Leakage current specified at 660 µA (measured after 2 minutes at 20°C) and tan δ of 0.12 (20°C, 120 Hz), for predictable loss and leakage behavior in circuit designs.
• RoHS Compliant — Manufactured in compliance with RoHS requirements.

Typical Applications

• Power Supply Filtering — Bulk decoupling and smoothing on low-voltage rails where 330 µF at 10 V and low ESR reduce output ripple and improve regulator stability.
• DC–DC Converter Output — Output-side filtering for switching regulators where high-frequency ripple current capability (up to 3.39 A at 300 kHz) is required.
• Point-of-Load Energy Storage — Local energy reservoir for transient load support on compact boards, leveraging high capacitance in an SMD can package.

Unique Advantages

• Compact high-capacity SMD form — 330 µF in a φ8 × 7.7 mm package enables significant bulk capacitance in space-constrained assemblies.
• Predictable high-frequency performance — 19 mΩ ESR at 100 kHz and a 3.39 A ripple rating at 300 kHz deliver measurable AC performance for switching applications.
• Extended temperature tolerance — −55°C to 105°C operating range and a 2000 hour life at 105°C support sustained operation in thermally demanding environments within the specified limits.
• Production-ready packaging — Supplied in embossed carrier taping with moisture-proof packing to support automated placement and standard handling.
• Measured leakage and loss parameters — Specified leakage current (660 µA) and tan δ (0.12 at 120 Hz, 20°C) help designers budget standby loss and leakage in power budgets.
