RNU0G102MDN1

The RNU0G102MDN1 is a radial lead conductive polymer aluminum solid electrolytic capacitor offering 1000 µF capacitance at a 4 V rating. It combines high capacitance density with low equivalent series resistance (ESR) and strong ripple-current capability for general-purpose electronic designs.

Designed for applications that require robust bulk storage, decoupling, and high-frequency ripple handling, the RNU0G102MDN1 delivers measurable performance in a compact φ8×11.5 mm can with a wide operating temperature range of −55°C to 105°C and a rated endurance of 2000 hours at 105°C.

Key Features

• Core Technology  Conductive polymer aluminum solid electrolyte construction provides high capacitance in a small radial can form factor.
• Capacitance & Tolerance  1000 µF nominal capacitance with tolerance −20% to +20% (measured at 120 Hz, 20°C).
• Low Loss / Low ESR  Tan δ (DF) of 0.08 at 120 Hz and an ESR of 7 mΩ measured at 20°C/100 kHz, enabling efficient high-frequency performance.
• High Ripple Current Capability  Rated ripple currents of 570 mA at 120 Hz (low frequency) and 5.7 A at 300 kHz (high frequency) support switching regulator and high-frequency applications.
• Leakage and Reliability  Leakage current specified at 800 µA with a rated life/endurance of 2000 hours at 105°C under rated voltage conditions.
• Mechanical & Packaging  Radial lead mounting, φ8×11.5 mm case size, 3.5 mm lead spacing (±0.5 mm tolerance), available in bulk or bag packing.
• Environmental Compliance  RoHS compliant and in mass production.

Typical Applications

• Power filtering and decoupling  1000 µF capacitance combined with 7 mΩ ESR provides effective smoothing for power rails and local decoupling in compact power supplies.
• Switch-mode power supplies (SMPS)  High-frequency ripple current rating (5.7 A at 300 kHz) supports output smoothing and bulk storage in DC‑DC converters.
• Transient load support  Low ESR and high capacitance help stabilize voltage during transient events in embedded and general-purpose electronics.

Unique Advantages

• High ripple handling: Rated ripple currents of 570 mA (120 Hz) and 5.7 A (300 kHz) reduce heating and extend service life in switching environments.
• Very low ESR: 7 mΩ at 20°C/100 kHz minimizes power loss and improves efficiency in high-frequency circuits.
• Compact radial package: φ8×11.5 mm can with 3.5 mm lead spacing delivers high capacitance in a small footprint for space-constrained boards.
• Wide temperature range and rated life: −55°C to 105°C operation and 2000 hours endurance at 105°C under rated voltage provide predictable long-term performance.
• Production readiness: RoHS compliant and listed as mass production status for reliable sourcing and supply continuity.
