RNU0J102MCN1

The RNU0J102MCN1 is a radial-lead, conductive-polymer aluminum solid electrolytic capacitor from Nichicon’s RNU series, rated 1000 µF at 6.3 V. It delivers low ESR and high ripple-current capability in a compact φ8 × 11.5 mm can, targeted for general-purpose electronic designs that require robust decoupling and bulk energy storage.

Designed for durability, the device is specified for operation from −55 °C to +105 °C with a rated endurance of 2000 hours at 105 °C, and is RoHS compliant.

Key Features

• Capacitance and Voltage — 1000 µF capacitance at a rated voltage of 6.3 V with tolerance of −20% to +20%.
• Conductive-Polymer Construction — Solid electrolyte for lower ESR compared with traditional wet electrolytics, improving high-frequency performance.
• Low ESR — ESR of 7 mΩ measured at 20 °C / 100 kHz, enabling efficient high-frequency decoupling and reduced power loss.
• High Ripple Current Capability — Rated ripple current of 570 mA at 120 Hz and 5.7 A at 300 kHz, supporting demanding power-supply filtering across frequencies.
• Thermal and Endurance Ratings — Operating temperature range −55 °C to +105 °C and life rating of 2000 hours at 105 °C under rated voltage.
• Physical and Mounting — Radial lead can with dimensions φ8 × 11.5 mm, lead spacing 3.5 mm (±0.5 mm), suitable for through-hole mounting and bulk (bag) packing options.
• Leakage and Loss — Leakage current specified at 1260 µA (measured after 2 minutes at 20 °C) and tan δ ≤ 0.08 at 120 Hz, 20 °C.
• Regulatory — RoHS compliant.

Typical Applications

• General-purpose power filtering — Suited to designs that require bulk capacitance with low ESR and high ripple-current handling.
• Decoupling in power-supply stages — Compact radial package and low ESR help stabilize regulators and intermediate bus rails in a variety of electronic systems.
• High-frequency ripple mitigation — High rated ripple current at 300 kHz makes it useful where elevated AC stress and fast transient filtering are present.

Unique Advantages

• Low-series resistance — 7 mΩ ESR at 100 kHz reduces I²R losses and improves thermal performance under high AC ripple.
• Broad ripple capability — Specified ripple currents of 570 mA (120 Hz) and 5.7 A (300 kHz) provide versatility across low- and high-frequency filtering tasks.
• Compact radial can — φ8 × 11.5 mm package with 3.5 mm lead spacing balances board-space efficiency with through-hole robustness.
• High temperature endurance — 2000 hours rated life at 105 °C supports designs exposed to elevated operating temperatures.
• Predictable dielectric loss — tan δ ≤ 0.08 at 120 Hz (20 °C) for reliable AC performance characterization.
• Regulatory compliance — RoHS compliant for use in lead-restricted supply chains.
