RNL1E102MDS4

The RNL1E102MDS4 is a conductive polymer aluminum solid electrolytic capacitor in a radial-lead can designed for general-purpose power applications. It delivers 1000 µF capacitance at 25 V with low ESR and high ripple-current capability in a compact φ10 × 16 mm package.

Engineered for robust thermal performance, the RNL1E102MDS4 operates from −55 °C to +105 °C and carries a rated endurance of 2000 hours at 105 °C, offering stable capacitance, controlled loss tangent, and predictable leakage for power filtering and decoupling tasks.

Key Features

• Capacitance & Voltage — 1000 µF nominal capacitance at a rated voltage of 25 V with tolerance −20% to +20%.
• Low ESR and Loss Tangent — ESR of 10 mΩ at 20 °C/100 kHz and tanδ of 0.12 (20 °C, 120 Hz) for reduced voltage drop and heat under AC loading.
• High Ripple Current — Low-frequency ripple current 580 mA (120 Hz) and high-frequency ripple current 5.8 A (300 kHz), supporting both bulk smoothing and high‑frequency switching environments.
• Reliability & Lifetime — Rated life/endurance of 2000 hours at 105 °C with defined limits for capacitance change, tanδ, ESR and leakage after the test period.
• Temperature Range — Wide operating temperature from −55 °C to +105 °C for demanding thermal conditions.
• Package & Mounting — Radial lead can, size φ10 × 16 mm with 5.0 mm lead spacing (±0.5 mm); available in bulk (no terminal forming) or bag packing.
• Leakage Current — Specified leakage current of 2500 µA (measured after 2 minutes at 20 °C), supporting predictable DC performance.
• RoHS Compliant — Conforms to RoHS requirements for environmental compliance.

Typical Applications

• Power supply bulk filtering — Use as bulk capacitors on DC rails where 1000 µF and low ESR reduce ripple and stabilize output voltages.
• Switching regulator output decoupling — High-frequency ripple current capability (5.8 A at 300 kHz) supports outputs of high-speed DC‑DC converters.
• Industrial control electronics — Wide temperature range (−55 °C to +105 °C) and 2000‑hour endurance at 105 °C help maintain performance in demanding environments.
• Consumer and general-purpose electronics — Compact φ10 × 16 mm radial package for space-efficient power smoothing and energy storage.

Unique Advantages

• High ripple tolerance: 5.8 A at high frequency and 580 mA at 120 Hz allow the capacitor to handle both HF switching noise and lower-frequency ripple without excessive heating.
• Low dissipation under AC load: 10 mΩ ESR at 100 kHz and tanδ 0.12 reduce losses, improving efficiency and thermal margin in power stages.
• Compact, through-hole form factor: φ10 × 16 mm radial can with 5 mm lead spacing provides a small-footprint solution for PCB power rails requiring higher capacitance.
• Thermal durability: Rated for −55 °C to +105 °C and tested for 2000 hours at 105 °C, giving predictable aging characteristics in elevated-temperature applications.
• Predictable leakage performance: Leakage current specified at 2500 µA (20 °C after 2 minutes) for consistent DC bias behavior and margining in power designs.
• RoHS compliant: Environmentally compliant materials simplify regulatory considerations for commercial and industrial products.
