RL81C101MCN1

The RL81C101MCN1 is a conductive polymer aluminum solid electrolytic capacitor designed for general-purpose power applications. It combines ultra-low ESR and high ripple-current capability in a low-profile φ8 radial can, offering a compact solution for smoothing and decoupling in space-constrained designs.

Manufactured by Nichicon, this RoHS-compliant capacitor delivers reliable electrical performance across a wide temperature range and is suitable for applications requiring durable, low-loss bulk capacitance.

Key Features

• Capacitance & Voltage — 100 µF rated at 16 V with ±20% tolerance for general-purpose energy storage and filtering.
• Ultra-low ESR — 12 mΩ measured at 100 kHz (20°C) to minimize voltage ripple and power loss in high-frequency circuits.
• High ripple-current capability — Rated for 5 A at 300 kHz and 500 mA at 120 Hz, supporting demanding switching and filtering tasks.
• Compact, low-profile package — φ8×8 mm radial can with 3.5 mm lead spacing for tight board layouts and through-hole mounting.
• Wide operating temperature — −55°C to +105°C to suit thermally varied environments.
• Endurance — Rated lifetime of 2000 hours at 105°C; datasheet endurance criteria specify capacitance, tan δ, ESR and leakage limits after test.
• Radial lead mounting — Polarized radial lead configuration for through-hole assembly and wave solder compatibility.
• RoHS compliant — Meets RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supply decoupling — Reduces output ripple and stabilizes regulators where low ESR and compact bulk capacitance are required.
• High-frequency switching circuits — Supports switching stages with rated ripple current up to 5 A at 300 kHz, improving transient performance.
• Embedded and industrial electronics — Compact φ8 can and −55°C to +105°C range make it suitable for space-constrained boards operating across wide temperatures.

Unique Advantages

• Low-loss operation: 12 mΩ ESR at 100 kHz reduces dissipation and helps maintain voltage stability under load.
• High ripple handling: 5 A ripple rating at 300 kHz provides headroom for demanding switching applications and can reduce the need for multiple parallel components.
• Space-efficient form factor: φ8×8 mm low-profile radial can and 3.5 mm lead spacing enable compact PCB layouts.
• Robust temperature range: −55°C to +105°C ensures consistent performance in varied thermal conditions.
• Durability under stress: 2000 hours at 105°C rated lifetime offers measurable endurance for elevated-temperature applications.
• Regulatory compliance: RoHS conformity supports environmentally constrained product designs.
