LNK2H122MSEF

The LNK2H122MSEF is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNK series. It delivers 1.2 mF (1200 µF) capacitance at a 500 V rating in a radial can with screw terminals, designed for general-purpose applications that require high-voltage capacitance with secure mechanical connections.

Key value propositions include a long load life under ripple current at elevated temperature (5000 hours at 85°C), RoHS compliance, and specifications aimed at durable performance under high-voltage, high-ripple conditions.

Key Features

• Capacitance & Tolerance — 1.2 mF (1200 µF) nominal with ±20% tolerance (at 120 Hz, 20°C).
• High Voltage Rating — Rated for 500 V DC for high-voltage applications within the specified series range.
• Screw Terminal Mounting — Radial can package with screw terminals for secure, high-current connections and straightforward installation.
• Load Life at Elevated Temperature — Endurance specified as 5000 hours when D.C. bias plus rated ripple current is applied at 85°C; after test and recovery to 20°C, capacitance change is within ±20% of initial value.
• Ripple Current Capability — Rated ripple current of 6.2 A at 120 Hz and 8.68 A at 10 kHz (specified values for the part).
• Operating Temperature Range — −25°C to +85°C for category temperature operation.
• Leakage Current Specification — After 5 minutes at rated voltage, leakage current is specified as not more than 3√CV (µA) or 5 mA, whichever is smaller (C: µF, V: V).
• Insulation & Voltage Proof — Insulation resistance more than 100 MΩ at DC 500 V between terminal and bracket; no abnormality at AC 2500 V for 1 minute between terminal and bracket.
• Polarized Construction — Polar capacitor design consistent with electrolytic technology and screw-terminal connections.
• Physical Size — Dimensions: L 11.5 × D 5.1 cm; maximum seated height listed as 4.528 inch; radial can with screw terminals.
• RoHS Compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-Purpose High-Voltage Circuits — Designed for general-purpose use where a 500 V-rated electrolytic capacitor with substantial capacitance is required.
• High-Ripple Environments — Suitable for applications requiring sustained ripple current at elevated temperature, as defined by the 5000-hour endurance at 85°C with rated ripple current.
• Panel- or Chassis-Mounted Power Assemblies — Screw terminal construction supports secure mechanical and electrical connections in engineered assemblies.

Unique Advantages

• Long Endurance at Elevated Temperature: Specified 5000-hour load life at 85°C under D.C. bias plus rated ripple current, with post-test capacitance change within ±20%.
• High Rated Voltage: 500 V rating enables use in higher-voltage designs without series stacking of lower-voltage capacitors.
• Robust Ripple Handling: Provided ripple current ratings at both 120 Hz and 10 kHz support designs with significant AC stress across a range of frequencies.
• Secure Screw-Terminal Interface: Radial can with screw terminals offers strong, serviceable connections for industrial and equipment installations.
• Measured Insulation and Voltage Proof: Insulation resistance >100 MΩ at DC 500 V and AC 2500 V, 1-minute voltage proof between terminal and bracket, supporting reliable isolation.
• Regulatory Compliance: RoHS compliance aligns the part with restricted-substance requirements specified in the product data.
