RKS1H330MCNAHJGS

The RKS1H330MCNAHJGS is a conductive polymer aluminum solid electrolytic surface‑mount capacitor designed for general‑purpose electronic applications that require high capacitance in a compact SMD can. It combines low LC and low ESR with high allowable ripple current to support power decoupling and high‑frequency smoothing in demanding assemblies.

Key differentiators include a 33 µF capacitance at 50 V, an ESR of 30 mΩ measured at 100 kHz/20 °C, and an extended operating temperature range from −55 °C to 125 °C with a rated load life of 3000 hours at 125 °C.

Key Features

• Dielectric / Core Conductive polymer aluminum solid electrolytic capacitor delivering stable capacitance and low loss (tan δ = 0.12 at 20 °C, 120 Hz).
• Capacitance & Voltage 33 µF nominal capacitance with a rated voltage of 50 V and tolerance of −20% to +20%.
• Low ESR & High‑Frequency Performance ESR specified at 30 mΩ (20 °C, 100 kHz) and high‑frequency ripple handling of 1.25 A at 300 kHz, enabling effective high‑frequency decoupling.
• Ripple Current Capability Low‑frequency ripple current 125 mA at 120 Hz and high‑frequency ripple current 1.25 A at 300 kHz for robust power filtering.
• Reliability & Endurance Rated life of 3000 hours at 125 °C and leakage current limited to 100 µA, supporting long‑term thermal and electrical endurance.
• Package & Assembly SMD radial can (φ8 × 10 mm) supplied in embossed carrier taping with moisture‑proof packing; compatible with reflow soldering conditions specified by the manufacturer.
• Environmental RoHS‑compliant construction.

Typical Applications

• Power supply decoupling Low ESR and high ripple current rating make this part suitable for smoothing and decoupling in DC‑DC converters and board‑level power rails.
• High‑frequency filtering Specified ESR at 100 kHz and high‑frequency ripple capability support HF noise suppression and output filtering for switching regulators.
• General purpose industrial electronics Extended temperature range (−55 °C to 125 °C) and long load life enable use in industrial control and embedded systems operating across wide temperature extremes.

Unique Advantages

• High ripple tolerance: 1.25 A at 300 kHz and 125 mA at 120 Hz provide margin for demanding power‑rail conditions.
• Low ESR at high frequency: 30 mΩ at 100 kHz reduces power loss and improves transient response in high‑speed circuits.
• Thermal endurance: Rated for 3000 hours at 125 °C, offering long‑term reliability in high‑temperature environments.
• Compact SMD can package: φ8 × 10 mm radial SMD can allows integration into space‑constrained board designs while supporting automated assembly via embossed carrier taping.
• Controlled leakage: Leakage current specified at 100 µA helps maintain predictable behavior in power management applications.
• RoHS‑compliant: Meets RoHS environmental requirements for regulated markets.
