RNL1C222MDSASQ

The RNL1C222MDSASQ is a conductive polymer aluminum solid electrolytic capacitor in a radial lead can, rated 2200 µF at 16 V. It combines low ESR and high ripple-current capability in a φ10×20 mm package with 5 mm lead spacing for through-hole assemblies.

Designed for general-purpose electronic designs, the part delivers stable operation across an extended temperature range and a long operational life for applications requiring durable bulk capacitance with low loss.

Key Features

• Capacitance and Voltage — 2200 µF nominal capacitance at a 16 V rated voltage with ±20% tolerance (at 120 Hz, 20°C).
• Conductive Polymer Construction — Solid polymer electrolyte for low loss and stable ESR characteristics.
• Low ESR — 8 mΩ equivalent series resistance measured at 100 kHz, 20°C, supporting efficient high-frequency performance.
• High Ripple-Current Capability — Rated ripple current of 8.1 A at 300 kHz and 810 mA at 120 Hz, with frequency coefficients provided by the series specification.
• Wide Temperature Range — Operates from −55°C to +105°C to accommodate elevated ambient and board temperatures.
• Long Load Life — Rated lifetime of 5000 hours at 105°C; the RNL series specifies load-life options of 2000 / 5000 hours at 105°C.
• Package and Mounting — Radial lead can, φ10×20 mm body size with 5 mm lead spacing; supplied in bulk/no terminal forming or bag packing.
• Polarized Device — Polarized aluminum electrolytic capacitor for DC applications.
• RoHS Compliant — Meets RoHS directive requirements.

Typical Applications

• General-purpose electronics — Specified as "General Purpose" to serve a wide range of circuit needs where bulk capacitance, low ESR, and ripple handling are required.
• Through-hole assemblies — Radial lead format and 5 mm lead spacing make the part suitable for conventional through-hole PCB layouts and manual or wave solder processes.
• Elevated-temperature environments — −55°C to +105°C operating range and a 5000-hour rating at 105°C support applications exposed to higher ambient or internal board temperatures.

Unique Advantages

• High capacitance in a compact can — 2200 µF in a φ10×20 mm package provides substantial bulk energy storage with a small board footprint.
• Low-loss, high-frequency performance — 8 mΩ ESR at 100 kHz enables efficient performance in circuits that operate at elevated switching frequencies.
• Robust ripple-handling — High ripple-current ratings at both low and high frequencies reduce heating and extend service life under AC stress.
• Durable under heat stress — Rated 5000 hours at 105°C, offering predictable end-of-life behavior for long-term thermal exposure.
• Standardized through-hole format — Radial lead and common lead spacing simplify PCB layout and assembly for legacy and industrial designs.
• Regulatory compliance — RoHS compliance supports use in regions with restricted substances requirements.
