RKS1C121MCNAHFGS

The RKS1C121MCNAHFGS is a surface-mount conductive polymer aluminum electrolytic capacitor offering 120 µF capacitance at a 16 V rating. Designed for general-purpose electronic applications, it delivers low ESR and high allowable ripple current in a compact φ8 × 6.7 mm radial can SMD package.

Key value propositions include low equivalent series resistance (30 mΩ at 100 kHz), high-frequency ripple handling (1.6 A at 300 kHz), and long-term endurance (3000 hours at 125°C), making it suitable for demanding power decoupling and bulk filtering tasks in temperature-challenging environments.

Key Features

• Capacitance & Voltage: 120 µF nominal capacitance with a rated voltage of 16 V and capacitance tolerance of −20% to +20% (measured at 20°C, 120 Hz).
• Low ESR: 30 mΩ equivalent series resistance specified at 20°C and 100 kHz, supporting reduced power loss and improved high-frequency performance.
• High Ripple Current Capability: Rated low-frequency ripple current of 160 mA (120 Hz) and high-frequency ripple current of 1.6 A (300 kHz), enabling effective smoothing under AC ripple stress.
• Thermal Endurance: Load life of 3000 hours at 125°C under rated voltage, with an operating temperature range from −55°C to +125°C.
• Leakage & Loss Characteristics: Leakage current specified at 100 µA and tangent of loss angle (tan δ) of 0.12 (20°C, 120 Hz), providing predictable loss and leakage behavior.
• Assembly & Packaging: φ8 × 6.7 mm SMD radial can package supplied in embossed carrier taping with moisture-proof packing for automated placement and handling.
• Compliance: RoHS‑compliant construction.

Typical Applications

• Power supply decoupling and bulk filtering: Low ESR and high ripple current capability make this capacitor suitable for smoothing supply rails and reducing voltage ripple.
• DC–DC converter output filtering: Compact SMD radial can and high-frequency ripple handling support use on converter outputs where space and thermal performance matter.
• General-purpose electronics: Rated for −55°C to +125°C and a long 3000‑hour life at 125°C, it is appropriate for a wide range of industrial and commercial board-level power applications.

Unique Advantages

• High ripple tolerance: The combination of 1.6 A high-frequency ripple rating and 160 mA low-frequency ripple rating helps maintain stable performance under AC stress.
• Low power loss at high frequency: 30 mΩ ESR at 100 kHz reduces heat generation and improves efficiency in high-frequency circuits.
• Extended high-temperature life: 3000 hours endurance at 125°C provides a predictable lifetime for designs exposed to elevated operating temperatures.
• Compact SMD radial package: φ8 × 6.7 mm size in embossed carrier taping enables automated assembly while saving board area compared with larger through-hole cans.
• Measured and specified electrical stability: Clear specifications for tan δ (0.12 at 20°C/120 Hz) and leakage current (100 µA) aid design margining and verification.
• RoHS compliance: Material compliance supports use in regulated manufacturing environments.
