RNE1C221MDN1

The RNE1C221MDN1 is a conductive polymer aluminum solid electrolytic capacitor designed for general-purpose electronic applications that require high capacitance, low ESR and elevated ripple-current capability. Its compact radial-can package and radial lead configuration are optimized for through-hole mounting and lead-free flow soldering conditions.

Built for power handling and smoothing roles in compact circuits, this 220 µF, 16 V polarized capacitor combines a small footprint (6 × 8 mm) with a wide operating temperature range to support reliable performance in a variety of designs.

Key Features

• Capacitance & Voltage — 220 µF rated capacitance at 16 V provides bulk energy storage for power-supply smoothing and decoupling in compact designs.
• Conductive Polymer Electrolyte — Solid conductive polymer construction delivers low equivalent series resistance (ESR) and stable performance under ripple load.
• Low ESR — 13 mΩ ESR measured at 100 kHz (20°C), supporting efficient ripple-current handling and reduced power loss.
• High Ripple Current Capacity — Rated ripple current of 415 mA at 120 Hz and 4.15 A at 300 kHz, enabling robust performance under AC ripple and switching conditions.
• Compact Radial Package — Radial can package with 3.5 mm lead spacing and dimensions L: 6 × D: 8 mm for space-constrained boards.
• Wide Temperature & Life Rating — Operating range of −55°C to +105°C and a rated load life of 2000 hours at 105°C for reliable long-term operation in demanding environments.
• Manufacturing & Compliance — Radial lead type compatible with lead-free flow soldering conditions and compliant with the RoHS directive (2011/65/EU, (EU)2015/863).
• Polarized with Standard Tolerance — Polar capacitor with capacitance tolerance of −20% to +20% for predictable design margins.

Typical Applications

• Power-supply filtering — Low ESR and high ripple-current ratings make this part suitable for smoothing and filtering in DC power rails and regulator outputs.
• Bulk energy storage — 220 µF capacitance provides local energy buffering for transient loads and switching stages.
• Compact through-hole assemblies — Small radial-can footprint and 3.5 mm lead spacing fit dense board layouts that require through-hole mounting and lead-free flow solder compatibility.

Unique Advantages

• Efficient ripple handling: 13 mΩ ESR at 100 kHz and high-frequency ripple ratings reduce heating and improve efficiency in switching environments.
• High ripple-current capability: Rated 415 mA at 120 Hz and 4.15 A at 300 kHz, supporting both low- and high-frequency ripple conditions.
• Space-optimized package: 6 × 8 mm radial can and 3.5 mm lead spacing provide high capacitance in a compact through-hole form factor.
• Wide temperature tolerance: −55°C to +105°C operating range enables use across a broad set of environmental conditions.
• Manufacturing ready: Designed for lead-free flow soldering conditions and shipped RoHS compliant to meet modern assembly and regulatory requirements.
• Predictable lifetime: Rated for 2000 hours at 105°C, providing a defined endurance baseline for thermal-stress planning.
