RPS1C390MCN1GS

The RPS1C390MCN1GS is a conductive polymer aluminum solid electrolytic capacitor in a surface-mount radial can package. It delivers 39 µF nominal capacitance at 16 V with a -20% to +20% tolerance and is intended for general-purpose electronic designs that require low ESR and elevated ripple handling in a compact SMD form factor.

Designed for demanding ambient conditions, this part supports an operating temperature range from -55°C to 105°C and a rated life of 2000 hours at 105°C, providing a balance of power performance and reliability for board-level power delivery and filtering tasks.

Key Features

• Core Electricals — 39 µF capacitance at 16 V rated voltage with tolerance of -20% to +20% and tanδ (DF) = 0.1 measured at 20°C, 120 Hz.
• Low ESR — ESR specified at 45 mΩ (measured at 20°C/100 kHz), supporting efficient high-frequency performance and reduced internal dissipation.
• High Ripple Capability — Rated ripple currents of 200 mA at 120 Hz and 2 A at 300 kHz (high-frequency rating), with series frequency coefficients that support full-rated ripple at 100 kHz–300 kHz.
• Leakage and Endurance — Leakage current of 124 µA (measured per product specification) and load life of 2000 hours at 105°C under rated voltage.
• Thermal Range — Wide operating temperature range from -55°C to 105°C suitable for a broad set of industrial and consumer environments.
• Compact SMD Package & Assembly — Case size φ6.3 × 5.7 mm with recommended surface-mount land size 6.6 × 6.6 mm; supplied in embossed carrier taping with moisture-proof packing for automated placement. Series SMD types are compatible with lead-free reflow peak of 260°C per datasheet guidance.
• Regulatory — RoHS compliant.

Typical Applications

• Power modules and DC–DC converters — Provides bulk smoothing and high-frequency ripple handling where low ESR (45 mΩ) and 2 A ripple capability at 300 kHz are required.
• Point-of-load filtering — Compact φ6.3×5.7 mm package supports board-level decoupling and filtering in tight layouts while meeting the specified capacitance and tolerance.
• Industrial and consumer electronics — Wide -55°C to 105°C temperature range and 2000-hour life at 105°C make the device suitable for assemblies exposed to elevated temperatures and continuous operation.

Unique Advantages

• High-frequency performance: Low ESR at 100 kHz (45 mΩ) and full-frequency ripple coefficients enable effective operation in switching regulator environments.
• Compact footprint: φ6.3 × 5.7 mm SMD can saves board area while delivering 39 µF of capacitance for space-constrained designs.
• Robust thermal endurance: Specified for -55°C to 105°C operation and 2000 hours at 105°C, helping maintain capacitance and ESR stability in elevated temperatures.
• Production-ready packaging: Supplied in embossed carrier taping with moisture-proof packing to support automated pick-and-place and reflow processes.
• Measured leakage and loss characteristics: Defined leakage current (124 µA) and tanδ (0.1 at 120 Hz) provide predictable performance for precision power designs.
