RSA1D151MCN1GS

The RSA1D151MCN1GS is a surface-mount conductive polymer aluminum solid electrolytic capacitor offering 150 µF capacitance at a 20 V rating. It combines low ESR, high ripple-current capability and a compact radial can SMD package to address general-purpose electronic power filtering and decoupling requirements.

Designed for reliable operation from −55 °C to +105 °C with a rated load life of 2000 hours at 105 °C, this part supports designs that require sustained performance under elevated temperature and high-frequency ripple conditions.

Key Features

• Capacitance and Voltage — 150 µF nominal capacitance with a rated voltage of 20 V and tolerance ±20% (120 Hz, 20 °C).
• Low ESR and High-Frequency Performance — ESR of 25 mΩ measured at 20 °C / 100 kHz, enabling lower loss and improved performance at high switching frequencies.
• High Ripple Current Capability — Low-frequency ripple current 320 mA at 120 Hz and high-frequency ripple current 3.2 A at 300 kHz, with frequency coefficients that support full-rated ripple up to high kHz ranges.
• Dielectric Loss — tan δ (loss tangent) of 0.12 measured at 20 °C, 120 Hz, indicating stable dissipation characteristics for AC conditions.
• Reliability and Endurance — Rated for 2000 hours at 105 °C (endurance condition), with leakage current specified at 600 µA after 2 minutes at rated voltage and 20 °C.
• Compact SMD Package — φ6.3 × 7.7 mm can (radial, SMD) with recommended land size 6.5 × 6.5 mm; packaged in embossed carrier taping with moisture-proof packing for automated assembly.
• Polarized, Surface-Mount — Designed for polarized applications in surface-mount assemblies; compatible with lead‑free reflow soldering conditions (260 °C peak as noted for the series).
• Regulatory — RoHS compliant.

Typical Applications

• General-purpose power management — Bulk decoupling and smoothing in power rails where 150 µF at 20 V with low ESR and high ripple handling is required.
• Compact SMD power modules — Surface-mount radial can fits dense board layouts that require high-capacitance SMD components with automated placement and tape-and-reel handling.
• High-frequency switching supplies — Low ESR (25 mΩ at 100 kHz) and high-frequency ripple rating (3.2 A at 300 kHz) for switching regulator output filtering and decoupling in high-speed systems.
• Elevated-temperature environments — Specified operation to +105 °C with a 2000-hour endurance rating for sustained performance under thermal stress.

Unique Advantages

• Low ESR for reduced losses: 25 mΩ ESR at 100 kHz minimizes power dissipation and supports efficient high-frequency operation.
• High ripple capacity across frequencies: Rated ripple current of 3.2 A at 300 kHz and a frequency coefficient that preserves ripple capability at high kHz enables use with modern switching topologies.
• Compact SMD form factor: φ6.3 × 7.7 mm can with 6.5 × 6.5 mm land footprint optimizes board area while providing 150 µF capacitance.
• Proven high-temperature endurance: 2000 hours at 105 °C gives predictable lifetime behavior for thermally demanding applications.
• Manufacturing-ready packaging: Embossed carrier taping and moisture-proof packing support high-volume, automated assembly processes.
• Regulatory compliance: RoHS-compliant construction for use in regulated production environments.
