RHT0J821MDN1

The RHT0J821MDN1 is a conductive polymer aluminum solid electrolytic capacitor offering 820 µF capacitance at a 6.3 V rating. It combines low equivalent series resistance (ESR) and high ripple current capability in a radial lead, through‑hole package optimized for elevated temperatures.

Designed for general‑purpose electronics, the part delivers reliable filtering and energy storage where high capacitance, low loss, and operation up to 125°C are required. It is RoHS compliant and supports lead‑free flow soldering conditions.

Key Features

• Capacitance & Voltage — 820 µF rated capacitance at 6.3 V with ±20% tolerance for bulk energy storage and decoupling.
• Low ESR — ESR of 12 mΩ measured at 100 kHz (20°C), helping reduce power loss and voltage ripple in high‑frequency circuits.
• High Ripple Current — Rated ripple current up to 1.74 A at 300 kHz (and 174 mA at 120 Hz), enabling robust handling of switching and high‑frequency loads.
• High Temperature Endurance — Operating range −55°C to 125°C with a load life of 1000 hours at 125°C for applications exposed to elevated ambient temperatures.
• Package & Mounting — Radial lead, can package with 5 mm lead spacing for through‑hole mounting and easy assembly or repair.
• Environmental Compliance — Conforms to RoHS directive (2011/65/EU, (EU)2015/863) and corresponds to lead‑free flow soldering conditions.

Typical Applications

• General‑purpose power decoupling — Low ESR and high ripple capability make this part suitable for smoothing and decoupling in power rails.
• High‑temperature electronics — Rated to 125°C with a 1000‑hour life at that temperature, supporting designs exposed to elevated thermal stress.
• Through‑hole assemblies and prototyping — Radial lead package and 5 mm lead spacing simplify insertion into through‑hole PCBs and hand assembly.
• Power supply smoothing — High capacitance and verified ripple current ratings aid energy buffering in low‑voltage power converters.

Unique Advantages

• High capacitance in a compact radial can — 820 µF in a φ10 × 12.5 mm size delivers significant bulk capacitance without large PCB footprint.
• Engineered for low loss at high frequency — 12 mΩ ESR at 100 kHz reduces dissipation and supports efficient high‑frequency operation.
• Validated high‑temperature life — 1000 hours at 125°C provides measurable endurance for thermal‑stressed designs.
• Robust ripple handling — 1.74 A rating at 300 kHz offers headroom for modern switching supplies and high‑frequency converters.
• RoHS and lead‑free solder support — Meets regulatory requirements and is compatible with lead‑free flow soldering processes.
