RSB0G331MCN1GS

The RSB0G331MCN1GS is a surface-mount conductive polymer aluminum solid electrolytic capacitor delivering 330 µF at a 4 V rating. It pairs high capacitance in a compact φ6.3 × 5.7 mm SMD can with characteristics intended for general-purpose electronic designs.

Designed for applications that require low equivalent series resistance (ESR), high ripple-current capability and robust thermal endurance, this RoHS‑compliant part provides measurable performance for power-conditioning and compact board-level designs.

Key Features

• Electrical Performance — 330 µF nominal capacitance with ±20% tolerance and a tanδ (DF) of 0.12 measured at 20°C, 120 Hz, providing predictable AC behavior.
• Low ESR — ESR of 11 mΩ measured at 20°C/100 kHz to minimize voltage drop and heat generation in high‑current paths.
• High Ripple Current Capability — Rated ripple current of 370 mA at 120 Hz (low frequency) and 3.7 A at 300 kHz (high frequency), supporting bulk decoupling and switching regulator loads.
• Leakage and Reliability — Leakage current specified at 700 µA and an endurance rating of 2000 hours at 105°C, providing stable long‑term operation under thermal stress.
• Wide Operating Temperature — Specified for −55°C to 105°C operation for use across a broad range of ambient conditions.
• Compact SMD Package & Packaging — φ6.3 × 5.7 mm radial, can‑style SMD package with embossed carrier taping and moisture‑proof packing for high-volume assembly; mass‑production status.

Typical Applications

• General‑purpose electronics — Surface‑mount applications that require a 4 V, 330 µF polymer aluminum capacitor for board‑level energy storage.
• Power supply filtering — Bulk decoupling and smoothing in low‑voltage power rails where low ESR and measurable ripple capability are important.
• High‑frequency power circuits — Circuits with switching frequencies up to the hundreds of kHz range benefit from the capacitor’s 3.7 A ripple‑current rating at 300 kHz.
• Space‑constrained SMD designs — Compact φ6.3 × 5.7 mm can‑style surface mount for dense board layouts and automated assembly.

Unique Advantages

• Low ESR for efficient power delivery: 11 mΩ ESR at 20°C/100 kHz reduces conduction losses and supports stable voltage at the load.
• High ripple‑current handling: 3.7 A capability at 300 kHz enables use with modern switching regulators and high‑frequency converters.
• Thermal endurance: Rated 2000 hours at 105°C, providing predictable life characteristics under elevated operating temperatures.
• Wide temperature range: −55°C to 105°C operation supports designs exposed to a broad span of ambient conditions.
• Assembly‑ready packaging: Supplied in embossed carrier taping with moisture‑proof packing for reel‑fed SMD assembly and high throughput production.
