RDS0G331MCNAFEGS

The RDS0G331MCNAFEGS is a conductive polymer aluminum solid electrolytic surface-mount capacitor offering high capacitance in a compact SMD can package. It is engineered for applications that require large capacitance, low ESR and stable performance across a wide temperature range up to 125°C.

Key value propositions include high ripple current capability, a long rated load life at elevated temperature, and lead‑free reflow compatibility for standard SMT assembly processes.

Key Features

• Core Electrical Performance — 330 µF rated capacitance at 4 V with ±20% tolerance; polarized device suitable for DC decoupling and energy storage functions.
• Low ESR & High Ripple Handling — ESR of 25 mΩ measured at 100 kHz and rated ripple current up to 1.05 A at 300 kHz (also 105 mA at 120 Hz), enabling improved filtering and transient handling in power circuits.
• Thermal and Endurance — Operating temperature range of −55 °C to +125 °C with a load life specified at 3000 hours at 125 °C for sustained high‑temperature operation.
• Package & Mounting — Surface mount radial can (SMD) sized L: 5.7 × D: 6.3 mm with recommended land size 6.5 × 6.5 mm for compact PCB layouts.
• Soldering Compatibility — Lead‑free reflow compatible with a 260 °C peak soldering profile for standard SMT assembly processes.
• Regulatory — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supply decoupling — Bulk and output decoupling on compact DC‑DC converters where high capacitance and low ESR improve voltage stability and transient response.
• Power management modules — Local energy storage in power rails for point‑of‑load regulators and power management ICs operating at elevated temperatures.
• Industrial electronics — Filtering and energy buffering in control and instrumentation equipment that must tolerate continuous operation up to 125 °C.

Unique Advantages

• High capacitance in a small SMD can — 330 µF in a 6.3 × 5.7 mm footprint enables reduced board area for high-capacitance requirements.
• Validated high-temperature endurance — Rated load life of 3000 hours at 125 °C provides quantifiable long‑term performance in hot environments.
• Strong ripple current capability — 1.05 A at 300 kHz and favorable frequency coefficients support demanding switching‑regulator ripple conditions.
• Low high‑frequency ESR — 25 mΩ at 100 kHz supports efficient filtering and minimizes losses in high‑frequency applications.
• Assembly-ready — Surface-mount can design with 260 °C peak lead‑free reflow compatibility simplifies integration into modern SMT production flows.
• RoHS compliant — Conforms to 2011/65/EU and (EU)2015/863 requirements for regulatory compliance.
