RDS0E501MCNAFEGS

The RDS0E501MCNAFEGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor delivering 500 µF at 2.5 V. It combines high capacitance and low ESR in a compact SMD radial-can package optimized for dense PCB power circuitry.

Designed for robust operation up to 125°C with a 3000 hour load life, this RoHS-compliant, lead-free reflow compatible component supports high ripple current handling and compact power-stage designs where thermal endurance and stable filtering are required.

Key Features

• Electrical performance — 500 µF nominal capacitance at 2.5 V with ±20% tolerance, providing substantial bulk storage for low‑voltage rails.
• Low ESR — 25 mΩ ESR specified at 100 kHz and 20°C, helping minimize power loss and thermal rise in high-current circuits.
• High ripple capability — Rated ripple specs include 105 mA at 120 Hz and 1.05 A at 300 kHz, supporting AC ripple and switching regulator loads.
• Thermal endurance — Load life of 3000 hours at 125°C under rated voltage; specified operating temperature range is −55°C to +125°C.
• SMD package & assembly — Radial can SMD package (φD×L: 6.3 × 5.7 mm) with surface-mount land size 6.5 × 6.5 mm; compatible with lead-free reflow peak temperature of 260°C.
• Leakage and reliability — Leakage current specification: after 2 minutes at rated voltage, not more than 0.3CV or 700 µA (whichever is greater), with endurance criteria limiting changes in capacitance, tan δ and ESR to within defined margins after life testing.
• Environmental compliance — Compliant with RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Compact power modules — Bulk decoupling and energy storage on low-voltage power rails where 500 µF at 2.5 V and low ESR reduce voltage ripple and board space.
• Switching regulator outputs — Handles high-frequency ripple currents (up to 1.05 A at 300 kHz) for DC–DC converters and point-of-load stages.
• Dense SMD assemblies — Radial can SMD format and 260°C lead-free reflow compatibility simplify placement in compact, automated surface-mount production flows.
• High-temperature environments — Specified operation to 125°C and 3000 hour load life for applications requiring sustained thermal reliability.

Unique Advantages

• High capacitance in a compact footprint: 500 µF in a 6.3 × 5.7 mm package enables significant bulk storage without large board area.
• Low ESR for improved efficiency: 25 mΩ at 100 kHz reduces conduction losses and heat generation in high-current circuits.
• Proven thermal endurance: 3000 hours at 125°C supports long-term operation in elevated temperature conditions.
• Broad ripple-frequency capability: Rated ripple current values at 120 Hz and 300 kHz cover both low-frequency smoothing and high-frequency switching applications.
• Manufacturing-friendly: Surface-mount radial-can design with 260°C peak lead-free reflow compatibility eases integration into automated SMT lines.
• Regulatory compliance: RoHS conformity for use in regulated assemblies.
