RR50E821MDN1

The RR50E821MDN1 is a conductive polymer aluminum solid electrolytic capacitor in a radial-lead can designed for general-purpose electronic designs. It delivers ultra-low ESR and high ripple-current capability in a compact φ8×11.5 mm package, making it suitable for power-dense and temperature-demanding applications.

Built for reliability, this part is rated for 2.5 V and 820 µF with a wide operating temperature range of −55°C to 105°C and a 2000 hour endurance at 105°C, offering measurable performance and predictable long-term behavior in embedded and industrial systems.

Key Features

• Capacitance and Voltage: 820 µF nominal capacitance with ±20% tolerance at a rated voltage of 2.5 V, suitable for bulk decoupling and energy storage in low-voltage power rails.
• Ultra-low ESR & High ripple current: ESR of 5 mΩ measured at 20°C/100 kHz and rated ripple current of 6.63 A at 300 kHz (663 mA at 120 Hz), enabling efficient high-frequency filtering and reduced self-heating.
• Temperature and Endurance: Operating range −55°C to 105°C with a rated load life of 2000 hours at 105°C, providing stable performance under elevated temperature stress.
• Leakage Current: Specified leakage current of 512 µA (after 2 minutes at 20°C), allowing predictable standby and steady-state loss calculations.
• Radial lead package: φ8×11.5 mm aluminum can with 3.5 mm lead spacing (±0.5 mm), available in bulk (no terminal forming) or bag packing for straightforward through-hole assembly.
• Regulatory compliance: RoHS compliant—suitable for designs requiring restricted-substances compliance.

Typical Applications

• Power supply filtering: Ultra-low ESR and high ripple-current capability support smoothing and filtering on low-voltage DC rails.
• DC–DC converters and regulators: Compact high-capacitance radial package helps stabilize converters and supply rails where space is constrained.
• Industrial and embedded electronics: Wide −55°C to 105°C operating range and 2000 h endurance at 105°C provide durability for temperature-stressed environments.

Unique Advantages

• Reduced thermal stress: Low ESR (5 mΩ) minimizes I²R losses and internal heating under ripple load, improving reliability.
• High AC performance: Rated ripple current up to 6.63 A at 300 kHz supports demanding high-frequency decoupling tasks.
• Compact footprint: φ8×11.5 mm can offers high capacitance in a small radial package for space-sensitive boards.
• Predictable lifetime: 2000 hours at 105°C with defined post-test limits on capacitance, tan δ and ESR for confident end-of-life assessment.
• Easy through-hole assembly: Radial leads with 3.5 mm spacing and bag/bulk packing simplify handling and PCB insertion processes.
