RDS0E501MCNAHFGS

The Nichicon RDS0E501MCNAHFGS is a conductive polymer aluminum solid electrolytic capacitor in the RDS series, supplied in a surface-mount radial can (SMD) package. It offers high capacitance and high ripple-current capability in a compact footprint, with a rated voltage of 2.5 V and a rated capacitance of 500 µF.

Engineered for elevated-temperature environments, this part delivers a load life of 3000 hours at 125°C and is compatible with lead-free reflow processes up to a 260°C peak. Its combination of low ESR and high ripple handling makes it suitable for demanding power applications where space and thermal endurance are important.

Key Features

• Construction: Conductive polymer aluminum solid electrolytic capacitor—high capacitance in a polymer-based solid electrolyte.
• Capacitance & Voltage: 500 µF rated capacitance with a rated voltage of 2.5 V and tolerance of ±20% at 120 Hz, 20°C.
• High-temperature endurance: Rated operating temperature range −55°C to +125°C with a specified load life of 3000 hours at 125°C.
• Low ESR: 18 mΩ measured at 100 kHz, 20°C, supporting efficient high-frequency operation and reduced losses.
• High ripple capability: Rated ripple currents up to 2.05 A at higher frequency operation (300 kHz) and 205 mA at 120 Hz, enabling use in high-ripple circuits.
• SMD package & reflow-ready: Surface-mount radial can (8 × 6.7 mm case size, L: 6.7 × D: 8 mm) with lead-free reflow compatibility at a 260°C peak.
• Leakage current: Specified leakage behavior consistent with series ratings (≤700 µA after 2 minutes at 20°C for 2.5 V category parts as specified in the series data).
• Regulatory status: Compliant with RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supply filtering and decoupling: Low ESR and high capacitance make it suitable for smoothing outputs and decoupling at the board level in thermally demanding installations.
• High-ripple power stages: Rated ripple current up to 2.05 A at high frequency supports DC–DC converters and power modules that generate significant AC stress on capacitors.
• Compact SMD power designs: Small 8 × 6.7 mm case and surface-mount form factor allow integration where board space is restricted but high capacitance is required.

Unique Advantages

• Extended high-temperature life: 3000 hours at 125°C offers predictable endurance for designs exposed to sustained elevated temperatures.
• Efficient high-frequency performance: 18 mΩ ESR at 100 kHz reduces losses and supports stable operation in high-frequency circuits.
• Strong ripple handling: High rated ripple current across frequencies reduces the risk of overheating and extends system reliability in power conversion stages.
• Surface-mount integration: SMD radial-can package and lead-free reflow compatibility simplify automated assembly and reduce process risk for lead-free manufacturing.
• Regulatory compliance: RoHS conformity supports deployment in regions and products where restricted substances compliance is required.
