RNU0J122MCN1

The RNU0J122MCN1 from Nichicon is a conductive polymer aluminum solid electrolytic capacitor in a radial-lead can package. It provides 1200 µF capacitance at a 6.3 V rating with polarized terminals and is intended for general-purpose electronic applications.

Designed for demanding power-conditioning tasks, this part combines low equivalent series resistance and high ripple-current capability with a wide operating temperature range (−55 °C to 105 °C) and a rated lifetime of 2000 hours at 105 °C.

Key Features

• Capacitance & Tolerance — 1200 µF nominal capacitance with ±20% tolerance (measured at 120 Hz, 20 °C).
• Rated Voltage — 6.3 V DC rated voltage suitable for low-voltage power rails.
• Low ESR — ESR of 9 mΩ measured at 100 kHz and 20 °C, enabling lower loss and improved transient response.
• High Ripple Current — Rated ripple current up to 6.1 A at 300 kHz (and 610 mA at 120 Hz), supporting high-frequency power applications.
• Thermal & Lifetime Performance — Operating temperature range −55 °C to 105 °C with a load life specification of 2000 hours at 105 °C.
• Package & Mounting — Radial lead, can-style package with 3.5 mm lead spacing and compact dimensions (L: 1.15 × D: 0.8 cm).
• Environmental Compliance — RoHS compliant.

Typical Applications

• General-purpose power filtering — Low ESR and high ripple-current capability make it suitable for bulk smoothing and filtering on low-voltage rails.
• Decoupling and transient support — High capacitance and low ESR help stabilize supply lines and absorb switching transients.
• Board-level through-hole designs — Radial lead form factor simplifies placement in prototyping, repairable assemblies, and designs favoring through-hole components.

Unique Advantages

• Low-loss performance: 9 mΩ ESR at 100 kHz reduces power dissipation and improves efficiency in high-frequency circuits.
• High ripple tolerance: 6.1 A ripple capability at 300 kHz supports demanding switching-power environments.
• Thermally robust: Rated for −55 °C to 105 °C operation with a 2000-hour endurance at 105 °C for reliable performance under elevated temperatures.
• Compact radial-can packaging: Small footprint (1.15 × 0.8 cm) and 3.5 mm lead spacing enable dense board layouts while retaining through-hole mounting simplicity.
• Regulatory compliance: RoHS compliant to meet environmental requirements for modern assemblies.
