RNL1C821MDSASQ

The RNL1C821MDSASQ is a conductive polymer aluminum solid electrolytic capacitor in a radial lead can, rated 820 µF at 16 V. It combines high capacitance with low equivalent series resistance (ESR) and high ripple-current capability for general-purpose power applications.

Targeted at designers needing robust smoothing and decoupling in compact assemblies, this part offers long endurance at elevated temperature and RoHS compliance for regulatory alignment.

Key Features

• Core Capacitance & Voltage — 820 µF nominal capacitance at a rated voltage of 16 V with ±20% tolerance (−20% ~ 20%).
• Conductive Polymer Technology — Solid polymer electrolyte construction delivering stable electrical performance and low loss (tanδ 0.12 at 20°C, 120 Hz).
• Low ESR — ESR specified at 8 mΩ measured at 20°C/100 kHz, supporting efficient high-frequency performance.
• High Ripple Current Capability — Rated ripple current of 750 mA at 120 Hz (low frequency) and 7.5 A at 300 kHz (high frequency), enabling effective smoothing under dynamic loads.
• Thermal and Life Reliability — Operating temperature range −55°C to +105°C with a rated load life of 5000 hours at 105°C.
• Radial Lead Package — Compact φ8×20 mm can with 3.5 mm lead spacing (±0.5 mm) supplied in bulk/bag packing; radial lead format suitable for through-hole assemblies.
• Regulatory — RoHS compliant.

Typical Applications

• General-purpose power supply smoothing — Low ESR and high ripple rating make the capacitor suitable for bulk smoothing and energy storage in 16 V rails.
• DC–DC converter output filtering — High-frequency ripple handling at 300 kHz helps reduce voltage ripple on converter outputs.
• Embedded and industrial electronics — Compact φ8×20 mm radial package provides a high-capacitance option for board-level power decoupling in space-constrained designs.

Unique Advantages

• High capacitance in a compact can — 820 µF in a φ8×20 mm housing provides significant energy storage without large board area penalty.
• Low AC loss for efficient filtering — tanδ of 0.12 at 120 Hz and ESR of 8 mΩ at 100 kHz support lower heat generation and improved filtering performance.
• Robust ripple handling — Rated ripple currents of 750 mA (120 Hz) and 7.5 A (300 kHz) allow reliable operation under both low- and high-frequency stress.
• Long endurance at high temperature — 5000 hours at 105°C gives predictable lifetime performance for thermal-stressed applications.
• Through-hole mounting simplicity — Radial lead form with defined lead spacing (3.5 mm) eases placement and soldering in through-hole assemblies.
• Regulatory alignment — RoHS compliance supports use in designs requiring restricted-substance conformance.
