Overview of RL80J681MCN1 – Conductive Polymer Aluminum Solid Electrolytic Capacitor, 6.3 V, 680 µF, Radial Lead

The RL80J681MCN1 is a conductive polymer aluminum solid electrolytic capacitor in a low-profile φ8×8 mm radial-lead can. Designed for general-purpose power applications, it delivers high ripple-handling and low equivalent series resistance in compact assemblies.

This part targets designers needing high-frequency decoupling and bulk energy filtering in space-constrained boards, offering a combination of low ESR, wide operating temperature range and an endurance rating for elevated-temperature operation.

Key Features

  • Capacitance & Tolerance — 680 µF nominal capacitance with tolerance of -20% to +20% at 120 Hz, 20°C.
  • Rated Voltage — 6.3 V DC rated voltage for low-voltage power rails.
  • Ultra Low ESR — ESR of 8 mΩ measured at 20°C and 100 kHz, enabling efficient high-frequency decoupling and lower losses.
  • High Ripple Current Capability — Low-frequency ripple current of 570 mA (120 Hz) and high-frequency ripple capability of 5.7 A at 300 kHz, supporting fast-switching power circuits.
  • Low Loss (tan δ) — tan δ = 0.12 specified at 20°C, 120 Hz, indicating low dielectric loss for stable performance.
  • Compact, Low-Profile Radial Lead Package — φ8×8 mm can with 3.5 mm lead spacing (±0.5 mm) for dense PCB layouts; available in bulk or bag packing.
  • Wide Temperature Range & Endurance — Rated for operation from -55°C to 105°C with a load life of 2000 hours at 105°C.
  • Leakage Current — Specified leakage current of 856 µA (measured after 2 minutes at 20°C).
  • RoHS Compliant — Complies with RoHS directive (2011/65/EU,(EU)2015/863).
  • Lead-Free Flow Soldering Compatible — Radial lead type corresponds to lead-free flow soldering conditions as noted in the series documentation.

Typical Applications

  • High-frequency power rails — Low ESR (8 mΩ @100 kHz) and high ripple capability (5.7 A at 300 kHz) make this capacitor suitable for decoupling and filtering on switching regulator outputs.
  • Compact DC-DC converter modules — The φ8×8 mm low-profile radial package and 3.5 mm lead spacing support dense board integration where height and footprint are constrained.
  • General-purpose power filtering — 680 µF capacitance and stable performance across -55°C to 105°C enable bulk smoothing and energy storage in a wide range of equipment.

Unique Advantages

  • Efficient high-frequency performance — 8 mΩ ESR at 100 kHz reduces power loss and improves transient response in fast-switching circuits.
  • High ripple handling for real-world loads — Rated ripple current up to 5.7 A at 300 kHz supports demanding switching applications without excessive heating.
  • Space-optimized form factor — φ8×8 mm can and low-profile height aid integration into compact power assemblies and modules.
  • Thermal endurance — 2000 hours at 105°C and a -55°C to 105°C operating range provide predictable performance in elevated-temperature environments.
  • Manufacturing-ready packaging — Offered in bulk (no terminal forming) or bag packing to fit different assembly workflows.
  • Regulatory compliance — RoHS-compliant construction supports regulatory requirements for many markets.
