LNR1H104MSE

The LNR1H104MSE is a screw-terminal, polarized aluminum electrolytic capacitor from Nichicon’s LNR series, rated 50 V with 100,000 µF (100 mF) capacitance and ±20% tolerance. Designed for general-purpose power applications, it delivers bulk capacitance and high ripple handling in a radial can with screw terminals (φ63.5 × 100L).

Key value comes from its large capacitance, screw-terminal mounting for secure connections, and long-term endurance characterized at elevated temperature and applied DC bias plus rated ripple current.

Key Features

• Capacitance & Rated Voltage — 100 mF (100,000 µF) at 50 V with ±20% tolerance (120 Hz, 20 °C).
• Mounting & Package — Screw terminal radial can package (Radial, Can - Screw Terminals); body dimension φ63.5 × 100L. Terminal hardware uses M5 nominal terminal bolts for the φ63.5 size.
• Operating Temperature & Lifetime — Specified operating range –40 °C to +85 °C with an endurance rating of 5000 hours at 85 °C under DC bias plus rated ripple current.
• High Ripple Current Capability — Ripple current ratings of 14.2 A at 120 Hz and 16.33 A at 100 kHz, enabling robust AC ripple handling when used with DC bias.
• Leakage Current Specification — After 5 minutes’ application of rated voltage, leakage current is specified as not more than 3√(C·V) µA or 5 mA, whichever is smaller (at 20 °C), providing a measurable acceptance criterion for designs and testing.
• Endurance & Stability — Following the endurance test (5000 h at 85 °C with DC bias and rated ripple) the capacitor meets: capacitance change within ±15%, tan δ ≤ 175% of initial specified value, and leakage current less than or equal to initial specified value.
• RoHS Compliant — Conforms to RoHS requirements for environmental compliance.

Typical Applications

• General-purpose power systems — Bulk capacitance for DC power rails where large energy storage and smoothing are required.
• Power supply reservoir — Long-life bulk reservoir for rectified DC outputs subject to DC bias plus ripple current.
• Industrial power equipment — Rack- or cabinet-mounted power modules and control systems that require secure screw-terminal connections and high capacitance.

Unique Advantages

• Large capacitance in a compact radial can — 100,000 µF at 50 V provides substantial energy storage while using a φ63.5 × 100L package footprint.
• Screw-terminal reliability — M5 terminal bolts and screw-terminal construction enable robust, low-resistance connections for high-current installations.
• Designed for sustained operation — Endurance rating of 5000 hours at 85 °C with DC bias plus rated ripple current offers predictable long-term behavior under defined stress conditions.
• Measured leakage current criteria — Leakage specified as 3√(C·V) µA or 5 mA (whichever is smaller) after 5 minutes, giving a clear acceptance limit for incoming inspection and validation.
• Dual-frequency ripple performance — Specified ripple currents at both 120 Hz and 100 kHz support designs exposed to low- and high-frequency ripple components.
• Regulated tolerance and stability — ±20% capacitance tolerance and documented endurance/shelf-life behavior simplify design margining and lifecycle planning.
