RKS1K270MCNAJJGS

The RKS1K270MCNAJJGS is a surface-mount conductive-polymer aluminum electrolytic capacitor offering 27 µF capacitance at a rated voltage of 80 V. Designed for general-purpose power applications, it delivers low ESR and high ripple-current capability in a compact SMD radial-can package.

With an extended operating range from −55°C to 125°C and a rated load life of 3000 hours at 125°C, this part targets applications that require sustained performance under elevated temperature and ripple conditions.

Key Features

• Core Electrical Performance — 27 µF nominal capacitance with ±20% tolerance and tanδ 0.12 measured at 20°C, 120 Hz for predictable AC behavior.
• High Voltage Rating — 80 V rated voltage for higher-voltage rail applications.
• Low ESR and High Ripple Handling — ESR of 30 mΩ (20°C, 100 kHz) with low-frequency ripple current 140 mA (120 Hz) and high-frequency ripple current 1.4 A (300 kHz) to support decoupling and bulk filtering.
• Reliability & Endurance — Load life specified at 3000 hours at 125°C to meet demanding thermal endurance requirements.
• Wide Temperature Range — Rated from −55°C to 125°C for use across harsh thermal environments.
• SMD Radial Can Package — φ10 × 10 mm package (10 mm diameter × 10 mm length) in an SMD radial, can-style form factor for automated placement.
• Manufacturing & Packaging — Supplied in embossed carrier taping with moisture-proof packing; compatible with lead-free reflow (260°C peak).
• Leakage Current — Typical leakage current listed at 108 µA for predictable quiescent behavior.
• RoHS Compliance — Series-level compliance to RoHS directives as documented in the product series information.

Typical Applications

• Power supply filtering — Bulk and decoupling on higher-voltage rails up to 80 V, leveraging low ESR (30 mΩ) and 1.4 A high-frequency ripple capability for improved transient response.
• DC–DC converters — Energy-storage and output smoothing in converter stages where compact SMD can packages and high ripple tolerance are required.
• Industrial electronics — Filtering and decoupling in control and power modules operating across −55°C to 125°C with a 3000-hour endurance at elevated temperature.
• Commercial power equipment — General-purpose power conditioning in systems that benefit from a high-voltage 80 V rating and robust thermal endurance.

Unique Advantages

• High-voltage capability: 80 V rating enables use on elevated DC rails without series stacking.
• Low ESR for improved efficiency: 30 mΩ ESR at 100 kHz reduces conduction losses and supports higher-frequency ripple currents.
• High ripple acceptance: 1.4 A high-frequency ripple current rating supports demanding decoupling and power-conditioning tasks.
• Long high-temperature life: 3000 hours at 125°C provides predictable lifetime in thermally challenging designs.
• Compact SMD form factor: φ10 × 10 mm radial-can SMD package balances small footprint with high-voltage and ripple capability.
• Production-ready packaging: Embossed carrier taping with moisture-proof packing supports automated assembly and handling.
