RPS1H390MCN1GS

The RPS1H390MCN1GS is a surface-mount conductive polymer aluminum solid electrolytic capacitor in Nichicon’s RPS series, offering 39 µF capacitance at a 50 V rating. It is designed for general-purpose electronics that require low equivalent series resistance and robust ripple-current handling in a compact radial can SMD package (φ8×11.7 mm).

Key value comes from its combination of low ESR, high-frequency ripple capability and elevated-temperature endurance: ESR is specified at 26 mΩ (20 °C/100 kHz), rated ripple current up to 2.3 A at high frequency, and a rated lifetime of 2000 hours at 105 °C.

Key Features

• Capacitance & Tolerance — 39 µF nominal capacitance with tolerance of −20% to +20% (measured at 120 Hz, 20 °C).
• Voltage Rating — 50 V rated voltage suitable for higher-voltage general-purpose applications within the RPS series range.
• Low ESR — ESR specified at 26 mΩ (20 °C/100 kHz), supporting efficient power delivery and reduced losses at high frequency.
• High Ripple-Current Capability — Rated ripple current of 230 mA at 120 Hz and 2.3 A at 300 kHz; frequency coefficients indicate full-rated capability at 100 kHz and 300 kHz.
• Leakage Current — Specified leakage current of 390 µA (after 2 minutes at 20 °C and rated voltage), for predictable bias behavior.
• Endurance & Temperature Range — Life rating of 2000 hours at 105 °C and operating temperature range of −55 °C to +105 °C for elevated-temperature reliability.
• Compact SMD Packaging — Radial can SMD package, size φ8×11.7 mm, with recommended surface-mount land size of 8.3×8.3 mm; supplied in embossed carrier taping with moisture-proof packing.
• Assembly Compatibility — Series supports lead-free reflow soldering with a 260 °C peak reflow condition, per RPS series specification.
• Regulatory — RoHS compliant.

Typical Applications

• General-purpose electronics — Bulk and decoupling applications where low ESR and predictable leakage are required across a −55 °C to +105 °C operating range.
• High-frequency power circuits — Circuits that require sustained ripple-current handling at 100–300 kHz frequencies, leveraging the 2.3 A rated ripple at 300 kHz and ESR rating.
• Compact SMD systems — Designs needing a compact radial can SMD capacitor (φ8×11.7 mm) with embossed carrier taping for automated assembly.

Unique Advantages

• Low ESR for efficient performance: 26 mΩ ESR at 20 °C/100 kHz reduces loss and improves voltage stability under high-frequency conditions.
• High-frequency ripple capability: Rated ripple current up to 2.3 A at 300 kHz supports demanding switching power stages and high-speed power systems.
• Wide temperature endurance: −55 °C to +105 °C operating range with a 2000 hour life rating at 105 °C provides predictable behavior in elevated-temperature environments.
• Assembly-ready SMD form factor: φ8×11.7 mm radial can with embossed carrier taping and moisture-proof packing enables automated surface-mount production and handling.
• Measured leakage and loss characteristics: Specified leakage current (390 µA) and tan δ (0.15 at 20 °C/120 Hz) help ensure stable analog and power performance.
• RoHS compliant and lead-free reflow capable: Meets environmental requirements and is compatible with 260 °C peak lead-free reflow processing.
