RNS1E330MDN1

The RNS1E330MDN1 is a conductive polymer aluminum solid electrolytic capacitor in a radial lead can, offering 33 µF capacitance at a 25 V rating. Designed for general-purpose electronic use, it provides low equivalent series resistance and strong ripple-current capability in a compact φ10×12.5 mm package.

Its core value proposition is reliable power-handling in through-hole designs: low ESR (20 mΩ at 20°C/100 kHz), high-frequency ripple capability (3.8 A at 300 kHz), and a wide operating temperature range of −55 °C to 105 °C with a 2000-hour endurance at 105 °C.

Key Features

• Core Electrical — 33 µF capacitance with ±20% tolerance at 120 Hz, 20 °C, and a 25 V rated voltage for general-purpose power decoupling and smoothing.
• Low ESR and High Ripple Handling — ESR specified at 20 mΩ (20 °C/100 kHz) with rated ripple currents of 380 mA at 120 Hz and 3.8 A at 300 kHz, enabling efficient high-frequency filtering and bulk decoupling.
• Temperature and Endurance — Operates across −55 °C to 105 °C with an endurance rating of 2000 hours at 105 °C under rated voltage, supporting sustained use in demanding thermal environments.
• Leakage and Loss Characteristics — Specified leakage current of 165 µA and tanδ measured conditions noted at 20 °C, 120 Hz to support predictable loss behavior.
• Package and Mounting — Radial lead, can-style package sized φ10×12.5 mm with 5.0 mm lead spacing (±0.5 mm), supplied in bulk or bag packing for through-hole assembly.
• Production Status — Part is in mass production, suitable for volume deployments.

Typical Applications

• General Purpose Electronics — Useful where a compact through-hole capacitor with low ESR and solid ripple performance is required for power filtering and decoupling.
• Power Supply Modules — Applicable in power rails that require high-frequency ripple handling and stable capacitance over a wide temperature range.
• Industrial Equipment — Suitable for general-purpose use in industrial designs that demand endurance at elevated temperatures.

Unique Advantages

• Low ESR for Improved Efficiency: 20 mΩ ESR at 20 °C/100 kHz reduces I²R losses and improves high-frequency performance compared to higher-ESR electrolytics.
• High-Frequency Ripple Capacity: Rated ripple current of 3.8 A at 300 kHz supports demanding switching and high-frequency power systems.
• Wide Operating Temperature: −55 °C to 105 °C range ensures consistent behavior across harsh environmental conditions.
• Solid Electrolyte Reliability: Conductive polymer construction with a 2000-hour life at 105 °C provides stable capacitance and ESR over endurance testing.
• Through-Hole Form Factor: Radial lead, φ10×12.5 mm can with 5.0 mm lead spacing simplifies placement in legacy or mechanically robust PCB designs.
• Production-Ready: Mass production availability and standard packaging options (bulk/bag) support procurement for volume assemblies.
