RFS1E270MCN1GS

The RFS1E270MCN1GS is a conductive polymer aluminum solid electrolytic capacitor in a compact surface-mount radial can package. It delivers 27 µF capacitance at 25 V with low ESR and high ripple current capability for general-purpose electronic designs.

Designed for compact SMD assemblies, the device combines low equivalent series resistance, high-frequency ripple handling and a wide operating temperature range to address demanding power decoupling and filtering requirements in space-constrained boards.

Key Features

• Dielectric / Core Conductive polymer aluminum solid electrolyte construction for stable performance and low ESR.
• Capacitance & Tolerance 27 µF nominal with ±20% tolerance (120 Hz, 20 °C).
• Rated Voltage 25 V DC rating suitable for common low-voltage power rails.
• Low ESR ESR = 40 mΩ measured at 20 °C / 100 kHz, supporting efficient high-frequency filtering.
• Ripple Current Low-frequency ripple current: 245 mA at 120 Hz; high-frequency ripple current: 2450 mA at 100 kHz (specified values).
• Leakage Current Leakage current specified at 135 µA (after standard conditioning).
• Reliability / Lifetime Load life endurance rated to 2000 hours at 105 °C.
• Temperature Range Operating from −55 °C to +105 °C.
• Package & Assembly Compact dimensions φ5 × 5.7 mm (L × D: 5.7 × 5 mm) in a radial can SMD package; supplied in embossed carrier taping with moisture-proof packing for automated assembly.
• Environmental RoHS compliant.

Typical Applications

• Power supply decoupling — Low ESR and specified high-frequency ripple current make it suitable for decoupling and smoothing on compact power rails.
• DC–DC converter output filtering — High ripple current capability and low ESR support output-stage filtering in switch-mode power supplies.
• Embedded and compact electronics — Small φ5×5.7 mm SMD radial can fits space-constrained board layouts requiring reliable capacitance at 25 V.

Unique Advantages

• Low ESR for tighter voltage stability: 40 mΩ (20 °C / 100 kHz) reduces AC impedance and supports cleaner power rails at high frequency.
• High ripple current handling: Specified ripple ratings (245 mA @120 Hz and 2450 mA @100 kHz) enable effective dissipation of AC stress in power applications.
• Compact SMD radial-can form factor: φ5×5.7 mm dimensions deliver high capacitance in a footprint optimized for automated surface-mount assembly.
• Wide operating temperature and proven endurance: −55 °C to +105 °C range with 2000 hours life at 105 °C supports reliable operation in elevated-temperature environments.
• RoHS compliance and production readiness: Environmentally compliant and available in embossed carrier taping / moisture-proof packing for volume assembly.
