RNU0G222MDN1

The RNU0G222MDN1 is a conductive polymer aluminum solid electrolytic capacitor in a radial‑lead can package, designed for general‑purpose electronic applications. It delivers high capacitance (2200 µF) at a low rated voltage (4 V) with a compact footprint (φ10 × 12.5 mm) and 5 mm lead spacing.

Engineered for power filtering and energy storage in board‑level designs, this component combines measurable low ESR and high ripple current capability with wide operating temperature range and defined endurance at elevated temperature.

Key Features

• Capacitance & Voltage — 2200 µF nominal capacitance with tolerance of −20% to +20% at a rated voltage of 4 V.
• Low ESR — ESR specified at 7 mΩ measured at 20°C / 100 kHz, supporting efficient power delivery and reduced dissipation.
• High Ripple Current — Rated ripple current of 610 mA at 120 Hz (low frequency) and 6.1 A at 300 kHz (high frequency), with frequency coefficients aligning to high‑frequency use cases.
• Leakage & Dissipation — Leakage current specified at 1760 µA (measured after 2 minutes at 20°C) and tanδ of 0.08 at 20°C / 120 Hz.
• Thermal & Lifetime — Operating temperature range −55°C to +105°C with an endurance rating of 2000 hours at 105°C and rated voltage.
• Package & Mounting — Radial lead (polarized) can, dimensions φ10 × 12.5 mm, lead spacing 5.0 mm (±0.5 mm), available in bulk or bag packing.
• Regulatory — RoHS compliant as indicated in product documentation.

Typical Applications

• Power supply filtering — Bulk decoupling and smoothing where high capacitance and low ESR improve voltage stability and transient response.
• DC‑DC converter output — Output filtering in converters that require high ripple current handling at switching frequencies.
• Embedded and industrial electronics — Board‑level energy storage and local decoupling in general‑purpose control and instrumentation circuits operating across wide temperature ranges.

Unique Advantages

• High capacitance in a compact can: 2200 µF in a φ10 × 12.5 mm package delivers significant bulk energy storage in a small through‑hole footprint.
• Measured low ESR for efficient performance: 7 mΩ (20°C/100 kHz) reduces conduction losses and supports tight voltage regulation.
• Robust ripple current capability: Rated for 610 mA at 120 Hz and 6.1 A at 300 kHz to handle both low‑ and high‑frequency ripple demands.
• Wide temperature tolerance and defined endurance: −55°C to +105°C operating range with 2000 hours endurance at 105°C for predictable life performance.
• Through‑hole radial lead form factor: Simplifies assembly for wave or hand soldering and offers reliable mechanical mounting for board‑level power sections.
• RoHS compliance: Meets environmental directive requirements as noted in product documentation.
