RNS1D470MDN1

The RNS1D470MDN1 is a conductive polymer aluminum solid electrolytic capacitor in a radial‑lead can package, offering 47 µF capacitance at a 20 V rating. It is designed for general‑purpose electronic applications that require low equivalent series resistance and strong ripple handling in a compact radial form factor.

Key value comes from its low ESR (28 mΩ at 20°C/100 kHz), high-frequency ripple capability, and extended endurance (2000 hours at 105°C), making it suitable for designs that demand stable performance across temperature and frequency.

• Leakage and Reliability Leakage current specified at 141 µA (after 2 minutes at 20°C) and endurance rated 2000 hours at 105°C under rated voltage.
• Package & Mounting Radial lead, can package: case φ8 × 11.5 mm, lead spacing 3.5 mm ±0.5 mm, suitable for through‑hole mounting and straightforward PCB placement.
• Operating Range Wide operating temperature range from −55°C to +105°C for use across varied environmental conditions.
• Production & Packaging Available in bulk/bag packing and listed as mass production status.

Typical Applications

• Power supply filtering — Low ESR and specified ripple currents support smoothing and filtering in low‑voltage power rails.
• Switching regulators and DC–DC converters — High‑frequency ripple capability (3.4 A at 300 kHz) helps manage switching ripple on converter outputs.
• Embedded and industrial electronics — Endurance of 2000 hours at 105°C and −55°C to +105°C operating range make it suitable for stable operation in a variety of thermal environments.

Unique Advantages

• Low ESR for cleaner signals: 28 mΩ ESR at 20°C/100 kHz reduces voltage ripple and improves high‑frequency decoupling effectiveness.
• High ripple tolerance: Rated ripple currents at both low and high frequencies (340 mA at 120 Hz, 3.4 A at 300 kHz) accommodate demanding power conversion stages.
• Compact radial can: φ8 × 11.5 mm package with 3.5 mm lead spacing delivers a small footprint for through‑hole designs.
• Extended thermal endurance: 2000 hours at 105°C provides predictable lifetime performance under elevated temperature stress.
• Stable leakage behavior: Specified leakage current of 141 µA (measured after 2 minutes at 20°C) for reliable bias characteristics.
• Production ready: Mass production status and bulk/bag packing streamlines sourcing for volume designs.
