RNL1E122MDSASQ

The RNL1E122MDSASQ is a conductive polymer aluminum solid electrolytic capacitor in a radial-lead can, rated 25 V with 1200 µF capacitance and ±20% tolerance. Designed for general-purpose electronic use, it delivers low ESR and high ripple-current capability in a compact φ10 × 20 mm package.

Key value propositions include low equivalent series resistance (10 mΩ @ 20°C/100 kHz), high-frequency ripple handling (up to 8.1 A at 300 kHz), and long endurance (5,000 hours at 105°C), making it suitable where efficient power smoothing and reliable long-term operation are required.

Key Features

• Capacitance & Voltage — 1.2 mF (1200 µF) nominal capacitance at a rated voltage of 25 V with tolerance of -20% to +20%.
• Low ESR — 10 mΩ measured at 20°C and 100 kHz, supporting low-loss operation in high-frequency power circuits.
• High Ripple Current — Rated low-frequency ripple current of 810 mA at 120 Hz and high-frequency ripple capability of 8.1 A at 300 kHz, enabling effective smoothing in switching supplies.
• Loss Tangent — tanδ of 0.12 measured at 20°C/120 Hz, suitable for stable AC performance assessments.
• Endurance & Temperature Range — Load life 5000 hours at 105°C and operating range from -55°C to 105°C for robust thermal reliability.
• Package & Mounting — Radial lead can, size φ10 × 20 mm with 5 mm lead spacing (±0.5 mm) and bulk/bag packing options for board-level assembly flexibility.
• Polarized, RoHS Compliant — Polarized aluminum polymer construction and RoHS compliance as stated.

Typical Applications

• Power supply filtering — Bulk smoothing and decoupling in switching and linear power supplies where low ESR and high ripple current are required.
• DC-DC converter output — Output-stage filtering for converters that demand high-frequency ripple handling and compact energy storage.
• General-purpose electronics — Board-level bulk capacitance and stabilization in consumer and industrial equipment labeled as general purpose.

Unique Advantages

• High ripple-current capability: 8.1 A at 300 kHz and 810 mA at 120 Hz let designers reduce capacitor count or size while meeting ripple requirements.
• Low high-frequency loss: 10 mΩ ESR at 100 kHz minimizes power dissipation in high-speed switching environments.
• Thermal endurance: 5,000 hours at 105°C provides predictable aging and long-term performance in elevated-temperature applications.
• Compact radial form factor: φ10 × 20 mm can size with 5 mm lead spacing simplifies through-hole placement and mechanical retention on PCBs.
• Stable AC characteristics: tanδ = 0.12 (20°C/120 Hz) supports consistent behavior in AC and ripple conditions used for design verification.
