LGU2F221MELZ

The LGU2F221MELZ is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LGU series, specified at 220 µF and 315 V. It is a radial, can-style, snap-in mounted capacitor designed for general-purpose power applications that require high-voltage bulk capacitance and reliable operation at elevated temperatures.

Key value propositions include a 315 V rating, a wide operating temperature range for this voltage class, and endurance proven under continuous ripple stress at 105 °C—delivering dependable smoothing and energy-storage capability in demanding environments.

Key Features

• Capacitance and Voltage — 220 µF nominal capacitance with a 315 V rated voltage, suitable where high DC voltage bulk capacitance is required.
• High-temperature Endurance — Endurance tested to withstand 3000 hours of DC bias plus rated ripple current at 105 °C; capacitance change remains within ±20% after the test.
• Operating Temperature Range — Specified for −25 °C to +105 °C for the 315–450 V range, enabling use in elevated-temperature equipment.
• Ripple Current Capability — Rated ripple current performance includes 1.04 A at 120 Hz and 1.487 A at 50 kHz, supporting applications with continuous AC ripple on the DC bus.
• Package and Mounting — Radial, can-style snap-in package for secure, through-board snap-in mounting and robust mechanical retention.
• Capacitance Tolerance and Leakage — Capacitance tolerance ±20% (at 120 Hz, 20 °C). Leakage current meets the series specification I ≤ 3·C·V (µA) after 5 minutes’ application of rated voltage at 20 °C.
• Regulatory Compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).
• Compact Footprint — Component dimensions approximately L: 4 cm × D: 2.2 cm with a seated height of 1.575 inch, suitable for space-conscious power assemblies.

Typical Applications

• General-purpose power filtering — Bulk smoothing and decoupling in power supplies where a 315 V rated electrolytic is required.
• High-temperature equipment — Circuits that operate at elevated ambient temperatures up to 105 °C and require long-term ripple endurance.
• Through-board snap-in assemblies — Designs that use snap-in mounting for mechanical stability and straightforward PCB installation.

Unique Advantages

• Proven high-temperature reliability — 3000‑hour endurance at 105 °C under rated ripple current provides specification-backed stability for extended service life.
• High-voltage capability — 315 V rating supports higher DC bus applications without stepping up component count.
• Measured ripple performance — Explicit ripple current values at 120 Hz and 50 kHz enable designers to match capacitor selection to expected operating frequencies.
• Clear leakage specification — Leakage current defined as I ≤ 3·C·V (µA) after 5 minutes at 20 °C, allowing predictable end-of-line and in-system behavior.
• RoHS compliance — Meets current RoHS requirements for restricted substances.
• Compact, secure mounting — Snap-in radial can package simplifies assembly while providing robust mechanical retention.
