RS80E122MDN1

The RS80E122MDN1 from Nichicon's RS8 series is a conductive polymer aluminum solid electrolytic capacitor in a radial lead, low‑profile can. It provides 1.2 mF capacitance at a 2.5 V rating with low ESR and high ripple capability for general‑purpose power decoupling and energy storage in compact through‑hole designs.

Designed for applications that require high ripple handling in a small footprint, the device combines a compact φ6.3 × 8 mm package and a wide operating temperature range of −55 °C to 105 °C with a rated endurance of 2000 hours at 105 °C.

Key Features

• Electrical — Capacitance & Voltage 1.2 mF (1200 µF) nominal capacitance with ±20% tolerance at 20 °C, rated for 2.5 V operation.
• Low Loss Characteristics Tangent of loss angle (tanδ) of 0.10 measured at 120 Hz and 20 °C for predictable dissipation characteristics.
• Low ESR Equivalent series resistance of 7 mΩ measured at 20 °C and 100 kHz, supporting reduced power loss and improved transient response.
• High Ripple Current Capability Low‑frequency ripple current of 560 mA at 120 Hz and high‑frequency ripple capability of 5.6 A (5,600 mA) at high frequencies (spec reference at 300 kHz), enabling robust handling of switching currents.
• Leakage Current Specified leakage current of 750 µA after 2 minutes at 20 °C under rated voltage.
• Thermal & Endurance Operating temperature range from −55 °C to 105 °C with a load life (endurance) rating of 2000 hours at 105 °C.
• Mechanical & Mounting Low‑profile radial lead package with dimensions φ6.3 × 8 mm, lead spacing 2.5 mm (±0.5 mm), suited for through‑hole assemblies.
• Packaging & Production Status Available in bulk (no terminal forming) or bag packing; product is in mass production and is RoHS compliant.

Typical Applications

• Power supply decoupling — Provides bulk capacitance and low ESR for smoothing and transient energy demands on DC power rails.
• DC–DC converter output filtering — Handles high ripple currents from switching converters while occupying minimal board area.
• Hold‑up and backup energy — Offers compact energy storage for short‑term hold‑up in compact embedded systems.

Unique Advantages

• High ripple tolerance — Low ESR (7 mΩ) combined with 5.6 A high‑frequency ripple current capability supports demanding switching environments and reduces heating under ripple stress.
• Compact, low‑profile form — φ6.3 × 8 mm radial can provides substantial capacitance (1.2 mF) in a small envelope for space‑constrained through‑hole layouts.
• Wide temperature span — −55 °C to 105 °C operating range enables use across a broad set of ambient conditions without derating the capacitor’s electrical characteristics.
• Engineered endurance — 2000 hours at 105 °C rated life supports sustained performance in elevated temperature environments.
• Through‑hole convenience — Radial lead format with 2.5 mm lead spacing eases assembly in traditional PCB layouts and prototyping.
• RoHS compliant — Manufactured to meet RoHS requirements for materials compliance.
