RHS0J821MCN1GS

The RHS0J821MCN1GS is a surface-mount conductive polymer aluminum solid electrolytic capacitor designed for general-purpose electronic applications requiring high capacitance in a compact SMD package. It combines low equivalent series resistance (ESR), high ripple-current capability and a long load life to support demanding power and decoupling functions.

Key value propositions include high capacitance (820 µF) at 6.3 V, low ESR for improved high-frequency performance, and proven endurance at elevated temperature (load life specified at 105°C). The part is compatible with lead-free reflow soldering and is RoHS compliant.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with a rated voltage of 6.3 V and tolerance of ±20% (−20% to +20%).
• Low ESR — 10 mΩ equivalent series resistance measured at 100 kHz, 20°C, reducing power loss and improving high-frequency response.
• High Ripple Current — Rated ripple current of 515 mA at 120 Hz and 5.15 A at 300 kHz, supporting circuits with significant AC stress.
• Temperature & Endurance — Operating temperature range from −55°C to +105°C and load-life endurance indicated at 2000 / 5000 hours at 105°C (endurance test condition).
• Surface-Mount Package — Radial can SMD package with body dimensions L: 1.17 × D: 0.8 cm and recommended land pattern of 8.3 × 8.3 mm for compact PCB integration.
• Assembly & Compliance — Lead-free reflow soldering compatible (260°C peak) and compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose power smoothing — Bulk capacitance for smoothing and energy storage where high capacitance in an SMD form factor is required.
• High-ripple circuits — Circuits subject to substantial ripple current benefit from the part's specified ripple ratings at both low and high frequencies.
• Compact SMD designs — Applications needing a high-capacitance, low-ESR solution in a small board footprint and standard surface-mount land pattern.

Unique Advantages

• Reduced voltage fluctuation under load: High nominal capacitance (820 µF) helps stabilize supply rails and absorb transient energy.
• Improved high-frequency performance: Low ESR (10 mΩ at 100 kHz) minimizes losses and supports better transient response.
• Handles significant AC stress: High rated ripple current (5.15 A at 300 kHz) allows use in power stages and high-frequency environments.
• Durable at elevated temperature: Endurance specified at 105°C (2000 / 5000 hours) provides predictable life characteristics in hot operating conditions.
• Lead‑free manufacturing compatible: Designed for lead-free reflow (260°C peak), simplifying assembly in modern production flows.
• RoHS compliant: Meets RoHS directive requirements for restricted substances.
