RR71C331MDNASQ

The RR71C331MDNASQ is a conductive polymer aluminum solid electrolytic capacitor in a radial lead can, offering 330 µF capacitance at 16 V with a ±20% tolerance. It is designed for general-purpose electronic applications that require ultra-low ESR and high ripple-current capability in a compact radial package.

Key value comes from its low ESR (7 mΩ at 100 kHz), high-frequency ripple handling (6.1 A at 300 kHz), and extended endurance (5,000 hours at 105°C), combined with a wide operating temperature range of −55°C to 105°C and RoHS compliance.

Key Features

• Conductive polymer solid electrolyte  Solid polymer construction for stable electrical performance and reduced ESR compared with traditional wet electrolytes.
• Ultra-low ESR & high ripple current  ESR of 7 mΩ (20°C / 100 kHz) and rated high-frequency ripple current up to 6.1 A (300 kHz) enable efficient handling of high-frequency ripple and fast transient currents. Low-frequency ripple current is specified at 610 mA (120 Hz).
• Long endurance at elevated temperature  Rated life of 5,000 hours at 105°C (endurance test condition), supporting sustained operation in hot environments.
• Electrical characteristics  330 µF capacitance with ±20% tolerance and rated voltage of 16 V; leakage current specified at 792 µA (after 2 minutes at 20°C).
• Radial-lead package & dimensions  φ10 × 12.5 mm can with 5.0 mm lead spacing (lead spacing tolerance ±0.5 mm), supplied in bulk/bag packing for PCB insertion and through-hole assembly.
• Temperature & environmental  Operating range −55°C to 105°C and RoHS compliant.
• Manufacturing compatibility  Radial lead construction is noted as compatible with lead-free flow soldering conditions.

Typical Applications

• General-purpose power filtering  Bulk decoupling and smoothing where low ESR and high ripple capability reduce voltage ripple and improve regulator stability.
• High-frequency power stages  Supports switching supplies and converters that require reliable high-frequency ripple handling up to 300 kHz.
• Embedded and industrial electronics  Compact radial form factor and long life at 105°C suit assembled PCBs used in a range of general-purpose electronic systems.

Unique Advantages

• Low ESR for improved transient response: 7 mΩ ESR at 100 kHz helps reduce losses and voltage drop during fast load changes.
• High ripple capability: Rated ripple current up to 6.1 A at 300 kHz allows use in high-frequency power circuits.
• Extended high-temperature life: 5,000 hours at 105°C supports durability in thermally demanding environments.
• Compact, PCB-friendly radial package: φ10 × 12.5 mm size with 5.0 mm lead spacing for through-hole assembly and manual or automated insertion.
• RoHS compliant: Meets environmental requirements for lead-free production processes.
