RHS0E821MCN1GS

The RHS0E821MCN1GS is a conductive polymer aluminum solid electrolytic surface-mount capacitor offering 820 µF at 2.5 V. It combines high capacitance with low equivalent series resistance (ESR) and high ripple-current capability for robust general-purpose SMD power designs.

Engineered for demanding operating conditions, the device supports an operating temperature range of –55°C to +105°C and a rated load life of 2000 hours at 105°C, and is compatible with lead-free reflow processes (260°C peak). The part is RoHS compliant.

Key Features

• Capacitance & Voltage — 820 µF rated capacitance at 2.5 V, with a tolerance of ±20% @ 120 Hz, 20°C.
• Low ESR — ESR specified at 9 mΩ measured at 100 kHz, 20°C, supporting low-loss operation in high-current circuits.
• High Ripple-Current Handling — High-frequency ripple capability of 5.4 A at 300 kHz (frequency coefficient 1.00 at 100 kHz and 300 kHz) and 540 mA at 120 Hz, enabling effective smoothing under fast-switching conditions.
• Endurance & Thermal Performance — Load life rated 2000 hours at 105°C; operating temperature range from –55°C to +105°C.
• Surface-Mount Package — Radial can SMD package (φ8 × L: 11.7 mm / L: 1.17 cm × D: 0.8 cm) designed for PCB land size L: 8.3 × W: 8.3 mm.
• Reflow & Environmental — SMD type compatible with lead-free reflow soldering conditions (260°C peak correspondence) and compliant with RoHS directives (2011/65/EU, (EU)2015/863).
• Polarized Construction — Polarized electrolytic design for DC applications where polarity is defined.

Typical Applications

• Power-supply filtering — Bulk and smoothing capacitance for low-voltage power rails where high capacitance and low ESR are required.
• High-frequency switching supplies — Supports high ripple currents at hundreds of kilohertz, suitable for decoupling in switching regulators and converters.
• General-purpose SMD designs — Surface-mount boards that require compact, high-capacitance solutions with lead-free reflow compatibility and extended thermal endurance.

Unique Advantages

• High effective stored charge: 820 µF provides substantial bulk capacitance in a compact SMD radial can, reducing the need for multiple discrete capacitors.
• Low power loss under ripple: 9 mΩ ESR at 100 kHz minimizes I²R losses and thermal rise in high-current AC environments.
• Proven high-frequency performance: Rated ripple current of 5.4 A at 300 kHz (frequency coefficient 1.00) enables reliable operation with fast-switching power stages.
• Robust thermal endurance: 2000 hours at 105°C rated life supports long-term stability in elevated-temperature applications.
• Assembly-ready SMD form factor: Lead-free reflow compatibility (260°C peak) simplifies automated PCB assembly while meeting RoHS requirements.
