RF80J331MDN1

The RF80J331MDN1 is a conductive polymer aluminum solid electrolytic capacitor designed for general-purpose electronic applications that demand low ESR/ESL and high ripple current capability. It is a radial-lead, low-profile (φ5×8 mm) component rated at 6.3 V with 330 µF capacitance and polarized construction.

Engineered for compact assemblies, this part combines a wide operating temperature range and a specified load life to deliver stable performance in applications where ripple handling and space efficiency are important.

Key Features

• Conductive polymer dielectric — Provides low ESR and low ESL characteristics for improved AC performance and dynamic response.
• Capacitance and voltage — 330 µF nominal capacitance at a 6.3 V rated voltage, tolerance ±20% (120 Hz, 20°C).
• Low ESR — ESR specified at 11 mΩ measured at 100 kHz and 20°C, supporting high-frequency ripple currents.
• High ripple current capability — Rated ripple current up to 3.7 A at 300 kHz (and 370 mA at 120 Hz), enabling robust handling of AC stress in power circuits.
• Compact, low-profile radial package — φ5×8 mm can with 2.0 mm lead spacing and 0.6 mm lead diameter, suitable for confined PCB layouts.
• Wide temperature range and endurance — Operating temperature −55°C to +105°C with a rated load life of 2000 hours at 105°C.
• Assembly and environmental compliance — Radial lead type compatible with lead-free flow soldering conditions and RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose electronic circuits — Useful where low ESR/ESL and measurable ripple handling improve power integrity and transient response.
• Compact power modules — Small φ5×8 footprint and high ripple capacity make it suitable for space-constrained power stages and regulators.
• High-frequency DC filtering — Low ESR at 100 kHz and specified ripple current at 300 kHz support filtering and decoupling in higher-frequency designs.

Unique Advantages

• Low ESR/ESL performance: 11 mΩ ESR at 100 kHz and low ESL improve AC performance and reduce voltage ripple under dynamic loads.
• High ripple endurance: Ripple ratings up to 3.7 A at 300 kHz provide headroom for demanding ripple environments.
• Small, low-profile package: φ5×8 mm can with 2.0 mm lead spacing enables designers to save board space without sacrificing capacitance.
• Robust thermal and lifetime spec: −55°C to +105°C operating range with 2000-hour life at 105°C supports reliable operation in elevated-temperature conditions.
• Lead-free assembly compatibility: Radial lead construction is specified for lead-free flow soldering, simplifying integration into RoHS-compliant manufacturing.
