RNU1V470MCN1

The RNU1V470MCN1 is a conductive polymer aluminum solid electrolytic capacitor in a radial lead can designed for general-purpose electronic applications. It delivers 47 µF at a 35 V rating with low equivalent series resistance and high ripple-current capability, making it suitable for power filtering and decoupling tasks in compact assemblies.

Packaged in a φ8 × 11.5 mm radial can with 3.5 mm lead spacing, the part offers a broad operating range from −55°C to 105°C and a rated life of 2000 hours at 105°C, providing predictable performance in thermally demanding environments.

Key Features

• Capacitance & Voltage — 47 µF nominal capacitance with a rated voltage of 35 V and ±20% tolerance for general-purpose energy storage and smoothing.
• Low ESR & High-Frequency Performance — ESR of 24 mΩ measured at 20°C/100 kHz, minimizing losses in high-frequency circuits.
• High Ripple Current Capability — Rated ripple current of 360 mA at 120 Hz and 3.6 A at 300 kHz, supporting both low- and high-frequency ripple handling.
• Reliability & Endurance — Load life specified at 2000 hours at 105°C, with stable capacitance and ESR performance over the test period.
• Wide Temperature Range — Operates from −55°C to 105°C to suit a variety of environmental conditions.
• Radial Lead Package — φ8 × 11.5 mm can size, lead spacing 3.5 mm ±0.5 mm, supplied in bulk/bag packing (no terminal forming), simplifying through-hole assembly.
• Leakage Current — Specified leakage current of 329 µA (measured after standard conditioning), suitable for typical power applications that tolerate small DC leakage.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU) 2015/863) for regulatory compliance in many markets.

Typical Applications

• Power Supply Filtering — Bulk and high-frequency ripple smoothing in DC power rails where low ESR (24 mΩ) and high ripple capability improve voltage stability.
• DC-DC Converter Output Capacitor — Decoupling and output smoothing in switch-mode regulators, leveraging the 3.6 A ripple rating at high frequencies.
• General-Purpose Embedded Electronics — Energy storage and transient suppression in compact through-hole designs using the radial lead package and compact φ8 × 11.5 mm footprint.

Unique Advantages

• Efficient High-Frequency Performance: The 24 mΩ ESR at 100 kHz reduces power loss and heating in high-speed switching applications.
• Wide Ripple-Handling Range: Dual-spec ripple ratings (360 mA at 120 Hz and 3.6 A at 300 kHz) provide predictable behavior across low- and high-frequency conditions.
• Thermal Endurance: Rated 2000 hours at 105°C for sustained reliability in elevated-temperature environments.
• Compact Radial Form Factor: φ8 × 11.5 mm can with 3.5 mm lead spacing fits space-constrained through-hole designs while enabling straightforward manual or wave solder assembly.
• Regulatory Compliance: RoHS conformity helps simplify product certification and market acceptance.
• Predictable Leakage: Specified leakage current of 329 µA supports designs where controlled DC bias loss is acceptable.
