RNL1C242MDS1

The RNL1C242MDS1 is a conductive polymer aluminum solid electrolytic capacitor in a radial lead can designed for general-purpose electronic applications. It delivers high capacitance (2400 µF) at a 16 V rating with low ESR and high ripple-current capability in a compact φ10×20 mm package.

Engineered for robust performance across a wide temperature range (−55°C to +105°C) and an endurance rating of 2000 hours at 105°C, this RoHS-compliant component is suited for designs that require sustained high-ripple and low-loss energy storage in a through-hole radial form factor.

Key Features

• Capacitance and Tolerance — 2400 µF nominal capacitance with a tolerance of −20% to +20% for predictable bulk energy storage.
• Rated Voltage — 16 V rated voltage with appropriate surge margin for 16 V class power rails.
• Low ESR — ESR of 8 mΩ measured at 20°C/100 kHz, supporting low-loss operation and efficient high-frequency performance.
• High Ripple Current — Low-frequency ripple current of 810 mA (120 Hz) and high-frequency ripple capability of 8.1 A (300 kHz), enabling effective smoothing and decoupling under dynamic load conditions.
• Thermal and Lifetime Performance — Rated for operation from −55°C to +105°C with a load life of 2000 hours at 105°C.
• Package and Mounting — Radial lead, polarized can in a φ10×20 mm case with 5 mm lead spacing (±0.5 mm), supplied in bulk or bag packing (no terminal forming).
• Leakage Current — Specified leakage current of 3840 µA, useful for assessing standby and bias conditions.
• Regulatory — RoHS compliant.

Typical Applications

• General Purpose — Bulk energy storage and decoupling in circuits that require 2400 µF at 16 V with low ESR.
• High-Ripple Power Rails — Where elevated ripple-current capability (up to 8.1 A at high frequency) is needed for smoothing and transient handling.
• Harsh Temperature Environments — Designs that operate across −55°C to +105°C and require a capacitor with a rated endurance of 2000 hours at 105°C.

Unique Advantages

• High Capacitance in Compact Package — 2400 µF in a φ10×20 mm can reduces board area compared to multiple smaller capacitors.
• Low Loss at High Frequency — 8 mΩ ESR at 100 kHz minimizes heating and improves efficiency in high-frequency circuits.
• Robust Ripple Handling — Specified ripple currents at both low and high frequencies allow reliable operation under dynamic loads.
• Wide Temperature Range and Proven Lifetime — −55°C to +105°C rating with 2000 h endurance at 105°C supports reliability in demanding thermal conditions.
• Through-Hole Radial Form Factor — Simple integration into legacy and serviceable designs using standard radial mounting and 5 mm lead spacing.
• RoHS Compliance — Meets RoHS directive requirements for material compliance.
