RDS0E821MCNAHFGS

The RDS0E821MCNAHFGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor from Nichicon’s RDS series. It provides high capacitance (820 µF) and is designed for applications that require substantial ripple-handling and compact SMD packaging.

Key value propositions include high ripple-current capability and extended high-temperature endurance — a load life of 3000 hours at 125°C — combined with lead-free reflow compatibility (260°C peak) and RoHS compliance. These characteristics make it suited to compact power systems and decoupling tasks where space, thermal resilience, and electrical performance matter.

Key Features

• Electrical Performance — 820 µF capacitance rated at 2.5 V with ±20% tolerance; polarized device suitable for bulk energy storage and rail decoupling.
• Low ESR — Equivalent series resistance of 18 mΩ measured at 100 kHz (20°C), enabling lower loss and better high-frequency behavior in switching power circuits.
• High Ripple-Current Capability — Rated ripple current of 205 mA at 120 Hz and 2.05 A at 300 kHz, supporting both low- and high-frequency switching environments.
• Thermal Endurance — Operates from −55°C to +125°C with a rated load life of 3000 hours at 125°C under rated voltage; endurance criteria include capacitance within ±20% and ESR/tan δ within specified limits after test.
• Package & Mounting — Surface-mount radial can (SMD) in an 8 × 6.7 mm case (L: 6.7 × D: 8 mm) with recommended land size 8.3 × 8.3 mm; compatible with lead-free reflow soldering at a 260°C peak.
• Leakage Current Specification — After 2 minutes at rated voltage, leakage current is not more than 0.3CV or 700 µA, whichever is greater, per the product endurance conditioning.
• Regulatory Compliance — Compliant with RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supply decoupling — Bulk and intermediate decoupling for point-of-load converters where high capacitance and low ESR stabilize voltage rails.
• DC–DC converters and power modules — Handles high ripple currents encountered in switching power stages, improving ripple filtering and thermal resilience.
• Compact embedded power systems — Small SMD can (8 × 6.7 mm) enables high-capacitance energy storage in space-constrained designs.
• Equipment operating at elevated temperatures — Suited for electronics exposed to higher ambient or internal temperatures thanks to a −55°C to +125°C operating range and 3000-hour endurance at 125°C.

Unique Advantages

• High capacitance in a compact SMD footprint: 820 µF packed into an 8 × 6.7 mm case for area-efficient power design.
• Low ESR for improved efficiency: 18 mΩ (100 kHz) reduces I²R losses and supports stable operation under ripple stress.
• Robust ripple handling: Rated for 2.05 A at 300 kHz to accommodate high-frequency switching currents.
• Extended high-temperature life: 3000 hours at 125°C offers predictable long-term performance in hot environments.
• Manufacturing-ready SMD package: Lead-free reflow compatibility (260°C peak) for modern SMT assembly processes.
• Regulatory alignment: RoHS compliance for environmental and materials requirements.
