RNL1E122MDS1

The RNL1E122MDS1 is a conductive polymer aluminum solid electrolytic capacitor in a radial-lead can designed for general-purpose electronic applications. It provides high capacitance (1.2 mF) at 25 V with low ESR and elevated ripple-current capability, making it suitable where bulk energy storage and low-loss filtering are required in compact, through-hole formats.

Packaged in a φ10×20 mm can with 5 mm lead spacing and RoHS compliance, this part targets designers who need high capacitance density and reliable performance across a wide temperature range.

Key Features

• High Capacitance — 1.2 mF (1200 µF) nominal capacitance for bulk energy storage and smoothing in general-purpose circuits.
• Rated Voltage — 25 V rated voltage suitable for a range of low-voltage power rails and supply circuits.
• Low ESR — 10 mΩ ESR measured at 20°C/100 kHz, reducing power loss and improving performance in high-frequency environments.
• High Ripple Current — 810 mA at 120 Hz (low frequency) and 8.1 A at 300 kHz (high frequency), supporting demanding ripple conditions.
• Temperature and Endurance — Operating from −55°C to +105°C with a rated life of 2000 hours at 105°C.
• Leakage Current — Specified leakage current of 3000 µA (after 2 minutes at 20°C), enabling predictable bias performance.
• Radial-Lead Package — φ10×20 mm can, radial leads with 5.0 mm spacing (±0.5 mm), available in bulk or bag packing for straightforward through-hole assembly.
• RoHS Compliant — Compliant to the RoHS directive as specified in product data.

Typical Applications

• General-purpose power circuits — Provides bulk capacitance and low ESR for decoupling and smoothing on 25 V rails in general electronic designs.
• Power supply filtering — High ripple-current capability and low loss make it suitable for smoothing ripple in power supplies and auxiliary rails.
• Energy buffering — 1.2 mF capacitance supports short-term energy demands and transient suppression in compact, through-hole layouts.

Unique Advantages

• High capacitance in a compact can — 1200 µF in a φ10×20 mm package reduces board area compared to multiple discrete parts.
• Excellent high-frequency performance — 10 mΩ ESR at 100 kHz and a 8.1 A ripple-current rating at 300 kHz improve efficiency in switching environments.
• Wide operating temperature range — −55°C to +105°C accommodates a broad set of environmental conditions without derating design intent.
• Predictable lifetime — 2000 hours at 105°C provides a defined endurance metric for thermal-stress planning and reliability modeling.
• Through-hole mounting simplicity — Radial-lead form factor with standard 5 mm lead spacing simplifies prototyping and repairable designs.
