RNL1C821MDSBSQ

The RNL1C821MDSBSQ is an 820 µF, 16 V conductive polymer aluminum solid electrolytic capacitor in a radial lead can (φ8×16 mm). It is part of Nichicon’s RNL series and is designed for general-purpose electronic applications that require low ESR, high ripple-current handling, and extended operating temperature range.

This capacitor delivers a combination of high capacitance in a compact can, low equivalent series resistance, and long endurance (5,000 hours at 105°C), making it suitable for designs where reliable power handling and stability across temperature are important.

Key Features

• Electrical Performance — 820 µF capacitance at 16 V rated voltage with ±20% tolerance; tangent of loss angle (tan δ) 0.12 measured at 20°C, 120 Hz.
• Low ESR — 8 mΩ ESR measured at 20°C/100 kHz, supporting efficient power delivery and reduced dissipation in high-frequency environments.
• High Ripple Current Capacity — Rated ripple current up to 700 mA at 120 Hz and 7.0 A at higher frequencies (300 kHz), with frequency coefficients defined (0.10 at 120 Hz, 1.00 at ≥100 kHz).
• Leakage Current — Typical leakage current 1,312 µA measured after 2 minutes at 20°C under rated voltage.
• Reliability & Life — Endurance rated for 5,000 hours at 105°C under rated voltage, with defined limits on capacitance change, tan δ and ESR after test.
• Thermal Range — Wide operating temperature range from –55°C to +105°C, suitable for varied environmental conditions.
• Mechanical & Mounting — Radial lead package (φ8×16L) with 3.5 mm lead spacing (±0.5 mm); available in bulk (no terminal forming) or bag packing.
• Compliance — RoHS directive compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose electronics — For designs that need a high-capacitance, low-ESR component in a radial-lead, through-hole form factor.
• High-frequency power circuits — Supports high-frequency ripple currents up to 7.0 A (300 kHz+) with low ESR, helpful where high-frequency stability and low loss are required.
• Industrial equipment — Provides durable performance across –55°C to +105°C and is specified for 5,000 hours at 105°C for long-term reliability in demanding environments.
• OEM assemblies and repair — Radial lead form and compact φ8×16 mm can size facilitate straightforward placement and replacement in bulk or bag-packed supply formats.

Unique Advantages

• Compact high-capacitance package — 820 µF in a φ8×16 mm can delivers substantial capacitance while minimizing board footprint for through-hole designs.
• Low measured ESR (8 mΩ) — Reduces energy loss and heat generation at high switching frequencies, improving overall efficiency.
• High ripple-current capability — Rated up to 7.0 A at high frequency, enabling reliable operation in circuits with significant AC ripple.
• Long endurance at elevated temperature — Specified for 5,000 hours at 105°C, providing predictable aging and performance retention for long-life designs.
• Wide operating temperature range — –55°C to +105°C supports use across a broad set of environmental conditions.
• RoHS-compliant manufacturing — Conforms to applicable RoHS directives for environmentally regulated production requirements.
