RL81V101MCN1

The RL81V101MCN1 is a conductive polymer aluminum solid electrolytic capacitor in a low-profile radial lead can (φ8×8 mm) designed for general-purpose electronic applications. It delivers low equivalent series resistance (ESR) and high ripple-current capability in a compact through-hole package.

Key attributes include a 100 µF capacitance at 35 V, low ESR measured at 100 kHz, a wide operating temperature range from −55 °C to +105 °C, and a rated load life of 2000 hours at 105 °C—features that support robust decoupling and bulk energy storage in tightly packaged designs.

Key Features

• Conductive polymer dielectric Solid electrolyte construction provides stable capacitance and low-loss behavior suitable for power decoupling.
• Low ESR ESR of 25 mΩ (measured at 100 kHz) reduces voltage drop under load and improves regulator stability.
• High ripple-current capability Rated ripple currents include 300 mA at 120 Hz and up to 3 A at 300 kHz, supporting both low- and high-frequency power applications.
• Compact, low-profile radial package φ8×8 mm can with 3.5 mm lead spacing provides a small footprint for through-hole assembly while maintaining secure mechanical mounting.
• Wide temperature and endurance Specified for −55 °C to +105 °C operation and a load life of 2000 hours at 105 °C for reliable performance in elevated-temperature environments.
• Polarized, industry-standard tolerance 100 µF with ±20% capacitance tolerance (at 120 Hz, 20 °C) for predictable performance in DC circuits.
• RoHS compliant Meets RoHS directive requirements for lead-free manufacturing environments.

Typical Applications

• Switching power supplies Low ESR and high ripple-current ratings make the capacitor well suited for output decoupling and smoothing in switching regulators.
• Power module decoupling Compact φ8×8 mm package and 100 µF capacitance provide local bulk storage for power modules and DC–DC converters.
• General-purpose industrial electronics Operating range to +105 °C and 2000 h load life support use in control electronics and embedded systems operating at elevated temperatures.

Unique Advantages

• Measurable low ESR (25 mΩ at 100 kHz): Reduces ripple voltage and improves transient response when used for decoupling.
• High-frequency ripple endurance: Rated up to 3 A at 300 kHz, enabling reliable performance in high-switching-frequency applications.
• Space-efficient low-profile design: φ8×8 mm can with 3.5 mm lead spacing allows compact board placement without sacrificing capacitance.
• Wide operating temperature: −55 °C to +105 °C rating supports a range of environmental conditions common in industrial and general-purpose electronics.
• Proven endurance: 2000 hours at 105 °C rated load life provides predictable long-term behavior under elevated thermal stress.
• Polarized, standardized tolerance: ±20% capacitance tolerance and standard radial can format simplify design integration and assembly.
