RL81C101MDNASQ

The RL81C101MDNASQ is a conductive polymer aluminum solid electrolytic capacitor in a low-profile φ8 radial-can package. Engineered for general-purpose power electronics, it combines ultra low ESR and high ripple current handling with a compact footprint for space-constrained board designs.

Key value comes from measurable performance: 100 µF capacitance at 16 V, 12 mΩ ESR at 100 kHz, high-frequency ripple capability, a wide operating temperature range, and a long load life of 5000 hours at 105°C—attributes that help improve power stability and thermal reliability in demanding circuits.

Key Features

• Core technology — Conductive polymer aluminum solid electrolyte for improved conductivity compared with traditional electrolytes.
• Electrical performance — 100 µF capacitance at 16 V with an equivalent series resistance of 12 mΩ measured at 100 kHz (20°C), delivering low-loss performance for decoupling and smoothing.
• High ripple capability — Rated ripple currents up to 5 A at 300 kHz and 500 mA at 120 Hz enable robust handling of both high- and low-frequency ripple components.
• Low-profile radial package — Compact radial can with φ8 size and 8 mm length (size 8 × 8 mm) and 3.5 mm lead spacing for through-hole mounting in space-limited assemblies.
• Reliability and lifetime — Load life rated at 5000 hours at 105°C, meeting endurance expectations for long-term operation at elevated temperatures.
• Wide temperature range — Specified to operate from −55°C to +105°C to accommodate a broad set of environmental conditions.
• Lead-free solder compatibility and compliance — Radial lead type compatible with lead-free flow soldering conditions and RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose power circuits — Bulk decoupling and smoothing where low ESR and stable capacitance improve regulator and converter performance.
• High-frequency power stages — High ripple current rating at 300 kHz makes it suitable for switching regulators and DC–DC converter outputs.
• Compact or height-constrained designs — Low-profile φ8 can and radial lead form factor for assemblies needing reliable through-hole capacitors without excessive board height.
• Thermally demanding environments — Rated operation to 105°C and a 5000-hour load life at 105°C for applications requiring extended high-temperature stability.

Unique Advantages

• Ultra low ESR — 12 mΩ at 100 kHz reduces I²R losses and improves transient response in power delivery networks.
• High-frequency ripple handling — 5 A ripple rating at 300 kHz supports modern switching topologies and high-speed power stages.
• Space-efficient package — φ8 × 8 mm radial can delivers capacitance density in a compact footprint for constrained board layouts.
• Long high-temperature life — 5000 hours at 105°C provides predictable end-of-life behavior for extended-duty applications.
• Manufacturing-ready — Radial lead design compatible with lead-free flow soldering streamlines assembly for lead-free production lines.
• Regulatory compliance — RoHS compliant to 2011/65/EU and (EU)2015/863 for restricted substances.
