RHS1E101MCN1GS

The RHS1E101MCN1GS from Nichicon is a surface-mount conductive polymer aluminum solid electrolytic capacitor in the RHS series. It delivers 100 µF capacitance at a 25 V rating in a compact φ8 × 8.7 mm can, designed for general-purpose SMD power applications.

With low ESR and high ripple-current capability across a wide −55 °C to 105 °C operating range and a 2000-hour endurance at 105 °C, the part targets designs that require reliable decoupling, bulk smoothing and high-frequency ripple handling in compact surface-mount form factors.

Key Features

• Dielectric / Construction Conductive polymer aluminum solid electrolyte in an SMD radial can construction for polarized applications.
• Capacitance & Tolerance 100 µF capacitance with a tolerance of −20% to +20% (measured at 20 °C, 120 Hz).
• Low ESR ESR = 18 mΩ measured at 20 °C / 100 kHz, helping minimize voltage drop and power dissipation at high frequency.
• High Ripple-Current Capability Low-frequency ripple current 400 mA (120 Hz) and high-frequency ripple current 4.0 A (300 kHz) for demanding power-filtering tasks.
• Leakage Current Specified leakage current up to 700 µA (measured at 20 °C after 2 minutes at rated voltage).
• Temperature & Endurance Operating temperature range −55 °C to 105 °C with a rated life/endurance of 2000 hours at 105 °C.
• Package & Mounting Compact φ8 × 8.7 mm package (L × D: 8.7 × 8 mm) for surface-mount assembly; supplied in embossed carrier taping with moisture-proof packing for automated placement.
• Regulatory RoHS compliant.

Typical Applications

• Power supply filtering: Use for bulk smoothing and decoupling where low ESR and high ripple-current capability reduce voltage ripple and thermal stress.
• Switch-mode power supplies (SMPS): Supports high-frequency ripple handling thanks to 4.0 A ripple-current rating at 300 kHz and low ESR at 100 kHz.
• Compact SMD power modules: Small φ8 footprint and surface-mount can construction enable integration into space-constrained board layouts.

Unique Advantages

• Low power loss: 18 mΩ ESR at 20 °C / 100 kHz reduces I2R losses and helps maintain efficiency in high-frequency circuits.
• High ripple tolerance: 4.0 A ripple current capability at high frequency supports demanding decoupling and filtering needs in switching applications.
• Wide operating range: −55 °C to 105 °C operation and a 2000-hour rated life at 105 °C provide durability in thermally challenging environments.
• Compact SMD form factor: φ8 × 8.7 mm can allows higher capacitance density in surface-mount designs while supporting automated assembly (embossed carrier taping).
• Predictable leakage behavior: Leakage current specified at 700 µA (20 °C after 2 minutes) for predictable standby and bias characteristics.
• RoHS compliant: Meets environmental requirements for modern electronics production.
