RR70J221MDN1

The RR70J221MDN1 is a conductive polymer aluminum solid electrolytic capacitor in a radial lead can, optimized for general-purpose electronic designs that require low ESR and high ripple handling. As part of Nichicon’s RR7 series, it delivers ultra-low ESR performance and elevated ripple-current capability in a compact φ8×11.5 mm package with 3.5 mm lead spacing.

Key value propositions include very low equivalent series resistance (7 mΩ at 20°C/100 kHz), high-frequency ripple capability (up to 5.6 A at 300 kHz), and reliable operation across a wide temperature range (−55°C to 105°C) with a rated lifetime of 2000 hours at 105°C.

Key Features

• Conductive polymer solid electrolyte — Polymer construction provides low-loss, stable performance compared with traditional electrolytes.
• Ultra-low ESR — ESR specified at 7 mΩ (20°C/100 kHz) for improved transient response and reduced heat generation in power rails.
• High ripple-current capability — Rated ripple currents of 560 mA at 120 Hz and 5.6 A at 300 kHz support both low- and high-frequency decoupling needs.
• Voltage and capacitance — 220 µF nominal capacitance with a 6.3 V rated voltage and ±20% tolerance for bulk decoupling and energy storage in low-voltage systems.
• Temperature and endurance — Operates from −55°C to 105°C with a rated lifetime of 2000 hours at 105°C, specified to maintain capacitance and ESR within defined limits.
• Compact radial-lead package — φ8×11.5 mm can with 3.5 mm lead spacing and 0.6 mm lead diameter, offered in bulk/bag packing for through-hole assembly.
• Low leakage — Leakage current specified at 69 µA (after 2 minutes at 20°C) for reliable low-current behaviour in DC circuits.
• RoHS compliant — Manufactured in accordance with RoHS directive requirements.

Typical Applications

• General-purpose electronics — Suited to broad applications that require reliable decoupling and bulk capacitance in low-voltage designs.
• Power supply filtering — Low ESR and high ripple-current ratings make it appropriate for smoothing and local energy storage on DC power rails.
• High-frequency decoupling — ESR and ripple performance at 100–300 kHz support decoupling in switching power and high-speed circuits.
• Embedded and industrial systems — Compact radial-lead form factor (φ8×11.5 mm, P=3.5 mm) fits space-constrained through-hole layouts used in control and instrumentation boards.

Unique Advantages

• Low thermal and conduction losses: 7 mΩ ESR at 100 kHz reduces I²R losses and helps maintain cooler operation under ripple stress.
• High ripple endurance: Rated ripple-current up to 5.6 A at high frequency supports robust performance with switching loads and reduces need for parallel capacitors.
• Wide operating range: −55°C to 105°C operation and 2000-hour life at 105°C provide predictable performance in varied environments.
• Compact through-hole package: Radial lead can (φ8×11.5 mm) offers a small footprint for designers preferring through-hole mounting with reliable mechanical retention.
• Predictable leakage behavior: Specified leakage current of 69 µA (20°C) aids designs where standby or bias current budgets matter.
• Regulatory compliance: RoHS compliance simplifies environmental conformance for assembly and product deployment.
