RKS1E820MCNAJLGS

The RKS1E820MCNAJLGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor designed for general-purpose electronic power applications. It combines high capacitance (82 µF) with low equivalent series resistance and elevated temperature endurance for reliable smoothing and decoupling in compact SMD assemblies.

Key value comes from its low ESR and high allowable ripple current, a broad operating temperature range (−55 °C to 125 °C), and a rated load life of 3000 hours at 125 °C—attributes that support durable performance in demanding environments.

Key Features

• Core Technology Conductive polymer aluminum solid electrolyte construction for stable performance and lower ESR compared with traditional electrolytics.
• Capacitance & Voltage 82 µF nominal capacitance at a 25 V rated voltage with capacitance tolerance of −20% to +20% (measured at 20 °C, 120 Hz).
• Low ESR & High Ripple Handling ESR of 20 mΩ measured at 20 °C / 100 kHz and high-frequency ripple current rating of 2.0 A (specified at 300 kHz), enabling effective filtering and transient handling.
• Dissipation Factor & Leakage tan δ of 0.12 (measured at 20 °C, 120 Hz) and leakage current specified at 102 µA, providing predictable loss and standby characteristics.
• Endurance & Temperature Range Rated life of 3000 hours at 125 °C and an operating temperature range from −55 °C to 125 °C for sustained performance in elevated-temperature applications.
• SMD Package & Handling Radial can SMD package sized φ10 × 12.4 mm (D × L), supplied in embossed carrier taping with moisture-proof packing for automated assembly and storage.
• RoHS Compliance Compliant with RoHS requirements, supporting environmental and regulatory preferences.

Typical Applications

• Power rail decoupling — Use on local power rails to smooth voltage and absorb transient currents where 82 µF and low ESR reduce ripple and maintain rail stability.
• DC–DC converter output filtering — Effective at filtering high-frequency switching components thanks to a 20 mΩ ESR at 100 kHz and a 2.0 A high-frequency ripple rating.
• Embedded and industrial electronics — Suited for general-purpose power conditioning in compact SMD assemblies operating across a wide temperature range (−55 °C to 125 °C).

Unique Advantages

• High ripple capability: 2.0 A high-frequency ripple rating minimizes voltage excursion in switching applications and supports tighter regulation.
• Low loss at high frequency: 20 mΩ ESR at 100 kHz and tan δ of 0.12 at 120 Hz reduce heat generation and improve efficiency in high-speed circuits.
• Extended high-temperature life: 3000 hours rated life at 125 °C provides predictable aging and endurance for thermally stressed designs.
• Compact SMD form factor: φ10 × 12.4 mm package fits tight board layouts while enabling automated placement from embossed carrier tape.
• Controlled leakage: Specified leakage current of 102 µA supports predictable standby and hold-up behavior in power circuits.
• Regulatory alignment: RoHS compliance supports environmental and manufacturing requirements.
