RL80E821MCN1

The RL80E821MCN1 is a conductive polymer aluminum solid electrolytic capacitor in a low-profile radial lead can (φ8×8 mm) with a rated capacitance of 820 µF and rated voltage of 2.5 V. It is designed for general-purpose applications that require low equivalent series resistance (ESR), high ripple-current capability and a compact through-hole footprint.

Key attributes include ultra low ESR, high ripple current handling, a wide operating temperature range from −55 °C to 105 °C, and a rated load life of 2000 hours at 105 °C—making it suitable for power filtering and decoupling roles within general-purpose electronic designs.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with a rated voltage of 2.5 V and capacitance tolerance of −20% to +20% (measured at 120 Hz, 20 °C).
• Ultra Low ESR — ESR of 6 mΩ measured at 20 °C / 100 kHz, enabling low-loss performance at high frequencies.
• High Ripple Current — Rated ripple current 610 mA at 120 Hz and 6.1 A at 300 kHz (frequency coefficient data available), supporting demanding AC current conditions.
• Loss Tangent (tan δ) — tan δ of 0.12 at 20 °C / 120 Hz for predictable dissipation characteristics.
• Leakage Current — 512 µA specified leakage current (measured at 20 °C after 2 minutes' application of rated voltage).
• Endurance & Temperature — Rated life of 2000 hours at 105 °C; operating temperature range −55 °C to +105 °C.
• Package & Mounting — Low-profile φ8×8 mm radial lead (lead spacing 3.5 mm ±0.5 mm, lead diameter approx. 0.6 mm); offered in Bulk (No Terminal Forming) or Bag Packing.
• Compliance — RoHS compliant.

Typical Applications

• Power Filtering and Decoupling — Low ESR and high ripple-current capability make the RL80E821MCN1 suitable for smoothing and decoupling in power rails for general-purpose electronic equipment.
• High-Frequency Power Stages — ESR specified at 100 kHz and high-rated ripple at 300 kHz support use in power conversion and regulator output stages where high-frequency ripple must be managed.
• Compact Through-Hole Designs — The φ8×8 mm low-profile can and radial-lead format fit space-constrained through-hole assemblies that require electrolytic capacitance with high ripple tolerance.

Unique Advantages

• Ultra low ESR for efficient filtering: 6 mΩ ESR at 20 °C/100 kHz reduces losses and improves attenuation of high-frequency noise.
• High ripple capability across frequencies: Rated ripple current values (610 mA at 120 Hz and 6.1 A at 300 kHz) provide headroom for both low- and high-frequency AC stress.
• Compact, low-profile footprint: φ8×8 mm can height and radial leads allow dense placement in through-hole designs without sacrificing performance.
• Wide temperature range and defined endurance: −55 °C to 105 °C operating range with 2000 hours life at 105 °C supports reliable operation under elevated temperature conditions.
• Measured, verifiable electricals: Specified tan δ, leakage current (512 µA), and ESR measurement conditions (20 °C, 100 kHz) support predictable design trade-offs and verification.
• RoHS compliant and radial-lead packaging: Meets RoHS requirements and is available in bulk or bag packing for flexible procurement and assembly workflows.

Why Choose RL80E821MCN1?

The RL80E821MCN1 brings conductive-polymer solid electrolytic performance into a compact radial-lead can, combining 820 µF capacitance at 2.5 V with ultra low ESR (6 mΩ) and strong ripple-current ratings. Its combination of low-profile dimensions, well-defined electrical measurement conditions, and a 2000‑hour rating at 105 °C make it a practical choice for designers needing reliable, high-ripple-capacity components in general-purpose through-hole assemblies.

This part is suited to teams designing compact power supply outputs, filter networks, and other circuits where low-loss, high-frequency stability and predictable endurance are priorities, and where RoHS compliance and standard radial packaging are required.
