RHT1C471MDN1

The RHT1C471MDN1 is a conductive polymer aluminum solid electrolytic capacitor in a radial lead (can) package. It provides 470 µF capacitance at a 16 V rating with polarization and ±20% tolerance.

Engineered for general-purpose use where low ESR and high ripple current are required, the device is specified for operation from −55 °C to 125 °C and a rated load life of 1000 hours at 125 °C.

Key Features

• Capacitance & Voltage — 470 µF rated capacitance at 16 V with ±20% tolerance, suited for bulk energy storage and decoupling in compact designs.
• Low ESR — Equivalent series resistance of 16 mΩ measured at 100 kHz (20 °C), reducing losses and self-heating in high-frequency operation.
• High Ripple Current — Rated ripple current of 152 mA at 120 Hz and 1.52 A at 300 kHz to support circuits with significant AC ripple components.
• High-Temperature Endurance — Operates across −55 °C to 125 °C with a load life of 1000 hours at 125 °C for reliable performance in elevated-temperature environments.
• Radial Lead Package — Radial lead (can) construction with 5 mm lead spacing and compact dimensions (L: 1.25 cm × D: 1 cm) for through-hole mounting.
• RoHS Compliant — Meets RoHS requirements for restricted substances.

Typical Applications

• Power supply decoupling and bulk smoothing — Provides bulk capacitance and low ESR for smoothing voltage rails in designs exposed to elevated temperatures.
• High-ripple circuits — Suitable for circuits that impose high AC ripple currents, leveraging the specified ripple ratings at 120 Hz and 300 kHz.
• High-temperature electronics — Use in equipment and modules that require stable capacitance and endurance at temperatures up to 125 °C.

Unique Advantages

• Improved thermal endurance: Rated for operation to 125 °C with a 1000-hour load life, enabling longer service in hot environments.
• Efficient high-frequency performance: Low ESR (16 mΩ at 100 kHz) reduces power loss and improves performance at switching frequencies.
• High ripple capability: Specified ripple currents (152 mA at 120 Hz; 1.52 A at 300 kHz) allow handling of substantial AC stress without excessive heating.
• Compact through-hole form factor: Radial lead can with 5 mm lead spacing and small L×D footprint provides a space-efficient solution for PCB-level mounting.
• Regulatory compliance: RoHS compliance supports deployment in regions and programs that require restricted-substance conformance.

Why Choose RHT1C471MDN1?

The RHT1C471MDN1 combines conductive polymer technology, low ESR, and proven high-temperature endurance to deliver reliable bulk capacitance and ripple handling in demanding environments. Its radial lead can package and compact dimensions make it practical for through-hole assemblies where space is constrained but thermal and ripple performance remain critical.

This capacitor is well suited for designers requiring a robust, general-purpose electrolytic capacitor that maintains capacitance and low-loss behavior up to 125 °C while meeting RoHS requirements.
