Overview of RL81C331MCNASQ – Conductive Polymer Aluminum Electrolytic Capacitor, 330 µF, 16 V, Radial Lead, Low-Profile (φ8×8)

The RL81C331MCNASQ is a Nichicon RL8 series conductive polymer aluminum solid electrolytic capacitor in a low-profile, radial-lead can (φ8×8 mm). It delivers 330 µF capacitance at a 16 V rating with low equivalent series resistance and high ripple-current capability, offering reliable power-decoupling and filtering in compact, general-purpose electronic designs.

Designed for continuous operation across a wide temperature range (−55°C to +105°C) and specified for a 5000-hour endurance at 105°C, this part is targeted at applications that require low ESR, stable filtering performance, and durability under elevated temperature stress.

Key Features

  • Electrical Performance — 330 µF rated capacitance with ±20% tolerance (measured at 20°C, 120 Hz). Tangent of loss angle (tanδ) 0.12 at 20°C/120 Hz and ESR of 12 mΩ measured at 20°C/100 kHz for low-loss filtering.
  • High Ripple Current Capability — Rated low-frequency ripple current 500 mA (120 Hz) and high-frequency ripple current 5 A at 300 kHz, supporting demanding decoupling tasks across frequency ranges.
  • Leakage and Polarization — Polarized capacitor with a specified leakage current of 1056 µA (after 2 minutes at 20°C under rated voltage), suitable for DC power circuits where controlled leakage is required.
  • Thermal Endurance — Load-life endurance specified at 5000 hours at 105°C, enabling reliable operation in elevated-temperature environments.
  • Compact, Low-Profile Package — φ8×8 mm can with radial leads and 3.5 mm lead spacing (±0.5 mm), supporting space-constrained board layouts and through-hole assembly.
  • Packaging & Compliance — Available in bulk (no terminal forming) and bag packing; RoHS compliant.

Typical Applications

  • Power filtering and decoupling — Low ESR and high ripple-current capability reduce voltage ripple and improve stability in DC power rails and local decoupling networks.
  • Switching regulator output capacitors — Rated ripple current and low ESR support energy smoothing at converter outputs across a range of switching frequencies.
  • General-purpose electronic assemblies — Compact φ8×8 size and radial-lead form factor fit compact boards and through-hole designs requiring robust filtering components.

Unique Advantages

  • Low ESR for effective ripple suppression: 12 mΩ ESR at 100 kHz reduces losses and improves voltage stability in high-frequency applications.
  • Wide ripple-current capability: 500 mA at 120 Hz and 5 A at 300 kHz provide flexibility across both low- and high-frequency power environments.
  • Proven elevated-temperature endurance: 5000 hours at 105°C supports longevity in thermally demanding designs.
  • Compact, low-profile package: φ8×8 mm can and 3.5 mm lead spacing enable dense board layouts where vertical space is limited.
  • Polarized, controlled leakage characteristics: Specified leakage current (1056 µA) allows predictable performance in DC circuits after rated-voltage application.
  • RoHS compliant and packaging options: Environmentally compliant and available in bulk or bag packing for varied assembly processes.

Why Choose RL81C331MCNASQ?

The RL81C331MCNASQ combines conductive-polymer aluminum technology with a low-profile φ8 can and radial-lead configuration to deliver low ESR, high ripple-current handling, and extended high-temperature endurance. It is well suited to designers seeking a compact, reliable electrolytic solution for power filtering and decoupling where stable performance at elevated temperatures is required.

This part is appropriate for general-purpose electronic designs that demand predictable leakage behavior, tight thermal endurance specifications, and flexible mounting/packaging options. Its specification set—330 µF at 16 V, 12 mΩ ESR at 100 kHz, and 5000-hour life at 105°C—supports long-term robustness in dense, thermal-stressed assemblies.
