LNK2H152MSEFBB

The LNK2H152MSEFBB is a Nichicon LNK-series aluminum electrolytic capacitor in a screw-terminal radial can. It provides 1500 µF capacitance at a 500 V rating with ±20% tolerance and is specified for general-purpose applications.

Designed for installations that require robust high-voltage bulk capacitance, this screw-terminal unit offers long-term endurance (5000 hours at 85°C under rated ripple conditions) combined with defined leakage, impedance and ripple-current characteristics.

Key Features

• Capacitance & Voltage — 1.5 mF (1500 µF) rated at 500 V with ±20% tolerance (measured at 120 Hz, 20°C).
• Screw Terminal Package — Radial can with screw terminals for secure mechanical and electrical connections; nominal bolt size M5 for φ51 dimensions.
• Size & Form Factor — Body dimension φ51 × 130 mm length (L: 13 cm × D: 5.1 cm); terminal pitch (W) 22.0 mm and terminal length (l) 6 mm for the φ51 case.
• Endurance — Load life rated 5000 hours at 85°C when DC bias plus rated ripple current is applied; after the test, capacitance change remains within ±20% of initial value.
• Temperature Range & Low-Temperature Stability — Operating range −25°C to +85°C; impedance ratio Z(−25°C)/Z(+20°C) specified up to 8 (measurement frequency 120 Hz).
• Ripple Current Capability — 7.3 A at 120 Hz and 10.22 A at 10 kHz, supporting higher-frequency ripple conditions.
• Loss Angle (tan δ) — Dissipation factor (tanδ) specified as 0.2 (measurement conditions: 120 Hz, 20°C per series specifications).
• Leakage, Insulation & Voltage Proof — Leakage current after 5 minutes ≤ 3√(C·V) µA or 5 mA (whichever smaller); insulation resistance >100 MΩ at DC 500 V between terminal and bracket; AC 2500 V for 1 minute produces no abnormality.
• Regulatory Compliance & Identification — RoHS compliant; marked with white lettering on a black sleeve.

Typical Applications

• General-purpose systems — For designs that require 1500 µF bulk capacitance at up to 500 V in a screw-terminal package.
• High-voltage bulk storage — Suitable where sustained DC bias and ripple are present and long endurance at elevated temperature is required.
• Panel-mounted power modules — Screw terminals provide secure mounting and reliable connections in systems using radial can capacitors.

Unique Advantages

• High-voltage capability: 500 V rating delivers substantial energy storage for high-voltage circuits requiring large bulk capacitance.
• Long endurance at elevated temperature: 5000-hour rated life at 85°C under rated ripple conditions supports extended field service life.
• Screw-terminal reliability: Screw terminals with M5 nominal bolt size provide robust mechanical and electrical connections for panel and module assemblies.
• Defined ripple performance: Specified ripple currents (7.3 A at 120 Hz, 10.22 A at 10 kHz) allow designers to size the capacitor against actual ripple loads.
• Controlled leakage and insulation: Leakage current formula and >100 MΩ insulation resistance at DC 500 V give predictable behavior for system-level leakage budgets and safety margins.
• Standards-based measurement references: Key parameters (tanδ at 120 Hz, impedance ratio, voltage proof) are specified per the LNK-series datasheet for easier engineering comparison.
