RNL1C122MDSASQ

The RNL1C122MDSASQ is a conductive polymer aluminum solid electrolytic capacitor in a radial-lead can designed for general-purpose electronic and power designs. It delivers high capacitance (1.2 mF) and low equivalent series resistance combined with broad temperature capability and multi‑kHz ripple handling for demanding decoupling and bulk energy-storage tasks.

Key Features

• Conductive polymer aluminum solid construction — Provides low ESR and reliable high-frequency behavior for power-decoupling and ripple applications.
• Capacitance and tolerance — 1200 μF with a tolerance of -20% to +20% measured at 120 Hz, 20°C, giving predictable charge storage for bulk filtering.
• Rated voltage — 16 V nominal rating for low-voltage power rails.
• Low ESR — 8 mΩ measured at 20°C/100 kHz, supporting low-loss operation at high switching frequencies.
• High ripple current capability — 750 mA at 120 Hz (low frequency) and 7.5 A at 300 kHz (high frequency), enabling effective smoothing in both low- and high-frequency power environments.
• Loss tangent (tan δ) — 0.12 specified at 20°C, 120 Hz to indicate dielectric loss characteristics under standard test conditions.
• Leakage current — 1920 μA (specified value), measured under the datasheet conditioning for consistent bias behavior.
• Lifetime and temperature range — Endurance rated for 5000 hours at 105°C and an operating range of -55°C to 105°C, supporting long-term operation in elevated-temperature environments.
• Radial lead package — φ8×20 mm can with 3.5 mm lead spacing (±0.5 mm) for through-hole assembly; available in bulk or bag packing.
• RoHS compliant — Conforms to RoHS directive requirements.

Typical Applications

• Power supply bulk filtering — High capacitance and low ESR reduce voltage ripple and provide energy reservoir for DC rails.
• Switching regulator output smoothing — High-frequency ripple capability (7.5 A at 300 kHz) and low ESR support fast-switching DC-DC converter outputs.
• DC link and decoupling in industrial and consumer electronics — Wide temperature range (−55°C to 105°C) and 5000 h endurance at 105°C suit sustained operation in robust systems.

Unique Advantages

• High ripple handling: With 7.5 A at high frequency and 750 mA at low frequency, the part manages both switching and line ripple effectively, reducing downstream noise.
• Low-loss operation: 8 mΩ ESR at 100 kHz minimizes dissipation and heating in high-current circuits, improving efficiency and thermal stability.
• Compact high-capacitance package: 1200 μF in an 8 × 20 mm can provides significant energy density for through-hole designs where space is constrained.
• Robust thermal endurance: Rated for 5000 hours at 105°C and a wide operating temperature range, supporting long-term reliability in elevated-temperature applications.
• Radial-lead convenience: Through-hole mounting with defined lead spacing simplifies prototyping and repairable assemblies.
• Regulatory readiness: RoHS compliance supports use in regulated product lines without additional material qualification.
