RR70J331MDN1

The RR70J331MDN1 is a conductive polymer aluminum solid electrolytic capacitor in a radial lead can designed for general-purpose electronic applications. It combines low equivalent series resistance (ESR) and high ripple current capability in a compact through-hole, radial-lead package.

Key attributes include 330 µF capacitance at 6.3 V, an ESR of 7 mΩ (100 kHz, 20°C), rated ripple current up to 6.1 A at 300 kHz, a rated operating range of −55°C to 105°C, and a 2000 hour load life at 105°C. The part is RoHS compliant and part of Nichicon's RR7 low-ESR family.

Key Features

• Conductive polymer aluminum solid electrolyte Provides inherently low ESR and stable performance consistent with the RR7 series specifications.
• Capacitance and voltage 330 µF nominal capacitance at a rated voltage of 6.3 V.
• Ultra-low ESR ESR specified at 7 mΩ measured at 100 kHz, 20°C to minimize losses and improve transient response.
• High ripple-current handling Rated ripple current of 6.1 A at 300 kHz and 610 mA at 120 Hz (frequency coefficients apply), supporting demanding AC and switching environments.
• Robust temperature and lifetime Operating temperature range −55°C to 105°C with a load life rating of 2000 hours at 105°C.
• Radial lead, compact package Radial can with 5 mm lead spacing and compact dimensions (L: 1.25 × D: 1.00 cm) for through-hole assemblies.
• Environmental compliance Compliant with RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose electronics — Suited for circuits that require reliable bulk capacitance with low ESR for improved voltage stability.
• Through-hole PCB assemblies — Radial lead form and 5 mm lead spacing simplify placement and soldering in traditional PCB layouts.
• High-frequency power stages — Rated ripple current of 6.1 A at 300 kHz and low ESR make it appropriate for switching and high-frequency environments where ripple handling matters.
• Elevated-temperature applications — Specified for operation up to 105°C with a 2000 hour life rating at that temperature for sustained thermal exposure.

Unique Advantages

• Low ESR for improved efficiency: 7 mΩ ESR at 100 kHz reduces losses and supports tighter voltage regulation in power circuits.
• High ripple-current capability: 6.1 A at 300 kHz (and 610 mA at 120 Hz) enables handling of significant AC stress in switching applications.
• Compact radial package: Small can size (1.25 × 1.00 cm) with 5 mm lead spacing offers a space-efficient through-hole solution.
• High-temperature endurance: Rated for −55°C to 105°C with 2000 hours at 105°C, supporting designs exposed to elevated operating temperatures.
• Regulatory compliance: RoHS compliance helps meet environmental and regulatory requirements.
