RSS1D390MCN1GS

The RSS1D390MCN1GS is a surface-mount conductive polymer aluminum solid electrolytic capacitor in Nichicon’s RSS series. It delivers 39 µF nominal capacitance at a 20 V rating in a compact φ6.3 × 5.7 mm can-style SMD package for general-purpose power applications.

Designed for high ripple environments and long-term operation, this part combines low ESR and high ripple-current capability with a wide operating temperature range and a 2000‑hour endurance at 105°C, making it suitable for compact board-level power filtering and decoupling tasks.

Key Features

• Capacitance & Voltage — 39 µF nominal capacitance with a rated voltage of 20 V and capacitance tolerance of −20% to +20%.
• Low ESR — ESR specified at 25 mΩ measured at 20°C / 100 kHz, supporting low-loss operation in high-frequency power paths.
• High Ripple Current — Rated ripple current of 280 mA at 120 Hz (low frequency) and 2.8 A at 300 kHz (high frequency), with frequency coefficients documented in the datasheet.
• Loss Angle (tan δ) — tan δ of 0.12 measured at 20°C, 120 Hz for predictable AC performance.
• Leakage Current — Specified leakage current of 156 µA (per datasheet measurement conditions).
• Reliability & Endurance — Load life rated 2000 hours at 105°C; performance limits for capacitance change, tan δ and ESR are defined after the endurance test.
• Temperature Range — Operating range from −55°C to +105°C for a broad set of ambient conditions.
• Compact SMD Package — Case size φ6.3 × 5.7 mm (L × D), surface-mount land recommendation 6.6 × 6.6 mm; package designed as a radial can — SMD.
• Assembly & Compliance — SMD type rated for lead-free reflow soldering with a 260°C peak, provided in embossed carrier taping with moisture-proof packing; RoHS compliant.

Typical Applications

• General-purpose power filtering — Bulk smoothing and decoupling on compact power rails where 39 µF at 20 V is required.
• High-frequency power paths — Low ESR and documented high-frequency ripple rating support filtering in switching regulator outputs and point-of-load stages.
• Compact SMD designs — Small φ6.3 × 5.7 mm can package for space-constrained board layouts that require radial-can SMD capacitors.

Unique Advantages

• Low-loss operation: 25 mΩ ESR at 100 kHz reduces power dissipation and heating in high-frequency applications.
• High ripple capability: 2.8 A rated ripple at 300 kHz enables reliable performance in switching power supplies and high-frequency decoupling.
• Thermal endurance: 2000 hours at 105°C provides predictable aging characteristics for designs exposed to elevated temperatures.
• Compact footprint: φ6.3 × 5.7 mm case and 6.6 × 6.6 mm recommended land allow high-density placement on modern PCBs.
• Manufacturing-ready packaging: Embossed carrier taping with moisture-proof packing supports automated placement and storage.
• Documented measurement conditions: ESR and tan δ specifications include measurement frequencies and temperatures (20°C / 100 kHz and 120 Hz), enabling direct comparison during design validation.

Why Choose RSS1D390MCN1GS?

RSS1D390MCN1GS balances compact SMD packaging with conductive-polymer aluminum capacitor performance: low ESR, high ripple-current handling, and a robust 2000‑hour life at 105°C. These attributes make it a strong candidate for board-level power decoupling and bulk filtering where space is limited but electrical performance and thermal endurance are required.

Its documented electrical parameters (ESR, tan δ, leakage current, ripple ratings) and lead-free reflow compatibility simplify validation and assembly for production designs, while RoHS compliance supports regulatory requirements.
