RPS1C821MCN1GS

The RPS1C821MCN1GS is a surface-mount conductive polymer aluminum solid electrolytic capacitor from Nichicon's RPS series. It provides 820 µF capacitance at a 16 V rating in a compact φ10 × 12.4 mm SMD can, designed for general-purpose electronic power applications.

With low ESR and high ripple-current capability, wide operating temperature range (−55°C to 105°C) and a 2000 hour endurance rating at 105°C, this part targets designers who need stable decoupling and filtering performance in compact, automated assembly workflows.

Key Features

• Conductive Polymer Aluminum Electrolytic Solid electrolyte construction delivering stable capacitance and electrical characteristics for general-purpose power applications.
• Nominal Capacitance & Voltage 820 µF rated at 16 V with capacitance tolerance of ±20% (−20%~20%).
• Low ESR ESR of 18 mΩ measured at 20°C/100 kHz, enabling lower losses and improved high-frequency response.
• High Ripple Current Capability Low-frequency ripple: 420 mA at 120 Hz; high-frequency ripple: 4.2 A at 300 kHz, supporting demanding decoupling and filtering duties.
• Electrical Loss and Leakage tanδ (DF) 0.12 (20°C, 120 Hz) and leakage current 2624 µA (after 2 minutes at 20°C), providing defined electrical behaviour for design margining.
• Temperature Range & Endurance Operating −55°C to 105°C with a rated load life of 2000 hours at 105°C.
• SMD Packaging & Assembly φ10 × 12.4 mm SMD can supplied in embossed carrier taping with moisture-proof packing; SMD type supports lead-free reflow soldering to a 260°C peak as specified by the series.
• RoHS Compliant Conforms to RoHS requirements for environmental compliance.

Typical Applications

• Power supply decoupling and smoothing — Provides bulk capacitance and low impedance for voltage-rail stabilization in general-purpose electronic devices.
• DC–DC converter output filtering — Handles high-frequency ripple currents (up to 4.2 A at 300 kHz) for switching regulator outputs.
• Embedded and industrial electronics — Wide temperature range (−55°C to 105°C) and rated endurance at elevated temperature make it suitable for sustained operation in compact systems.

Unique Advantages

• High ripple current headroom: 4.2 A at 300 kHz and 420 mA at 120 Hz enable effective suppression of switching noise and ripple.
• Low high-frequency impedance: 18 mΩ ESR at 100 kHz supports improved transient response and reduced power dissipation.
• Durable thermal performance: −55°C to 105°C operating range with 2000 hours rated life at 105°C for predictable aging under heat stress.
• Compact SMD footprint: 820 µF in a φ10 × 12.4 mm can reduces board area compared with larger radial options while remaining surface-mount compatible.
• Production-ready packaging: Embossed carrier taping and moisture-proof packing streamline automated placement and handling.
• Standards-compliant: RoHS compliance for environmental regulatory requirements.
