RL81C271MDN1

The RL81C271MDN1 is a conductive polymer aluminum solid electrolytic capacitor in a low-profile radial-lead can (φ8×8 mm). With 270 µF capacitance rated at 16 V, it combines very low ESR and high ripple-current capability for demanding power-decoupling and bulk-storage roles in compact assemblies.

Designed for general-purpose electronic equipment, this component delivers stable performance across a wide temperature range (−55 °C to 105 °C) and a specified load life of 2000 hours at 105 °C, making it suitable for designs that require compact energy storage with strong AC performance.

Key Features

• Conductive polymer dielectric — Solid electrolyte construction for low ESR and improved high-frequency performance compared with traditional electrolytics.
• Low ESR — ESR of 10 mΩ measured at 20 °C / 100 kHz, enabling efficient filtering and reduced heat generation under AC stress.
• High ripple-current capability — Rated ripple current of 500 mA at 120 Hz (low frequency) and 5 A at 300 kHz (high frequency) supports both low- and high-frequency power applications.
• Compact, low-profile package — φ8 × 8 mm can size with radial leads and 3.5 mm lead spacing (±0.5 mm) for space-constrained PCB layouts.
• Operational temperature and lifetime — Specified operating range of −55 °C to 105 °C with a rated life of 2000 hours at 105 °C for reliable long-term operation.
• Electrical characteristics — 270 µF capacitance with ±20% tolerance and tan δ (DF) of 0.12 measured at 20 °C, 120 Hz; leakage current listed at 864 µA after standard conditioning.
• Packaging and production status — Available in bulk (no terminal forming) or bag packing; product is in mass production and RoHS compliant.

Typical Applications

• General-purpose power filtering — Bulk and decoupling capacitor in electronic equipment where low ESR and high ripple-handling reduce voltage ripple and thermal stress.
• Switch-mode power supplies — Output-stage and post-regulation smoothing where high-frequency ripple current capability (5 A at 300 kHz) is required.
• Compact consumer and industrial electronics — Space-limited PCB designs that benefit from a φ8 × 8 mm low-profile can and radial-lead mounting.

Unique Advantages

• Superior AC performance: Low ESR (10 mΩ at 100 kHz) and high-frequency ripple rating deliver effective high-frequency noise suppression and reduced thermal losses.
• Space-efficient form factor: φ8 × 8 mm low-profile can and 3.5 mm lead spacing enable tighter board placement without sacrificing capacitance.
• Wide temperature tolerance: −55 °C to 105 °C rating allows use across a broad range of environmental conditions.
• Engineered for reliability: 2000-hour life at 105 °C provides predictable end-of-life behavior for design planning and longevity assessments.
• Production-ready and compliant: Mass-production availability and RoHS compliance simplify qualification and procurement for volume designs.
