RSS0J331MCN1GS

The RSS0J331MCN1GS is a conductive polymer aluminum solid electrolytic capacitor in a compact surface-mount can (φ6.3×5.7 mm). It delivers high capacitance and low ESR in a small footprint, making it suitable for power decoupling and smoothing in space-constrained electronic designs.

Designed for general-purpose power applications, this RoHS-compliant part combines a wide operating temperature range (−55°C to 105°C) and a 2000-hour endurance at 105°C, providing predictable performance for embedded, communications, and industrial electronics that require stable decoupling and ripple handling.

Key Features

• Capacitance & tolerance — 330 µF nominal with ±20% tolerance at 120 Hz, 20°C, giving designers a clear expected capacitance window for decoupling and bulk storage.
• Rated voltage — 6.3 V working voltage suitable for low-voltage power rails and DC–DC converter outputs.
• Low ESR — 25 mΩ measured at 20°C/100 kHz, enabling efficient high-frequency decoupling and reduced power loss.
• High ripple capability — Supports 250 mA at 120 Hz and 2.5 A at 300 kHz, allowing reliable handling of both low- and high-frequency ripple currents.
• Temperature and endurance — Rated for −55°C to 105°C with a load life of 2000 hours at 105°C, offering long-term stability under elevated temperature operation.
• Leakage and tan δ — Leakage current of 700 µA and tan δ of 0.12 (measured at 20°C, 120 Hz), providing measurable electrical characteristics for power-budget and stability considerations.
• Compact SMD package — φ6.3×5.7 mm can with recommended land size of 6.6×6.6 mm; packaged in embossed carrier taping with moisture-proof packing for automated assembly.
• Lead-free reflow compatible — Specified for lead-free reflow soldering conditions with a 260°C peak, suitable for standard SMD assembly processes.
• RoHS compliant — Manufactured to meet RoHS requirements for restricted substances.

Typical Applications

• DC–DC converter output decoupling — Low ESR and high ripple current capability make it suitable for smoothing outputs on compact converters and regulator modules.
• Power rail stabilization in portable devices — High capacitance in a small φ6.3×5.7 mm footprint supports energy buffering and transient suppression in handheld electronics.
• High-frequency power filtering — The 25 mΩ ESR at 100 kHz and rated 2.5 A ripple at 300 kHz support filtering duties in telecom and RF power subsystems.
• Industrial and embedded electronics — Wide operating temperature range (−55°C to 105°C) and 2000 h endurance at 105°C provide reliability for control and instrumentation modules.

Unique Advantages

• High capacitance in a compact SMD can — 330 µF in a φ6.3×5.7 mm package reduces board area compared with larger can-style solutions while maintaining bulk energy storage.
• Low ESR for efficient power delivery — 25 mΩ at 100 kHz minimizes voltage drop and heat generation on high-current rails, improving overall power conversion efficiency.
• Strong high-frequency ripple handling — Rated for up to 2.5 A at 300 kHz, enabling robust performance in switching power applications and high-speed converters.
• Durability at elevated temperatures — 2000-hour life at 105°C provides predictable aging characteristics for designs exposed to sustained thermal stress.
• Assembly-ready packaging — Embossed carrier taping with moisture-proof packing supports automated pick-and-place and standard lead-free reflow processes.
• Measurable electrical parameters — Specified tan δ, leakage current, and ESR values simplify design verification and system-level simulations.
