LNR2D683MSE

The LNR2D683MSE is an aluminum electrolytic capacitor in Nichicon’s LNR series, offered in a screw‑terminal radial can package. It provides 68,000 µF (68 mF) capacitance at a 200 V rated voltage with a ±20% tolerance and a tan δ of 0.25.

Designed for general‑purpose applications that require large bulk capacitance and secure screw‑terminal connections, this part delivers long endurance at elevated temperature (5,000 hours at 85°C) and measurable ripple current capability for power‑side energy storage and smoothing tasks.

Key Features

• Bulk Capacitance: 68,000 µF (68 mF) nominal capacitance, providing substantial energy storage for bulk filtering and reservoir applications.
• High Voltage Rating: 200 V rated voltage suitable where extended DC voltage capability is required within general‑purpose designs.
• Tolerance and Loss: ±20% capacitance tolerance (at 120 Hz, 20°C) with a specified tan δ of 0.25 (measurement conditions per series datasheet).
• Endurance and Reliability: Rated for 5,000 hours at 85°C under DC bias plus rated ripple current; after endurance testing, capacitance change is within ±15%, tan δ remains ≤175% of initial specified value, and leakage current stays at or below the initial specified value.
• Ripple Current Capability: 22.6 A at 120 Hz and 27.12 A at 100 kHz, enabling handling of significant AC components in power circuits.
• Mounting and Package: Screw‑terminal radial can package with φ100 body diameter and 250 mm length (φ100 × 250 L); terminals designed for M8 nominal bolt and standard 3‑leg bracket mounting for sizes φ100 and larger.
• Operating Temperature Range: −25°C to +85°C for rated voltages in the 160–250 V range (per series specifications).
• Leakage Current Specification: After 5 minutes’ application of rated voltage, leakage current is ≤ 3√(C·V) µA or 5 mA, whichever is smaller, where C is capacitance in µF and V is voltage in volts (per datasheet formula).

Typical Applications

• General purpose power systems: For designs requiring a screw‑terminal aluminum electrolytic capacitor with 68,000 µF at 200 V.
• High‑capacitance bulk energy storage: Where large capacitance and sustained performance at up to 85°C are required in a screw‑terminal radial can package.
• Power filtering and smoothing: When designers need a robust, high‑capacitance solution with defined ripple current performance and long endurance.

Unique Advantages

• Large single‑component energy storage: 68,000 µF nominal capacitance reduces BOM count compared with multiple smaller capacitors.
• High DC voltage capability: 200 V rating enables use in higher‑voltage general‑purpose power designs without series stacking.
• Documented endurance: 5,000‑hour life at 85°C with quantified post‑test limits (±15% capacitance change, tan δ ≤175% of initial, leakage ≤ initial), supporting predictable long‑term behavior.
• Robust screw‑terminal connections: M8 nominal bolt terminals and standard bracket mounting simplify heavy‑current connections and mechanical retention.
• Measured ripple handling: Specified ripple currents at 120 Hz and 100 kHz let designers match the part to expected AC stress conditions.
• Clear low‑temperature impedance data: Series specifications include impedance ratio guidance for −25°C to +20°C, assisting low‑temperature performance planning for 160–250 V parts.

Why Choose LNR2D683MSE?

LNR2D683MSE positions itself as a durable, high‑capacitance solution within Nichicon’s LNR screw‑terminal family.
