RR50J681MDN1

The RR50J681MDN1 is a conductive polymer aluminum solid electrolytic capacitor in a radial‑lead can, designed for general‑purpose electronic applications. It pairs ultra‑low ESR construction with high ripple current capability in a compact φ10×12.5 mm package with 5 mm lead spacing.

Key value comes from measurable performance: 680 µF capacitance at 6.3 V with 5 mΩ ESR (20°C/100 kHz), rated ripple current up to 7.22 A at 300 kHz, a wide −55°C to 105°C operating window and a 2000‑hour load life at 105°C. The part is RoHS compliant and available in mass production with bulk/no terminal forming supply.

Key Features

• Core Technology — Conductive polymer aluminum solid electrolytic construction for stable capacitance and inherently low ESR.
• Capacitance & tolerance — 680 µF nominal with ±20% tolerance at 120 Hz, 20°C.
• Low ESR — 5 mΩ measured at 20°C/100 kHz; helps reduce voltage drop and losses under high-frequency loading.
• High ripple current — Rated for 722 mA at 120 Hz and 7.22 A at 300 kHz, supporting demanding AC ripple conditions.
• Reliability & endurance — Load life specified at 2000 hours at 105°C; leakage current specified as 1071 µA (measured condition noted in datasheet).
• Package & mounting — Radial lead can, φ10×12.5 mm size (L: 1.25 × D: 1.00 cm), 5 mm lead spacing; supplied in bulk/no terminal forming for flexible assembly.
• Operating range & polarity — Polarized device rated for −55°C to 105°C operation, 6.3 V rated voltage (7.2 V surge).
• Environmental compliance — Compliant with RoHS (2011/65/EU, (EU)2015/863).

Typical Applications

• General purpose electronic designs — Suitable where a compact, polarized capacitor with low ESR and high ripple handling is required.
• Power decoupling and filtering — Low ESR (5 mΩ) and high-frequency ripple capability (7.22 A at 300 kHz) help reduce voltage ripple in power rails.
• High-frequency circuits — Constructed and specified for performance at 100 kHz and above, supporting designs that place demands on AC ripple performance.

Unique Advantages

• Measurable low-loss performance — 5 mΩ ESR at 20°C/100 kHz provides a quantifiable reduction in AC loss versus higher‑ESR options.
• High ripple capacity across frequencies — Ripple ratings provided for both low and high frequencies (722 mA at 120 Hz; 7.22 A at 300 kHz) allow designers to size components against validated limits.
• Long high‑temperature endurance — 2000 hours at 105°C offers a defined lifetime metric for thermal stress planning and reliability modeling.
• Compact radial format — φ10×12.5 mm can with 5 mm lead spacing fits dense through‑hole layouts while preserving robust lead connections.
• RoHS compliant and production ready — Meets RoHS directives and is available in mass production with bulk/no terminal forming for assembly flexibility.
